| Summary: | TAN, A. L., KAMAL, N. M., TAN, H. P. & ROSLAN, I. 2015. Notes on morphological characteristics of Eurycoma <br />spp. and its status in Peninsular Malaysia. Reinwardtia 14 (2): 259 - 263. — A study had been carried out on the genus <br />Eurycoma Jack that aimed to ascertain the diagnostic characteristics of the two species that occur in Peninsular <br />Malaysia. Samples were collected from 15 localities comprising of forest reserves and plantations throughout Peninsu-<br />lar Malaysia covering the 5 regions i.e. northern, western, eastern, southern and central. The sampling was done to <br />capture the morphological variations from different habitat. In general, morphologically both species were very similar. <br />They could be clearly distinguished using their fertile parts. Eurycoma longifolia Jack had long, drooped inflorescences <br />while in E. apiculata A.W. Benn was usually short, pointed upwards. Small differences were also noted on the leaflet of <br />E. apiculata where the apex of the leaflet was often abruptly pointed while its base was rounded with conspicuous <br />petiolule. On contrary, E. longifolia leaflet apex was usually subacute with its base asymmetrical and decurrent to its <br />petiolule. In addition, anatomical transverse section of E. longifolia leaflet midrib outline and margin were dissimilar <br />with E. apiculata by having convex abaxial surface and blunt tip margin compared to the slightly arc-shape abaxial and <br />tapered margin in E. apiculata. The abundancy of Eurycoma spp. had decreased. <br /> |
