Ficus spp. belongs to the tribe Ficeae in the Moraceae family. Many members of this genus have been collected and grown in Bogor Botanic Gardens. There are 519 living collections of Ficus conserved since 1817, and 13 of them have not been identified until the species level. This research aimed to identify the Ficus sp. originated from Kaur Selatan (Bengkulu) using morphological and molecular approaches. Morphological characterization and herbarium specimen observation have been carried out to identify the Ficus sp. The molecular approach was conducted through DNA barcoding using ITS primer. The molecular identification using ITS sequence showed that Ficus sp. is Ficus crassiramea with 99.87% similarity to the sequence in NCBI. Morphological observation through herbarium specimen showed that there are 9 vegetative characters specific to Ficus crassiramea.

History Of

The neotypification of Opuntia australis F.A.C.Weber, basionym of Pterocactus australis (F.A.C.Weber) Backeb., is made here thanks to the discovery of Weber's personal notes about it, and of two notebooks containing respectively a drawing and a short description of that plant, both made at the time of its first collection in 1882. Outlined as well is the poorly documented scientific expedition that made this first discovery and the cultivation of an early plant by F.E. Schlumberger on Weber’s behalf. A Weber’s note confirms he knew the mentioned illustration. A herbarium specimen from the same gathering has been found, but it cannot be considered original material since there is no evidence that it was seen by Weber. However, this specimen is here designated as Epitype.

A New Species

Maesa brevipedicellata, a new species of Maesa ( Primulaceae-Maesoideae) from Papua New Guinea, is described and illustrated based on herbarium specimen observations. The collections of this species resemble M. rufovillosa and were previously determined as that species. Maesa brevipedicellata is unique with its self- supporting habit, hispid hairs throughout and paniculate inflorescences with very short pedicels. This new species mainly differs from M. rufovillosa by the habit (tree/shrub in M. brevipedicellata vs climber in M. rufovillosa) and the inflorescence structure (panicles in M. brevipedicellata vs simple racemes in M. rufovillosa).

National Significance

Naturalised non-native plants that become invasive pose a significant threat to the conservation of biodiversity in protected areas (areas dedicated and managed for long-term conservation of nature), economic productivity of agricultural businesses, and societal impacts including community, culture infrastructure and health. Quantifying the spread, potential dominance and invasion threat of these species is fundamental to effective eradication and development of threat mitigation policy. But this is often hampered by the lack of comprehensive data. This study used existing ecological survey data from 2548 sites and 64 758 Herbarium specimen records to document the status and abundance of non-native plants in two case study bioregions, Cape York Peninsula (CYP) and the Desert Uplands (DEU) in Queensland covering a total area of 186 697 km2. There were 406 non-native species in the CYP, 186 (45.6%) of which are known environmental weeds and 159 non-natives in DEU, of which 69 (43.5%) are environmental weeds. Inside the protected areas, there were 98 species of environmental weeds in CYP, 27 of which are listed as weeds of State significance (Weeds of National Significance (WONS), Queensland declared and non-declared pest plants categories). In DEU, there were 18 environmental weeds inside protected areas and none of them was listed as a weed of State significance. Non-native species that recorded foliage cover dominance in the ecological site data are generally recognised as environmental weeds in Queensland. The threat of weeds from outside of protected areas was serious, with 41 weeds of State significance found in CYP, five of which are WONS, and 25 weeds of State significance found in DEU, 10 of which are WONS.

Marsdenia Tenacissima

<p><em>Marsdenia tenacissima</em> population were found among wild bushes at S 07<sup> o</sup> 47’ 03.4”; E 110<sup>o</sup> 30’ 48.0” about 415 meter above sea level in Gunung Ijo Baturagung Yogyakarta. Identification was based on literature and herbarium specimen. The research was conduct using exploration methods, morphoanatomical observation, and specimen collection. <em>Marsdenia tenacissima</em> in Jawa was not reported in Flora of Java. <em>Marsdenia tenacissima </em>habitus was liana. The specific character for its identification was pollinia’s structure. This paper presented other important character namely leaf, stem, flower, pollinia, and fruit of <em>Marsdenia tenacissima</em> in Gunung Ijo Baturagung Yogyakarta. Accurate description and examination of any plant species were needed for its conservation and awareness of public to local biodiversity.</p>
