MOXSOOX FLORA AT CASTLE ROCK. 483 



Aryostemma courtalli'usp, Am. 



On stone faces beside ii stream in forest. A iilaiit of dense shade. 



Arffostemina verticillatiun, Wall. 



On stones in streams, culvert walls, iV.c., common, and gregarious where 

 it occurs. A delicate and beautiful [>laut with spreading liluiy leaves, and 

 white, star-like (lowers. This plant is recorded in Cooke's Flora B. P. as 

 occurring " on trees in the Wari Country," yWe Dalzell. It is not, however, 

 an epiphyte. Like Be(/onia cronata, Impatiens acaulis, &c., it prefers rocks 

 and stones, but will accept the base of a tree as a substitute. It is a plant 

 of wide distribution, within the Indo-Malayan area, occurring at suitable 

 elevations and humidity along the Himalayas from Kumaon to Sikkim, in 

 Assam, Burma, and Penang. 



Hedyotiii auricularia, Linn. 



On the ground, prostrate, common. Hardly worth mentioning except to 

 note its general resemblance to Sperniacoce Inapida, with which it is liable 

 to be mistaken. 



Oldenlandia dijfusa, Koxb. 



In a damp place on a path in forest. 



Aiiotis rheedii, Benth. and Hook. 



Very abundant in opener places, 



A. quadrilocularis, Hook. f. 



Apparently rather a rare plant in the Presidency, but common at Castle 

 Rock. 



A. foetida, Benth and Hook. 



Very common. 



Opphiorhiza harrisiana, Heyne. 



Common. An extraordinarily variable plant. The maximum length of 

 leaf given by Cooke is 2|" and by Hooker 4", but some of our plants have 

 leaves 5" long. In one case the flowers are pseudo-racemosely disposed 

 along the cyme branches ; in another they form a perfect corymb. The 

 undersurface of the leaves is either green, grey or pink. In no case are 

 the plants with numerous branches as described by Cooke. They are 

 usually simple. 



Lentibulakiace.«. 



Vtricularia arcuata, Wt. 



In one clearing in the forest on sheet rock. A handsome plant. Corolla 

 with a yellow eye, ringed round with white, and outside that pale blue. 



Utviculana affinis, Wt. 



On rocks and gravel, common. Flowers much smaller, and of a much 

 darker and more lurid blue than arcuata. 



TJtriculavia ■■itiiatula, Sni. 



Very common both on stone faces and on trees, growing well up the 

 tree, and not only at the base. The corolla varies from pale violet to pure 

 white, with a yellow eye. 



GeSXEUACI/E. 



Ejnt/iema carnosum, Benth. 



On the face of one culvert. 



A second Gesneraceous plant with a lilmy unequal-sided leaf was coming 

 on at the ends of a railway tunnel.
