Malvastrum ? T collected in the npper valley of the 



Eimac, at between 9000 and 11,000 feet above the sea, two plants 

 which, tliough differing in some respects, must be referred to the 

 same species. The flowers are in dense glomerules on axillary 

 or terminal peduncles, with no indication of the secund inflores- 

 cence so characteristic of Jif, periivianum. The leaves are three- 

 lobed, and the lobes more deeply and sharply toothed than is usual 

 in that species. As Grrisebach has remarked, M. j^eriivianum is 

 an eminently variable species ; and probably my specimens 

 should be referred to it. However that may be, I am inclined to 

 think that a plant in the Kew Herbarium labelled " Malvastrum^ 

 n. sp., No. 90, Parry and Palmer, ^Plants of Central Mexico,' " 

 is not distinct from my plant. 



It is remarkable that although I collected six species ofSida in 

 the lower valley of the Eimac, none of these were seen to ascend 

 above the level of 6000 feet.

 upper valley of the Eimac and about Chicla, ascending to the 

 level of at least 12,500 feet ! 



The wide extension of this species in South America is very 

 remarkable, especially as it has not shown the same readiness 

 to establish itself in North America. In Chili, in Argentaria, 

 and in North Patagonia it has spread throughout the low 

 country ; and it has been observed that it appears to follow 

 domestic animals rather than man, not being seen at new stations 

 in the interior until cattle have been driven there. Its fre-
