Flora of tlie Malayan F^iiinsiila. 101 



compressed, thicker than a crow-quill, pale, glabrous below, pubescent 

 or tomentose towards the apices. Leaves membranous, oblanceolate 

 to elliptic, shortly and rather bluntly acuminate, the base much 

 narrowed ; both surfaces pale-brown when dry and minutely pitted ; the 

 upper glabrous and with the midrib channelled ; the lower sparsely 

 pubescent, the midrib densely so and prominent; main-nerves 7 to 10 

 pairs, spreading but curving upwards at their apices, thin but prominent 

 below; length 3 to 3'75 in.; breadth 1 to 1*5 in.; petiole "1 to "IS in. 

 Stipules connate, pale, coriaceous, forming a narrow cup pubescent out- 

 side at first, but ultimately glabrous, from less than '1 to '15 in. deep, 

 irregularly toothed, persistent. Gymes axillary and terminal, less than 

 half as long as the leaves, trichotomous, the branches 3- or more-flower- 

 ed, often with 2 elliptic acute involucral bracts at the base. Floioers 

 •25 in. long, their pedicels '1 in. Calyx salver-shaped, '15 in. long; the 

 tube narrow, tomentose externally ; the limb with 5 deep oblong blunt 

 spreading or deflexed lobes ; disk large. Ovary 2-celled, 2-seeded. 

 Corolla and Fruit unknown. 



SiNGAPOEE: Ridley 6474, only one specimen seen. 



48. Hydnophttum, Jack. 



Glabrous epiphytic shrubs, with a dilated tuberous fleshy stem, 

 simple or lobed and perforated by ants. Leaves coriaceous, elliptic, ob- 

 tuse. Flowers small, sessile, axillary, solitary or in fascicles, white, 

 Calyx-tuhe ovoid-cjlindric, the limb truncate. Corolla salver or funnel- 

 shaped ; tube short, hairy inside; limb 4-lobed, valvate. Anthers 4, 

 oblong, subsessile on the corolla-throat. Ovary 2-celled; stigma 2- 

 lobed ; ovules one in each cell, basal, erect. Fruit containing two coria- 

 ceous pyrenes surrounded by pulp. Seeds oblong, plano-convex, testa 

 thin with dark lines, embryo in the centre of the fleshy albumen. — 

 DiSTEiB. 3 or 4 species in Malaya, N. Australia, Fiji. 



Htdnophytum formicarium. Jack in Trans. Linn. Soc. XIV. 124. 

 All parts glabrous. Stem tuber-like, smooth, several inches to a foot in 

 diameter, bearing roots from its base and from its apex a few short 

 branches as thick as a goose-quill and compressed near the nodes, pale 

 and striate when dry. Leaves elliptic or elliptic-oblong, sometimes obo- 

 vate, the apex obtuse, the base cuneate ; both surfaces pale-brown when 

 dry ; the midrib distinct on both ; the 6 or 7 pairs of ascending little- 

 curved main-nerves slender on both surfaces and the reticulations obso- 

 lete ; length 25 to 3'5 in. ; breadth 1 to 2 5, petioles '1 to '2 in. Flowers 

 few, "25 in. long, sessile in axillary fascicles. Calyx widely campa- 

 nulate with rounded base and truncate apex. Corolla-tiibe nearly twice 

 as long as the calyx, wide, with 4 tufts of hair in the throat ; limb about
