20 THE GESNERACEiE OF THE MALAY PENINSULA. 



Perak, Larut Hills (Curtis 2042) (Ridley 2916), Scorte- 

 chini (King's Coll. 6170) ; Bujong Malacca (Ridley). 



Distrib. Java, Sumatra (Forbes 1864). Climbing on trees. 



S. Didissandra. 



Shrublets or herbs with short or tall stems hairy, leaves op- 

 posite in remote pairs or crowded at the tip. Flowers solitary 

 on subterminal peduncles or several on short axillary peduncles. 

 Bracts small usually narrow, sepals free to the base or 

 nearly so, 5 lanceolate or ovate, corolla blue white pink 

 or yellow, narrowly tubular dilated upwards, occasionally 

 broadly tubular infundibuliform, limb bilobed usually unequally, 

 lobes rounded. Stamens 4 perfect, in two pairs, filaments 

 long slender, anthers ovate or elliptic adhering by their 

 faces, loculi parallel, connective sometimes prolonged into a 

 horn. Disc annular, small. Ovary cylindric sessile, style as 

 long or longer., stigma broad ovate. Capsule cylindric linear 

 elongate, rarely short and thick, sessile splitting along the 

 upper edge not twisted. 



Species about 20, Malay peninsula and Sumatra. 



Note. — Clarke, in making this genus, included in it several 

 very different sections. I would exclude of these all the 

 species with a short campanulate corolla and short filaments 

 such as his section Stilpnothrix, and reserving his section cyr- 

 tandroides and § speciosae. Of this latter, apparently confined 

 to the peninsula, no species of the originally described sections 

 belong ; they form however a very characteristic group closely 

 allied to some of the Didymocarpi. 



§ 1. Cyrtandroides. Tall shrubs with distant nodes, flowers 



several together in axillary clusters. 

 Leaves minutely crenulate 1. D. frutescens 



Leaves entire 2. D. Johorica 



§ 2. Speciosce. Stems woody short, leaves crowded at the top, 



flowers solitary rarely 2 on subterminal peduncles, 



bractcate plants with the habit of Didymocarpi of the 



section Heterobcea.
