only a single spécimen in Delessert's herbarium, marked Java, La Haye. 

 At ail events it approaches Ch. polyphylla, seeming, however, to 

 hâve a more simple covering of tlie leaves, in the manner of Ch. 

 fragilis. It is tender and pellucid, imperceptibly incrnstated ; the 

 first uncovered joint of the leaves is not quite bidden by the short 

 stipulée ; the foliola are shorter than the seed, which is somewhat less 

 than in Ch. Ceylouica, having a short coronula and only 11-12 striœ 

 on the side. 



East Indian species unknoton to me : — 



Ch. polyclados Don. (ubinam descripta ?) 

 Ch. spiralis herb. Hamilt. (Wallich Cat. 5188). 

 Ch. hispida herb. Madr. (Wallich Cat. 8189). 

 Freiburg, Grand Duchy of Baden, March, 1849.

 the Horticultural and IMr. Pontet's gardens, occupied ail my time. I 

 staid with Dr. Grant, and passed five days at this most pleasant station, 

 making many acquaintances amongst the résidents, from whom I received 

 the usual Indian hospitality. 



I took, as it were, a new departure, on Saturday, April the 8th, my 

 Dawk being laid on that day from Caragola Ghat, about thirty miles 

 down the river, for the foot of the Himalaya range and Darjeeling. 

 Dr. Grant accompanied me to Colgong, half way down the river, onmy 

 course, where we proposed lunching, before I should proceed. Having 

 dismissed the huge boat which I had hired at Mirzapore, I embarked 

 in a much swifter one, kindly lent me by the magistrate of Bhaugul- 

 pore, in which we had no sooner set forth than a heavy easterly gale
