The Family

A survey of the diversity, distribution, and conservation status of the family Lauraceae in southern Mexico was conducted. The diversity account resulted in a list of 120 species representing 10 genera: Aiouea, Beilschmiedia, Cassytha, Cinnamomum, Licaria, Litsea, Mocinnodaphne, Nectandra, Ocotea and Persea. The states of Chiapas, Oaxaca, and Veracruz have the largest numbers of species, particularly for the cloud forest and the tropical rain forest. Endemic species account for 47.5% of the surveyed taxa, which concentrate in Chiapas, Oaxaca, and Veracruz. Only 58 of the species considered in the study are present in the system of nature reserves in southern Mexico. The general implications of these findings for the persistence of this component of the Mexican flora are discussed.

Endemic Plant Species

SummaryWe revise and update the records of strict and near-endemic species of Mt Kupe, Cameroon respectively from 31 strict endemics in 2004, to 25 today, and with near-endemic species 30, unchanged in number but with turnover. The changes result from new collections, discoveries and taxonomic changes in the last 16 years. While 15 of the provisionally named putative endemic species have now been formally published, a further 18 have not. The majority of the 30 near-endemic species (18) are shared with the adjacent Bakossi Mts, far exceeding the numbers shared with the more distant Mt Etinde-Mt Cameroon, Rumpi Hills and Ebo forest areas (sharing three near-endemic species each with Mt Kupe). We test the hypothesis that a further one of the provisionally named putative Mt Kupe species, Vepris sp. 1 from submontane forest near the summit, is indeed new to science. We compare it morphologically with the two other bicarpellate high altitude Cameroon Highland tree species V. montisbambutensis Onana and V. bali Cheek, concluding that it is a new undescribed species here named as Vepris zapfackii. The new species is illustrated and its conservation status assessed as Critically Endangered using the 2012 IUCN standard, due to habitat clearance from agricultural pressures at its sole location which is unprotected. Vepris zapfackii and V. bali appear unique in African trifoliolate species of the genus in having opposite leaves. Vepris zapfackii differs in having hairy petiolules and midribs and petiolules with the blade decurrent distally, narrowing towards a winged-canaliculate base (vs glabrous and petiolule long, terete), and sparsely golden hairy pistillodes and a glabrous calyx (vs densely black hairy pistillodes, and sepals hairy).

Based on physiognomic criteria and a cluster analysis based on 90 plots (14 in prairie and grassland, 35 in shrubs, 38 in forest and 3 in secondary vegetation) we classified the vegetation of Socorro Island. In addition to coastal halophytes, we found evidence supporting eight primary vegetation types: <em>Conocarpus </em> shrubby vegetation, grassland, prairie, <em>Croton masonii </em> shrubby vegetation, <em>Pteridium-Dodonaea </em> shrub, tropical dry forest, tropical rain forest and lower montane cloud forest. Prairie and grassland associations are clearly associated with altitude. Depending on the dominant tree species, three different units could be identified within the tropical rain forest of the island. Our analysis resolved differences with previous classifications of the vegetation on Socorro Island and indicated that some shrubby vegetation, sometimes considered as a different vegetation type, represented instead early succession stages of the lower montane cloud forest. The classifi cation presented constitutes a tool to aid future studies of the flora and fauna of this insular region.

<p>The lichen flora of tropical areas is still much underworked Java in general and Alas Purwo in East Java for specially is no exception. Alas Purwo National Park is representative of a typical lowland tropical rain forest ecosystem in Java. . It is famous with peculiar and endemic species of plant include sawo kecik (Manilkara kauki) and manggong bamboo (Gigantochloa manggong). , beside among the other plants also ketapang (Terminalia cattapa), nyamplung (Calophyllum inophyllum), kepuh (Sterculia foetida), and keben (Barringtonia asiatica). Moreover, in lowland tropical rain forest ecosystem have reported the lichens species diversity is very high and may include over 200 species in 1 ha. There is no reported have found concerning the lichens richness in Alas Purwo. Recently preliminary study of Lichens diversity have been done at triangulation Zone Alas Purwo National Park , East Java. The lichens of the study area have not been treated comprehensively. We explored the lichenological characteristics of putative”tropical lowland cloud forest” (LCF) in a lowland area (0–20ma.s.l.) near Triangulation using macrolichens (cortocoulous species) as indicator taxa We analyzed lichen diversity on 20 trees in two 0,25 ha plots. In tropical lowland forests, corticolous green algal lichens are abundant and highly diverse. This may be related to adaptation to prevailing microenvironmental conditions including, for example, high precipitation and low light intensities. In the understory of a tropical lowland rain forest in Alas Purwo , we studied the morphology and anatomy of corticolous lichens and microcristal test. We found that from Tetrasigma sp , Serbella otodans, Hemandia feltata Baringtonia aciatika Pandanaceae Manilcara cauci Swetinia mahagoni trees there are 30 species of lichens, dominated by Dyorigma sp Graphis and Glyphis from familia of Graphidaceae and Dirinaria Physcia Pyxine Ramalina from familia of Parmeliaceae. The thallus calour was variety from Green-grey, Green-bllue, green, light green, grey, brown, dark green to orange. They have vegetative as wel as generative reproduction such as isidia, soralia, soredia, chypellae, histerothecia, perithecia,and apothecia. The lichenic acids contain such as gyrophoric acid, barbatic acid, usnic acid, atranorin, acid, divaricatic acid and lecanoric acid, </p><p><strong>Keywords</strong>: Alas Purwo, lichens and lichenic acid.</p>

Nepenthes Gracilis

Nepenthes is a type of liana plant (vines) that can grow and develop in the tropical rain forest area. Nepenthes' appearance is very exotic because at of the leaf sheet pockets, appear with different colors and sizes. The unique characteristic that makes this plants different from others. The ability to catch insects that are used as nutrients to help their growth and development, marked by the formation of pockets at the tips of their leaves. The purpose of this research is to identify the species and sites of Nepenthes growth. Obtaining Nepenthes data found in the buffer forests of Sepan sub-village, Lanjak Deras Village, Batang Lupar District, Kapuas Hulu Regency. This study used a field survey method, with multiple plot technique. 45 observational plots were made with a size of 2 x 2 meters each. Six Nepenthes species were found, namely N. ampullaria, N. bicalcarata, N. gracilis, N. mirabilis, N. rafflesiana, N. reinwardtiana. The most common type found in the study site in the Buffor Forest Sepan sub-village, Lanjak Deras Village, is the type of Nepenthes gracilis with a total of 829 individuals. The fewest species found were Nepenthes bicalcarata with 17 individuals. Five from the six types of Nepenthes spp found at the research location were in the IUCN Red List, namely N. ampullaria, N. gracilis, N. mirabilis, N. rafflesiana and N. reinwardtiana included in conservation status, Least Concern (LC) or low risk (IUCN Red List, 2016)Keywords : Identification, Nepenthes, Lanjak Deras sub-village.AbstrakNepenthes merupakan jenis tanaman liana (sulur) yang dapat tumbuh dan berkembang di kawasan hutan hujan tropis.

The study of the forest in rainy environments of the Dominican Republic reveals the presence of four types of vegetation formations, clearly differentiated from each other in terms of their floristic and biogeographical composition, and also significantly different from the rainforests of Cuba. This leads us to propose two new alliances and four plant associations located in northern mountain areas exposed to moisture-laden winds from the Atlantic: All. Rondeletio ochraceae-Clusion roseae (Ass. Cyatheo furfuracei-Prestoetum motanae; Ass. Ormosio krugii-Prestoetum montanae); and All. Rondeletio ochraceae-Didymopanion tremuli (Ass. Hyeronimo montanae-Magnolietum pallescentis; Hyeronimo dominguensis-Magnolietum hamorii). We pay special attention to the description of cloud forest types, since they have a high rate of endemic species, and therefore there are endemic habitats, which need special protective actions. Therefore, we apply the Shannon diversity index to characteristic, companion, non-endemic, and endemic species. As result, the association Ormosio krugii-Prestoetum montanae has a Shannon_T = 2.4 and a value of Shannon_E = 0, whereas the other 3 associations have a better conservation status with Shannon values in all cases > 0: This is due to a worse conservation status of the Eastern Cordillera, in comparison with the Central Cordillera and Sierra de Bhaoruco. Due to human activity, some areas are very poorly conserved, as evidenced by the diversity index and the presence of endemic tree and plant elements. The worst conserved in terms of the relationship between characteristic plants vegetation (cloud forest) in areas with high rainfall are in the Dominican Republic, along with its floristic diversity and state of conservation. This study has made it possible to significantly increase the botanical knowledge of this important habitat.

Abstract. Batuyong MAR, Calaramo MA, Alejandro GJD. 2021. Inventory of Rubiaceae species in Mt. Pao Range, Ilocos Norte, Northwestern Luzon, Philippines. Biodiversitas 22: 3604-3612. Botanical assessments in the Philippines are mostly conducted on declared Protected Areas (PAs). However, many remaining potentially interesting and largely unexplored floristic sites are not considered PA, one of which is the Mt. Pao Range in the Municipality of Adams, located in Ilocos Norte, Philippines. Among the flowering plant family, Rubiaceae is one with the largest number of endemic species and genera in the Philippines Thus, floristic surveys of Rubiaceae species were conducted, and collections were made from September 2019 to March 2021. A total of 39 species belonging to 13 tribes and 24 genera of the family were recorded. These constitute 7.09% of the total Philippine Rubiaceae. Of these species, 18 are Philippine endemics while two are considered narrow endemic to Mt. Pao. Two endemic genera were also found in the area  Antherostele and Kanapia. According to the Updated National List of Threatened Philippine Plants, their conservation status in the Department of Environment and Natural Resources (DENR) Administrative Order No. 2017-11 found one species assessed as Critically Endangered (Antherostele callophylla). This study contributes to the data on the distribution and occurrence of Philippine Rubiaceae. Moreover, it also highlights the area's importance with the presence of threatened and endemic species as an area of concern for protection and conservation.
