MALVACEAE. 147 



The small flowers are noted as "blue;" but the carpels are "exas- 

 perata dentibus alternis plurimis," leaving no doubt that ours is the 

 Linnsean plant. It was gathered also by Dombey in the same district.

Differs (perhaps too slightly) from Malvastrum scoparium [Malva 

 scoparia, L'Her., Cav.) in the more coarsely and sharply toothed 

 leaves, which are not canescent, and in the shorter tubercles rather 

 than awns on the back of the carpels, which moreover are muticous 

 at the proper apex. M. scoparium (to which apparently belongs Sida 

 depressa, Benth. Bot. Voy. Sulph. p. 69), a common plant around 

 Lima, although not in the present collection, has a short and erect 

 cusp at the strongly incurved apex of the carpels, as is described by 

 Cavanilles. 



3. Malvastrum plumosum. 



Malva plumosa, Presl. Rel. Haenk. 2, p. 124 ; Walp. Repert. 1, p. 295. 



Hab. Obrajillo, Peru. (Peru, Matthews, in herb. Hook. No. 776.) 



The carpels are destitute of any awns or processes on the back ; 

 but they bear at the apex a pair of long and slender, woolly-plumose 

 awns : they are nearly membranaceous in texture, minutely downy, 

 not rugose nor reticulated: in dehiscence they separate into two 

 valves,
