Marsda Adisucipto No 1 Yogyakarta 55281, Indonesia. Tel. +62-274-540971, Fax. +62-274-519739 Author correspondency: [email protected] Abstract 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 07o 04 '04.1"; E 110o 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. Keywords: Telosma puberula, Asclepiadoideae, Mount Gedang Atas, Baturagung Mountains Introduction 1836 (MNHN P03858919). Meanwhile, the herbarium of Telosma accedens Collection (Bl.) Back was collected by In an exploration, observation and assessment of wild CA Backer from the Java island (Jember-Bondowoso) in plants in Mount Gedang Atas Baturagung Mountains in 1920 (MNHN P03858922). Yogyakarta, the author was collecting fruits of vines Studies on Telosma cordata or Tonkin flowers hold from family Apocynaceae, sub family Asclepiadoideae are abundant on the internet because this plant is in a community forest at a location of S.07.48'.44.1"; cultivated as floral fragrance plants although there is no E.110.31.15.8". (Widodo, 411m DPL, 26 September identified source from Indonesia. Based on the writer’s 2012). Furthermore, a specimen collection process and knowledge, there are no further information or study observation was completed in a flowering season in about Telosma accedens and Telosma puberula in 2013. The same specimen was also found in Mount Ijo Indonesia after Backer and Bakhuizen (1965: 273), within a radius of 5 km at a location of S.07.47'.04.4 "; Hooker (1885: 38) and Blume (1836). According to The E.110.30'.47.9 ". (Widodo, 415m DPL, 31 December Plant List (2010), the genus Telosma consists of many 2012). From a thorough identification process using species: Telosma accedens (Blume) Backer, Telosma literature and herbarium reviews, it was identified that africana (Nebr.) Nebr., Telosma angustiloba (Warb. In the specimen collected is Telosma sp. Perkins) Merr., Telosma celebica (Warb.) MA Rahman Telosma is belong to Marsdenieae tribe of the & Wilcock, Telosma cordata (Burm. F.) Merr., Telosma subfamily Asclepiadoideae (Takhtajan, 2009: 522). filipes (Schltr.) MA Rahman & Wilcock, Telosma pallida According to Backer and Bakhuizen (1965: 273), there (Roxb.) Craib, Telosma procumbens (Blanco) Merr., and are two types of Telosma in Java: Telosma accedens and Telosma puberula (Miq.) Kerr. Telosma cordata. Meanwhile, Hooker (1885: 38) states Based on the information obtained from Backer and that in Java, there is Telosma puberula (a new name for Bakhuizen (1965: 273) and Hooker (1885: 38), the Pergularia puberula). Telosma cordata (a new name for Telosma species that are available in the Java Island is Pergularia odoratissima) is predicted to be a native to Telosma accedens, Telosma cordata, and Telosma China. In Java, the plant has been cultivated as floral puberula. There is very little information about Telosma fragrance (Backer and Bakhuizen, 1963: 273). accedens and Telosma puberula both in written literature Meanwhile Telosma accedens can be found in Central and published pictures on the internet. This paper Java, East Java and Madura at an altitude of 10-800 m in attempts to present a description of the characteristics, woody shrubs, cleared forests, and teak forests. The specimen and herbarium photographs of Telosma previous name of Pergularia accendens was Telosma specimens found in Mount Gedang Atas and Mount Ijo, accedens, Blume. Backer corrected the name into Baturagung Mountains. The discovery of the Telosma Telosma accedens (Bl.) Back. (Backer, 1949: 63). The species in the Baturagung Mountains Yogyakarta needs name Pergularia accedens was firstly published in to be disseminated to present the richness of flora in Bijdragen tot de flora van Nederlandsch Indie (Blume, Java. Wild plants are no longer recognized despite the 1826). The herbarium of Pergularia accedens was fact that there were some report in the books of flora and collected by Carl L von Blume from the Java island in 48 Biology, Medicine, & Natural Product Chemistry 3 (2), 2014: 47-52 herbarium in the past hundreds years by European Results and Discussion explorers. A publication of plant species in the nature is highly In the exploration, observation and assessment of wild needed in attempt to complete the flora world data, to plants in Mount Gedang Atas Baturagung Mountains in re-check and rediscover old flora, to correct description Yogyakarta, the author collected fruit from the vines of the characters for further research in the study of plant family Apocynaceae sub-family Asclepiadoideae in a biology. The study of Biology is the basis for community forest located at S.07.48'.44.1” location; conservation of earth plants. E.110.31.15.8" (Widodo, 411m DPL, 26 September The purpose of this study is to present a visual 2012). Further, at the initial period of the rainy season at characteristics description of the morphology of leaves, the same location, it was found the shoots with leaves and stems, flowers, pollinia, and fruit of Telosma puberula flowers as such that facilitated further identification found in Mount Gedang Atas and Mount Ijo, Baturagung S.07.48'.44.1 "; E.110.31.15.8 ". (Widodo, 411m DPL, Mountains for identification verification. 31 December 2012). The fruits were initially identified by the author as the fruit of Cynancum callialatum. Another visit conducted at the beginning of the rainy Materials and Methods season 31 December 2012 a set of data was obtained on the habitus and the structure of the specimen because This research employs one kind of research methode that leaves had been grown at the branches and they were explores and visits as well as collects data information flowering. At the same time, an observation at Mount Ijo (exploration and collection trip, (Singh, 1999)). An early which is approximately 5 km from the starting location exploration was performed in September 2012 along with and the author found the same plants which were also an exploration of wild plants. Picture taking was flowering. An identification using the book Flora of completed for the first step of the identification Java, Vol. 2 (Backer and Bakhuizen, 1965: 273) process. Specimen sampling for herbarium was also mentioned that the plant identified was Telosma. performed with an awareness of the preservation of the Subsequent visitations and repeated observations were population. Along with the identification process, then completed on 19 January 2013 and 29 January 2013 monitoring and visitation processes were also kept on to obtain a complete set of on the plant structure (Figure being conducted based on a prediction on the flowering 1 A, B, C, D, E, and Figure 2). The specimen collection season and fruit formation, i.e. December 2012, January process was carried out in the laboratory for further 2013, March 2013, April 2013, December 2013, and observation. On 24 March 2013 visit, a young fruit was October 2014. Flowers specimen collection was identified (Figure 4). completed using wet preservation technique for further Further identification results using the book Flora of identification. Java, Vol. 2 (Backer and Bakhuizen, 1965: 273) showed The tools used for observation and collection were: that this Telosma held the characteristics of Telosma Sony NEX F3 digital camera, Sony Cyber-Shot DSC- accedens (Bl.) Back. A specimen comparison with the W180 digital camera, Canon DSLR digital camera, 1917 Backer herbarium specimens collection in Java rulers, micrometers, calipers, small meter roller, plastic (MNHN P03858922) or Figure 1 F demonstrated the for sample collection, scissors, cutter, paper for labeling, identified specimen compound flower structure of the GPS (Global Positioning System), dried herbarium specimen to be slightly different with the herbarium. collection equipment, flacon bottle, stereo microscope The flowers units on the compound stalks converge or Nikon SMZ 1500 equipped with a camera, Nikon congregate in a way so that the compound flower Eclipse 50 light microscope equipped with Nikon compositions construct a sphere shape, meanwhile the DSF1camera. Materials for observation and collection compound flower at the herbarium exhibited comprise: Aquadest, Alcohol 70%, FAA (Formalin characteristics that shaped like a bunch with Acetic Alcohol) solution. accompanying braktea (supporting leaves). Another Steps of the study include: (1) photograph the comparison with the Telosma procumbens herbarium specimens under natural conditions on site, (2) specimens collection made by Ramos 1918 from Luzon, photograph the specimens under the dried herbarium The Philippines (MNHN P03858921) it was found that process preparation conditions, (3) photograph the the obtained structure of the compound flower to be details of the flower, (4) making the dried herbarium, (5) similar to the specimen of the identified Telosma but photograph the dried herbarium specimens, (6) collecting there was a slight difference in terms of the units of and observing the structures of the preserved flowers, (7) flower. A single flower stalk and crown neck tube of the observing and photographs the pollinia, (8) early specimen was found to be shorter than that of the Telosma identifying of specimens for the member of procumbens. The centre of the crown round end when it Asclepiadaceae based on the book Flora of Java Vol. 2 was still in the form of bud looked much clearer in (Backer and Bakhuizen, 1965), (9) further identifying of Telosma procumbens.
