suspended ovule with the rhaphe internal. In fact, however, the 

 rhaphe is dorsal, and the ovule (which is truly anatropous) is accord- 

 ingly resupinate, as in Sida. There is a similar oversight in the 

 details of the plate of Dr. Hooker's HoJieria Lyallii (Flora of New 

 Zealand, Plate 11, fig. 4, 6), where the radicle is wrongly represented 

 by the artist as superior and dorsal. — The introrse, although terminal, 

 stigmas of this latter plant (those of Hoheria poptdnea being strictly 

 and conspicuously terminal, and so represented both by Raoul and Sir 

 William Hooker), as well as the total want of wings to the fruit, 

 should doubtless exclude it from Hoheria. Notwithstanding the more 

 numerous carpels, I scarcely doubt that it is a congener of Sida pul- 

 chella (Bonpl.*), Hook., and S. Tasmannica, Hook, f.; both of which 

 are species of Plagianthus (including Asterotricliion) , or at least differ 

 from P. sidoides only in having one or two more carpels.

This is the type of a Malvaceous genus, in which the gynaecium is 

 reduced to the last degree of simplicity, P. divaricatus being mono- 

 carpellary. — The excellent figure in the Botanical Magazine, above- 

 cited, represents the stigmas of the sterile flowers : those of the fertile 

 flowers I find (in cultivated specimens) to be more clavate, or even 

 capitate. The figure of the Tasmannian Plagianthus sidoides, Hook., 

 in the same work, Plate 3396 (the Asterotricliion sidoides of Klotzsch), 

 apparently represents the sterile flowers alone. In this also the 

 stigmas of the fertile flowers are more clavate and truncate, and some- 



* The carpels of Sida pulchella are said by DeCandolle to be biaristate. (I have not 

 access to the work in which the species was originally published.) In fruiting specimens 

 of Grunn's plant they are muticous.
