“…Suku Annonaceae memiliki vegetasi dengan habitus tumbuhan memanjat yang kelimpahannya dominan di Asia (Mohd-Ridzuwan et al, 2014). Beberapa marga dari suku Annonaceae yang tergolong dalam tumbuhan memanjat antara lain Artabotrys, Desmos, Uvaria, Mitrella, Fissistigma, Friesodielsia dan Cyathostemma (Nikmah et al, 2019;Turner, 2012).) Beberapa jenis tumbuhan memanjat tersebut dikonservasi secara ex-situ di Kebun Raya Purwodadi (KRP) dan terdapat beberapa spesimen yang masih belum diketahui identitas jenisnya.…”

This study aims to determine the morphological characteristics and climbing types of selected climbing plants from the Annonaceae tribe, conserved ex-situ in the Purwodadi Botanical Gardens (KRP). The method used is observing the vegetative and generative organs of 12 types of qualitatively selected Annonaceae collections. Observational data were scored and analyzed in clusters to determine morphological characteristics and identify the type of climbing plants. The results showed that 2 clusters were referring to the Uvariae and Xylopiae tribes. The distinguishing morphological characteristics of the two clusters were the presence or absence of hooks and the presence or absence of feathers on the vegetative and generative organs. The types of climbing plants of Annonaceae KRP are hook-climbers and twiners. Conservation efforts that need to be done are to maintain and maintain the host of selected climbing plants from the Annonaceae KRP tribe, carry out regular monitoring and explore the potential of these species for environmental conservation education media. In conclusion, the morphological characteristics and types of climbing plants of Annonaceae can determine recommendations for ex-situ conservation efforts.

“…This character is different from its closely related species, Desmos subbiglandulosus. Desmos dumosus, D. subbiglandulosus, and D. cochinchinensis have similarities mainly in the density of indumentum on the abaxial surface of leaves (Ng 2010;Nikmah et al 2019), but they differ in anatomical characters, such as the undulation of the abaxial and adaxial epidermal cells, type and size of crystals on the abaxial and adaxial epidermal cell.…”

Abstract. Nikmah IA, Rugayah R, Chikmawati T. 2020. Leaf anatomical variation in Desmos Lour. and Dasymaschalon (Hook. f. & Thomson) Dalla Torre & Harms species (Annonaceae). Biodiversitas 21: 3317-3330. The relationships between Desmos and Dasymaschalon are debated for along time. Those two genera have high morphological similarities, especially in their generative character (moniliform monocarps). Therefore, sterile specimens of Desmos are difficult to be distinguished from Dasymaschalon. Leaf anatomy in paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. The data were used to support the interspecific and intergeneric delimitation of Desmos and Dasymaschalon. Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type, and size. The anticlinal wall undulation of Desmos is almost straight to slightly wavy, and never sinuous, meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedric, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and drue type C crystals.
