 as in the other genera of this tribe.* 



There is something in the foliage, and in the strigose pubescence of 

 the young parts in Broussaisia that reminds one of Sauranja and 

 Draytonia (p. 206) : the placentae and the seeds are much alike, and 

 the former abound in both with acicular raphides. The stamens and 

 petals of Draytonia, moreover, are slightly perigynous. Although 

 the Saurajea? are doubtless not to be approximated to the Hydrangiece 

 on such grounds, yet they appear to be quite as much related to them 

 as to the Dilleniacece, or even to Cletlira.

A large shrub, or small tree, with stout branches marked with very 

 large leaf-scars, when young hirsute, as is the inflorescence, with 

 strigose hairs, at length glabrate; the pith large. Leaves opposite, 

 obovate-oblong, 4 to 6 inches long, usually pointed with a slight acumi- 

 nation, closely serrate with fine and incurved callous teeth, tapering 

 at the base into the petiole, nearly coriaceous, thickly feather-veined 

 from the stout midrib, and the veins connected by a multitude of 

 transverse veinlets, glabrous above, the midrib and veins beneath 

 strigosely hirsute, especially when young. Petiole 6 to 18 lines long, 

 hirsute when young, stout, margined, channeled above, remarkably 



* Just as this manuscript was about to pass into the printer's hands, Gaudichaud's 

 plate of Broussaisia pellucida, tab. 8, in the Atlas of the Voyage de la Bonite, fell 

 under my notice ;— showing that this botanist had ascertained the real characters of 

 Broussaisia, on his second visit to the Sandwich Islands. No letterpress of the phane- 

 rogamic botany of this work has been published, so far as I am aware, up to the time of 

 M. Gaudichaud's recent death.
