194 LXXV. RUBIACEJE. (J. D. Hooker.) [Saprosma. 



ellipsoid, ^ by in., smooth, crowned by the conical disk, which is girt at its base by 

 the very short calyx-limb. Kurz distinguishes the Andaman form as var. puberuia, 

 with the petioles, stipules, nerves beneath, pubescent.

 when dry, veins reticulate ; petiole - in. ; stipules not seen. Peduncles slender, 

 ^-1 in., bristles at their base very short ; cyme-branches opposite or whorled, slender, 

 horizontal ; bracts and bracteoles minute. Calyx shortly obconic, glabrous. Corolla 

 \ in., papillose, margins of lobes hardly induplicate. Anthers exserted. Style-arms

Epiphytic glabrous shrubs, with a deformed fleshy tuberous simple or lobed 

 stock, excavated by ants; branches square. Leaves opposite, leathery, obtuse;

 sessile, white. Calyx-tube ovoid, limb obscure. Corolla funnel- or salver- 

 shaped, tube long or short ; lobes 4, short, valvate. Anthers 4, subsessile on 

 the corolla- throat, oblong. Ovary 2- celled ; style-arms narrow or broad ; ovules 

 1, basal, erect in each cell. Drupe small; pyrenes 2, plano-convex. Seeds ob-

SOUTH ANDAMAN ISLAND, Kurz. MALACCA; Pulo Bissar, Griffith (Kew Distrib. 

 2975), Maingay (864). DISTRIB. Sumatra, Java, Borneo. 



Tuberous stock 6-14 in., smooth, rooting from its under surface ; branches few, 

 simple, or sparingly divided, stout. Leaves 3-4 by 1-2 in., pale brown when dry, 

 coriaceous, nerves obscure, narrowed into the very short stout petiole. Flowers few. 

 Corolla-tube ~ in., glabrous without ; lobes oblong, acute. Fruit oblong, crowned by 

 the crateriform calyx-limb, smooth, glossy, orange -crimson. The specimens I have 

 seen are very insufficient as to flowers and fruit, the characters of which are in part 

 borrowed from Kurz.

SINGAPORE, A. Wallace. DISTRIB. Malay Archipelago, N. Australia? 



This is a very little known plant, of -which my only materials are tubers and seeds 

 sent by Mr. Wallace in 1865, with an excellent sketch containing some analyses. The 

 sketch represents a nearly globose tuber, 2^ in. diam., excavated by ants, depressed at 

 the top, irregularly grooved, studded with spinules irregularly disposed in longitudinal 

 lines. Short thick simple curved branches, 4-5 in., proceed from a very short stock 

 on the crown of the tuber; these are covered throughout their length with ovoid
