Nepenthes × sharifah-hapsahii
Nepenthes" × "sharifah-hapsahii () is a natural hybrid between "N. gracilis" and "N. mirabilis". It has been recorded from Borneo, Peninsular Malaysia, Sumatra, and Thailand, although it was originally described as a species ("N. sharifah-hapsahii") endemic to Peninsular Malaysia, where it was said to grow at elevations below 1000 m. 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. The taxon was named  after the Universiti Kebangsaan Malaysia Vice Chancellor, Professor Dato' Dr. Sharifah Hapsah Syed Hasan Shahabudin. "Nepenthes" × "ghazallyana" (, after Ghazally Ismail) is a heterotypic synonym of "N." × "sharifah-hapsahii". Description. The stem of this hybrid 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. Identification. "Nepenthes" × "sharifah-hapsahii" most closely resembles "N. gracilis". The table below shows characters that distinguish these two taxa, according to Adam and Hafiza. Adam and Hafiza also noted that "N." × "sharifah-hapsahii" is somewhat similar to "N. tobaica", from which it differs in  several aspects of leaf and inflorescence morphology. Unlike "N. tobaica", "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.
