The fern family Matoniaceae C. Presl (1847: 32) is a small group composed of only two genera, Matonia R. Brown in Wallich (1829: 16) and Phanerosorus Copeland (1909: 344) with three or four species characterized by rhizomes with polycyclic solenosteles covered with thick uniseriate hairs, anastomosing veins in fertile parts of the lamina, peltate and fugacious indusia, relatively large sporangia and gametangia, and tetrahedral, trilete spores (Kramer 1990, Kato & Setoguchi 1998).  The two genera differ from each other in leaf architecture (pedate in Matonia and pinnate in Phanerosorus), habit, and habitat preferences (Phanerosorus pendent and obligately calcicolous and Matonia erect and preferring exposed, sometimes mineralized ridges of high mountains; Kato & Iwatsuki 1985, Barcelona et al. 1996).

A New Species

Orania zheae Adorador & Fernando, a new, slender-stemmed species is described from Samar Island, Philippines. The new combination Orania sibuyanensis (Becc.) Adorador & Fernando is also made, elevating this taxon from variety to species level. The latter species, endemic to Sibuyan Island, is segregated from Orania palindan (Blanco) Merr. (sensu Keim & Dransfield 2012). Both Orania zheae and Orania sibuyanensis are slender undergrowth palms with proportionately diminutive inflorescences borne on very slender peduncles and yellowish globose fruits. But the two species differ from each other in their habitat preferences, reproductive strategies, and in details of flower morphology. Complete descriptions with relevant notes are provided to these two taxa and a determination key to the five Philippine species of Orania is presented.

Hoya incrassata Warb. and Hoya crassicaulis Elmer x Kloppenb, both Philippine endemics have been always thought to be one species. Leaf architecture study of the two controversial species were examined to determine if they have similar characteristics in terms of leaf architecture, the main morphological character used in fossil studies and in taxonomic works dealing with sterile plant specimens. The unifying characters of the two species are the symmetrical and unlobed blade, acuminate apex, entire margin, pinnate primary vein, straight primary vein course, weak brochidodromous secondary vein, moderate relative secondary vein thickness, sinuous secondary vein course, loop-forming branches, enclosed by 3° or 4° arches, composite intersecondary veins, random reticulate tertiary vein, regular polygonal reticulate quaternary vein, looped ultimate marginal venation, and random areole arrangement. The characters blade length to width ratio, blade class and form, base shape, variation in secondary vein angle of divergence, and areole development delineates the two species apart. The study proved that H. incrassata and H. crassicaulis are two different species. Leaf architecture can be of great use when identifying and classifying seemingly similar plant species and sterile specimens. As both species are endemics to the Philippines, conservation ought to be massive as these species can be lost anytime with forest destruction. Conservation strategies could include forest protection and domestication.     Keywords - Botany, leaf architecture, taxonomy, Hoya crassicaulis, Hoya incrassata, Philippines

Upgma Phenogram

The study investigated the leaf architecture and petiole anatomy of eight Dipterocarpus (Dipterocarpaceae) species growing in Mount Makiling Forest Reserve (MMFR) in the Philippines to delineate the species, especially during their non-flowering phase. Leaf and petiole samples from MMFR were examined following the manual on leaf architecture studies. Freehand technique was used to examine the stomata and petiole characters. A UPGMA phenogram was then generated to determine the relationships among Dipterocarpus species using 26 leaf and petiole characters. The most useful characters to delineate Dipterocarpus species are the presence of trichomes, the arrangement of vascular bundles (medullary and outer vascular bundles), areolation, fimbrial vein, and leaf size. Other characters viz., the laminar ratio, blade class, laminar shape, base shape, margin type, and intersecondary, and layers and shape of parenchyma and collenchyma cells were useful as unifying characters. Therefore, certain characters of the leaf architecture and petiole anatomy may be used as taxonomic markers to delineate and correlate the Dipterocarpus species in the Philippines particularly during the nonflowering phase of the species. However, further investigations using samples from the wild populations of the species and molecular techniques may be done to elucidate the taxonomic use of the characters presented in this study.

Specimen Identification

The distribution of Dinochloa scandens is unclear. World bamboo checklists suggest it is relatively widespread in Malesia. Here we clarify issues with herbarium specimen identification. Besides, a synonym name of D. scandens, namely D. macrocarpa collected from the Philippines, needs to be reviewed. The study aims to provide information on distribution and to review the synonym of D. scandens. The habitat preferences of D. scandens are also presented. We carried out targeted fieldwork at Gunung Halimun-Salak National Park in West Java in 2019 and extensive examination of herbarium specimens from Herbarium Bogoriense and online portals to accurately circumscribe this species. All data were analyzed descriptively. Distribution, altitude, and rainfall maps for D. scandens were produced with ArcGIS Pro. Our examination on the specimens suggests that D. scandens is indeed endemic to West Java and Banten Provinces in Indonesia. This bamboo species can be found in lowland to mountain forests with an altitude of 20-1400 m, in areas with annual rainfall between 3000-4000 mm. We support D. macrocarpa as an accepted name for a bamboo species from the Philippines and remove it from synonymy with D. scandens due to clear differences in the fruit compared to specimens of D. scandens across its range.

In 1940 a small group of mathematicians and classicists began to work on Japanese codes with the encouragement of the Australian Army, and several of them began to learn Japanese. In the same year the Censorship Office in Melbourne launched a Japanese course to meet the needs for censors with a command of Japanese. This was the first Allied response to the demand for Japanese linguists. Some of the graduates were posted to Wireless Units in Queensland or the Northern Territory where they derived intelligence from Japanese wireless communications. After US forces had been forced to abandon the Philippines, General Douglas MacArthur had set up his headquarters in Australia. While the US Navy established the Fleet Radio Unit Melbourne, MacArthur created Central Bureau in Brisbane to deal with encrypted messages. This was staffed by graduates of US language schools, the Censorship Office School in Melbourne and Bedford Japanese School. Soon afterwards the Allied Translator and Interpreter Section was formed, which provided linguists to follow the troops as they fought their way towards Japan: they interrogated prisoners and translated documents found on the battlefield.

A New Species

The Tillandsia erubescens group (Bromeliaceae) encompasses seven currently recognized species with reduced, pendulous inflorescences and endemic to pine-oak forests in the high mountains of Mexico. During the course of a taxonomic revision based on extensive study of herbarium specimens and detailed observations in the field, a new species of this group was discovered, which is described and illustrated here as T. tecolometl. The new entity belongs to a subgroup of species with purple corollas that also includes T. andrieuxii, T. macdougallii, T. oaxacana and T. pseudooaxacana. We present detailed morphological comparisons of the new species to the other species in the group with purple corollas, complemented with information on their habitat preferences, geographical distribution and phenology. An identification key to all the species with purple corollas belonging to the Tillandsia erubescens group is provided.

This paper reviews the biodiversity and habitat preferences of living sharks in the Southeast Asian region accumulated from published literatures including journals, books, proceedings, unpublished technical papers, and technical reports as well as authors’ knowledge and experiences working in this field. A total of 196 species of sharks from nine orders and 30 families have been recorded inhabiting from fresh water to deep ocean in this region. Indonesia recorded the highest diversity with 114 species from 27 families followed by the Philippines with 96 species (27 families), Thailand 76 species (21 families), Vietnam 70 species (23 families), Malaysia 68 species (19 families), Myanmar 64 species (19 families), Brunei Darussalam 45 species (15 families), and Cambodia with 26 species from 10 families. Many species still need to be confirmed and are most probably new species. In term of habitat preferences, 83 species of sharks (42.3%) inhabit continental/insular shelves (SHL) followed by continental/insular slopes (SLO) with 48 species (24.5%), shelf to slope (SHS) with 26 species (13.3%), and shelf to oceanic (SHO) with 16 species (8.2%). Only nine species (4.6%) inhabit oceanic and six species (4%) obligate freshwater and euryhaline freshwater/shelves.

In 1620, almost a hundred years after the Virgin of Guadalupe is said to have appeared to Juan Diego on the Hill of Tepeyac, a small group of Spanish nuns paid a visit to the chapel dedicated to Our Lady of Guadalupe. Like many others before and after them they stopped at the shrine on their way to Mexico City. The Franciscan nuns were traveling from Toledo to Manila and were about to cross Mexico to board the yearly Manila Galleon at the port of Acapulco.

And Training

In this chapter is a study of the communication practices of students and their instructors collaborating on virtual team projects as part of small group and team communication classes at three universities — two in the United States, and one in the Philippines. Presented are three themes from student and instructor discourse that emerged as crucial in the development of the teams as they completed the project: negotiation of context, negotiation of roles, and negotiation of technology. The authors hope that attentiveness to these themes by other faculty facilitating virtual team projects in their courses will better equip students to effectively work in virtual teams and lead to greater student learning of the role communication plays in virtual teams. Attentiveness to these themes may also be of use in corporate applied instructional and training situations.

A study was conducted to describle the habitat preference of the Philippines tarsier in Loboc, Bohol. Description of habitat preference was based on species composition and density of the different layers of the stand, mean height, mean diameter and basal area including physical attributes such as aspect, slope and elevation. Three habitat variants of the Philippine tarsier were observed in Loboc, Bohol. The first variant was a relatively open thicket with many small-diameter trees and shrubs and dense undergrowths. The second variant was a thicket of tall grasses, many small diameter trees and dense undergrowths growing under a mahogany plantation. The third variant was a thicket of many small diamater trees and shrubs with less evident woody vines and dense undergrowths with limited exposure to direct sunlight and strong wind being situated along gullies. Preferred habitat of the Phlippine Tarsier are small diameter trees as roosting sites and dense undergrowth as a source of insects and small vertebrates which are preferred food of the animal. The presence of crevices, which are unique to the limestone environment, serve as "hiding places" to protect the animals from predators.
