times three or even four in number. So in Sida Tasmannica, Hook. f., 

 and S. pulchella, BonpL, Hook., the male flowers have the styles re- 

 duced to two, three or four, while those of the fertile flowers are pen- 

 tacarpellary. As both of them equally have pentadelphous stamens, 

 as well as the general aspect of P. sidoides, they should manifestly be 

 referred to the same genus. The ovule, in all of them, is resupinate- 

 suspended, as in Sida. 



Pfagianthus betidinus, Cunn. (to which Dr. Hooker refers P. urti- 

 cinus, Cunn.), also found at the Bay of Islands, does not occur in our 

 collection, so far as I am aware.

Hab. Gathered in a garden at Lima, Peru; the origin not recorded. 



Of this remarkable species, separate leaves and fallen corollas, with 

 the adherent androecium, only were gathered, from a tree which is 

 said in Dr. Pickering's notes to be " 30 feet high, the trunk swelling 

 in the middle, and armed with a few short spines," or prickles. The 

 flowers are said to be "white." The leaves are glabrous, digitately 

 b-9-foliolate ; the leaflets oblong, 2 J to 34 inches long, entire or ob- 

 scurely repand-serrulate towards the apex, which is abruptly and con-
