Evaluation of morphological and anatomical characters on growth of Decalepis hamiltonii wight & arn. In selected regions of Southern Karnataka

Decalepis hamitonii Wight & Arn plants were collected from 5 accessions [i.e., Bannerughatta, Bidadi, Devarayanadurga, Kyatasandra and Savanadurga] and analyzed for morphlogical and anatomical features. The plant exhibited milky latex which is sticky in nature, slightly thicker as compared to that of latex obtained from the members of Asclepiadacaeae and Moraceae. The external morphology of the shrub revealed an woody climber/ liana which produced roots that were pubescent in nature. One of the interesting feature in Decalepis hamitonii Wight & Arn i.e., stout roots without latex but there were presence of mucilagenous fluid which was sticky. The root exhibited variation in pubescent odour which was not detected in other families and genera., ex: Hemidesmus indicus (L.)R.Br. do not possess pubescent odour. Leaves obovate, leaf apex obtuse, base wedge shaped which was a significant character of Decalepis hamitonii Wight & Arn and flowers were trichotomously branched with solitary cyme., floral tube just minute with of 1 mm length. Unlike the altered varieties resembled with those species of Hemidesmus as well. The cultivation of Decalepis hamitonii Wight & Arn in in-vivo condition incured heavy loss or change in morphological features due to climatic conditions. Study of the characters of Decalepis hamitonii Wight & Arn was instantly carried out and analysis revealed that maintainence and protection of wild varieties along with respective characteristics without change in morphology can be done.
