Umbellifee-^. 



Bowlesia palmata, Buiz Sf Pav. ? Chicla ! Upper valley 

 of the Eimac, about 10,000 feet ! The group of species to which 

 this and the following Poiolesice belong appears to be extremely 

 variable ; and I much doubt the constancy of the cliaracters on 

 which several species are founded, nor do I feel confident that 

 those found by me in Peru are liere correctly referred to the 

 species of the authors quoted. 



This is a comparatively large plant, from 12 to 18 inches in 

 height, with numerous suberect branches ; the hairs are stellate;

 This has a feeble little branched stem, rarely erect, beset with 

 long simple hairs, the leaves thin, with verj^ acute angles to the 

 lobes and incisions, the umbels on long peduncles, the fruit beset 

 with stiff stellate hairs.

 Chicla ! This has suberect branches, with stellate hairs, the

and the lateral lobes entire or slightly toothed, the umbels on 

 peduncles equalling the length of the petioles, the hairs of the 

 fruit glochidiate. 



Bowlesia lobata, Puiz S[ Pav., var. httmifitsa, nol, ? Chicla ! 

 A small depressed plant with numerous short prostrate branches, 

 the leaves divided into five equal lobes, the umbek subsessile, or 

 on short peduncles. It is with much doubt that I refer this and 

 the preceding plant to forms of ^. lobata. The typical plant
