The two species of Haploclathra above alluded to as gathered 

 by Mr. Spruce are : — 



1. H. paniculata (Caraipa paniculata, Mart. Nov. Gen. et Sp. pi. i. 

 p. 104, t. 64). 



A tree of 50 to 60 feet, with flesh-coloured, sweet-scented flowers. 

 Frequent on the gapo of the Rio Negro from below Barcellos upwards. 

 It supplies the Mura piranga, i. e. red wood, a timber much prized for 

 cabinet work. R. Spruce, n. 1915. 



2. H. leiantha (Caraipa leiantha, Benth. in Hook. Lond. Journ. Bot. 

 ii. p. 364). 



A tree of 30 to 50 feet, with a white milky juice. Petals white, with 

 pink edges. Frequent throughout the gapo of the Rio Negro. Rob. 

 Schomburgk, 1st coll. n. 935; R. Spruce, n. 1886. 



Having above alluded to the remarkable connecting links between this 

 Order and the generally widely distinct one of Dilleniacea;, I am induced to 

 take this opportunity of noticing a species of the latter Order contained 

 among Mr. Spruce's plants, which requires a few words of comment. I 

 allude to the genus Curatella, Linn., now consisting of two species, both of 

 which were gathered by that zealous collector. One of them is the very 

 common C. americana, Linn., which includes the C.cambaiba, A. de St.- 

 Hil. ; the other, distributed as C. glabra, Spruce, under the no. 2279, from 

 the gapo of the Rio Negro at the Falls of S. Gabriel, proves to be the
