A Discovery and Characteristics Description of Telosma puberula (Asclepiadoideae) in Mount Gedang Atas and Mount Ijo, Baturagung Mountain Yogyakarta Widodo Widodo
Biology, Medicine, & Natural Product Chemistry Vol 3, No 2 (2014)
Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Population of Telosma puberula in community forest bushes was identified at S.07.48'.44.1"; E.110.31.15.8", 411m, Mount Gedang Atas and S 070 04 '04.1"; E 1100 30 '47.9 ", 415m, Mount Ijo. Telosma puberula was also found in Mount Parangan, Mount Mintorogo, Mount Nglanggeran, and Baturagung Mountains Yogyakarta. The identification was based on herbarium specimens collected by Horsfield in 1802 and 1859 from Java island, Indonesia (K000873052, K000873053). Information about Telosma puberula is very limited. This article describe photographs of morphological characters of the plant’s stems, leaves, flowers, and pollinia.

Cosmostigma racemosum is a plant species belonging to the family Apocynaceae, the subfamily Asclepiadoideae. Cosmostigma racemosum is found in Nglanggeran Mountain Gunungkidul, Yogyakarta. The local name and its original distribution are not known. Information or study of Cosmostigma racemosum in Indonesia is not available. Comprehensive characterization of this species is important for authentication and addition of data base. Characterization was conducted by analyzing the morphology and anatomy of flower. The objectives of this study were to describe and analyze the morphology and anatomy of C. racemosum flowers. The method of research was based on observation method and exploration of plant systematics evidence or taxonomy evidence, including analyses and description of morphology and anatomy of flower structure and its development. The results showed that the characteristics of flower morphology are in accordance with the existing description in literatures. Characteristics of pollinia are specific characters of morphological aspect of flower. Data of anatomy of flower and its parts development are the new ones which confirm the position of C.racemosum as a member of the tribe Marsdenieae. The data of anatomy also show new information of the ontogeny of the important parts of flower: pollinia formation, pollinia corpusculum, anther wall, anther sac, stigma, stamen, staminal tube, stigmatic chamber, and structure of ovary in Asclepiadoideae

Macroalgae are very abundant organisms in Indonesian coastal zone. They comprise 8.6% of the total marine organisms.The aim of the research was to identify macroalgae in Waisai Coast Raja Ampat. The results showed that 38 macroalgae were found in Waisai Coast Raja Ampat but only 29 species of macroalgae can be identified. Macroalgae found in Waisai Coast Raja Ampat are green algae, red algae and brown algae. Green algae found and identified are Caulerpa macra (Weber-van Bosse) Draisma & Prud’homme, Caulerpa racemosa var. macrophysa (Sonder wx Kutzing) W.R.Taylor, Caulerpa sertularoides (S.

Publisher : Sunan Kalijaga State Islamic University & Society for Indonesian Biodiversity

Marsdenia tenacissima population were found among wild bushes at S 07 o 47’ 03.4”; E 110o 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. Marsdenia tenacissima in Jawa was not reported in Flora of Java. Marsdenia tenacissima 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 Marsdenia tenacissima 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.
