seminis conformis : cotyledones foliaceae, undulatae, basi emarginatse : radJ- 

 tnila brevissima, obtusa, centrifuga. Plumula inconspicua. 



This very distinct genus was first proposed by me in the 

 " Edinburgh PhilosophicalJournal*;" but not having then seen 

 perfect fruit, the description there given will be found to con- 

 tain some inaccuracies which are now corrected. We are 'n- 

 debted to our indefatigable friend Mr Caldcleugh for samples of 

 a second species of this genus, collected by him at Coquimbo, 

 in Chile. This new species may be named and characterised as 

 follows : 



1. A. canescens, cano-pubescens ; foliorum segmentis linearibus canali- 

 culatis, coroUse tubo calycem parum excedente. 



Hab. in Chili ad Coquimbo. Caldcleugh. If. (v. s. sp. in Herb. Lamb.) 

 Herba habitu graciliore, pube copiosa brevi canescens. Flores minores. 



2. A. radiata, glabra ; foliorum segmentis planis apice dilatatis, co- 

 rollae tubo calyce duplo longiores.
