| Nepenthes sharifah-hapsahii J.H.Adam & Hafiza (2007) |
Nepenthes sharifah-hapsahii (pronounced /nəˈpɛnθiːz ˈʃɑːrɪfɑː hɑːpˈsɑːiːaɪ/, after the Universiti Kebangsaan Malaysia Vice Chancellor, Prof. Dato' Dr. Sharifah Hapsah Syed Hasan Shahabudin) is a tropical pitcher plant native to Peninsular Malaysia, where it grows at elevations below 1000 m.[1]
The type material of N. sharifah-hapsahii was collected by J. H. Adam on the grounds of the Universiti Kebangsaan Malaysia campus on August 2, 2001. Both the holotype (JHA 8000) and isotype are deposited at the university's herbarium.[1]
[edit] Description
The stem of this species is cylindrical, glabrous, and may climb to a height of 5 m. Leaves are leathery in texture, lanceolate or oblong in morphology, and 9 to 20 cm long. Tendrils may be up to 20 cm long. Pitchers are infundibulate in the lower and upper portions and tubular in the middle. They measure up to 15 cm in height and 3.5 cm in width. The peristome is cylindrical and 1 to 2 mm thick. It bears distinct inner teeth and ribs. The lid is orbiculate and covered with numerous glands on the lower surface. N. sharifah-hapsahii has a racemose inflorescence, the axis of which is 30 to 35 cm long. The female inflorescence is unknown at present.[1]
[edit] Taxonomy
N. sharifah-hapsahii appears to be most closely related to N. gracilis. The table below shows the diagnostic characters that distinguish the two species, according to Adam and Hafiza.[1]
Morphological characters Nepenthes sharifah-hapsahii Nepenthes gracilis Shape of upper stem Cylindrical Triangular or angular Lamina base Attenuate into petiole like region and the base not decurrent but clasping stem for about half its circumference Not attenuate into petiole like region and the base decurrent, wings extend almost over one internode Distribution of nectar glands on lower lid surface Numerous nectar glands distributed all over lower lid surface Nectar glands scarcely distributed on lower lid surface Type of digestive glands on inner wall cavity of pitcher Overarched glands: prominently covered by extended epidermal roof conceal more than half of the glands Exposed glands: epidermal roof covering digestive glands poorly developed exposed almost all part of the glands Peristome ribs Distinct Inconspicuous Pedicels 2-flowered on lower 2/3 and 1-flowered on upper 1/3 part of male raceme All 1-flowered
Adam and Hafiza also note that N. sharifah-hapsahii has a close affinity to N. tobaica, from which it differs in several aspects of leaf and inflorescence morphology. Compared to this species, N. sharifah-hapsahii has overarched glands on the inner pitcher wall, one-flowered pedicels on the upper third of the male raceme, and numerous longitudinal veins on the lamina.[1]
Some authors believe N. sharifah-hapsahii represents a natural hybrid between N. gracilis and N. mirabilis.[2]
