Hab. Maldonado, Tweedie : Montevideo in sands of the coast, M. 

 Gibert (specimens from both of above collectors with obscurely repand 

 leaves much more widened above and oblanceolate than in the speci- 

 mens figured from Mr. J. L. Williams Andrews, who speaks of it as 

 one of the most widely distributed plants in Patagonia, in sandy soil, 

 especially of the coast, and occasionally on the higher plateau, extend- 

 ing as far south as the Straits of Magellan). 



The last, or nearly the last, communication we had from our dear 

 Dr. Asa Gray, concerned this plant. ' No doubt it is Boopw crassifolia. 

 But my specimen is in mature fruit.' That which we had sent to him 

 was in flower. This is the more surprising that Dr. Gray when dealing 

 (I.e.) with Mr. Miers's reference of the plant to Acicarpa should have 

 left it in Boopis rather than in Calycera. For I find our single fruit- 

 ing specimen to have conspicuously dimorphic achenes, so that I should 

 not hesitate to refer it to Calycera, though I prefer to let the figure go 

 under an already published name. Indeed Dr. Gray himself says (I.e.), 

 'Although I refer it to Boopis, notwithstanding some difformity in the 

 calyx-lobes of different flowers, and the approach to a subulate 

 character in the narrower ones, I am inclined to think that even 

 Boopis is 

 Calycera. 7 



Boopis is likely to be reduced to a mere section of the original genus 



with vivid green

foliage, smooth and bright on the upper surface, and large yellow 

 blossoms, growing to a height of 1 to 2 feet.— D. Oliver.
