244 Shear : Notes on Fournier's 



that the Festuca unioloides Wild, is specifically distinct from 

 Br omits unioloides H.B.K. 



Kunth.* regarded the two as distinct and proposed the name, 

 Bromus Willdenowii for Wildenow's plant. Ceratochloa Schraderi 

 Kunth has priority but is also a doubtful synonym, so that we re- 

 gard the adoption of Bromus Willdenozvii Kunth. as the safest. 



Bromus Willdenowii is evidently not common in Mexico, as 

 there are no specimens in the National Herbarium and Fournier, 

 1. c. says that he has seen no Mexican specimens. He, however, 

 cites two numbers — Aschenb. 146, 674 — on the authority of some 

 one else apparently. We have seen none of the specimens cited 

 by Fournier, but his description appears to have been based upon 

 a form of Bromus Willdenowii, probably the one which we called 

 B. unioloides haenkeanus (Presl.) Shear f but which should stand 

 y according to our present understanding of the matter B. Willde- 

 nowii haenkeanus (Presl ) n. comb. Fournier restricts Cerato- 

 chloa to this one species, but according to our interpretation of it 

 as a subgenus all the following forms should also be referred to it. 



Bromus Hookeri Fourn. Mex. PI. 127. 1886 



This name was proposed by Fournier for the plant referred by- 

 Hooker and Arnott in the Botany of Capt. Beechey's Voyage 

 119. 1 84 1 to B. purgans Rich. What Hooker's plant really was 

 we are unable to say. It was collected in Kamtschatka. The 

 name B. Hookeri we do not regard as tenable, however, in any 

 case, as there was already a Bromus Hookerianus Thurber, Wilkes 

 U. S. Expl. Exp. 17 2 : 493. 1874. 



Bromus Hookeri var. a Schaffneri Fourn. /. c. 



This plant as shown by the drawings and spikelet from Four- 

 nier's type no. 42 Schaffner in Herb. Franq., can not be separated 

 from B. carinatus Hookerianus (Thurb.) Shear, so far as we can 

 determine from a careful comparison of the spikelets from the two 

 types. Fournier's plant has a panicle rather more lax than typ- 

 ical Bromus carinatus Hookerianus, otherwise the plants appear 

 alike and can not be satisfactorily separated.
