190 wight's botanical LETTiillS. 



as these are, I have still to regret that they do not form a 

 complete series, and still more so that it is utterly impossible 

 for me to do more now than send you a few selections of such 

 as I believe you have not formerly received. Within four 

 days from this date I hope to be fairly under canvas (in 

 tents,) there to remain during at least four months, perhaps 

 more. In the course of that time I expect to visit much inter- 

 esting country, and get abundance of fine plants; but as I 

 know not what is to become of me afterwards, I cannot say 

 when you are likely to reap the benefit. You will find by 

 the present envoi that I have at length discovered the genus 

 Hiimholdtia in the Peninsula. I am uncertain whether two 

 or only one species : neither is in flower, and one only in 

 fruit; it is a magnificent tree, and if, as 1 think, it be new, 

 I intend to associate your name with it. The other, of which 

 there are only leaves, appears to be different, and more like 

 H. Brunonis, Wall. Do not suppose that the one in fruit 

 {H. Arnottiana^ mihi) is not furnished with the peculiar sti- 

 pules because they are not on the specimens, for in truth it 

 was by them that I first recognised the tree. On the same 

 day, but on the Courtallum side of the hills, I found the 

 Trichopodinm in abundance; you will receive specimens of it, 

 as well as of another which I got in Ceylon. There appeared 

 to be several species of that genus, as well as of Acrotrema: 

 of this last those which I saw in Col. Walker's possession 

 differ from mine, found both at Courtallum and in Malabar. 

 Col. Walker says he sent specimens to Graham. 



24:th Julp. — When looking out specimens of some species 

 of PolycarpcBa to-day, I was led to re-examine all the genus, 

 as far as regards India ; and, in doing so, saw reason to think 

 that our two species are only one, or if they be kept distinct, 

 that other characters must be found for them. I have ac- 

 cordingly united them under the name of P. polyrnorpha, and 

 have added three new species : two of them are I think 

 really good ; the third, P. aurea, I have doubts about, as its 

 character principally depends on the colour of the sepals. 1 

 propose to distinguish them by the relative size of the petals
