Mexican Species and Varieties of Bromus 245 



Bromus Hookeri var. /9 marginatus Fourn. /. c. 



This is given as a synonym of B. marginatus Nees in Steudel 

 Syn. PL Gram. 322. 1854, but differs from that plant as we un- 

 derstand it in its rather lax, somewhat drooping panicle, longer, 

 more acute, and smooth empty glumes, and scabrous flowering 

 glume. We propose for this plant the name Bromus proximus 

 nom. nov. The specimen from which the spikelet examined was 

 taken and the sketch made was no. 1488 Botteri & Sumchrast. 

 The first specimen cited by Fournier, which we should prefer to 



■ 



regard as the type of the species, is no. 961 F. Mueller, collected 

 at Orizaba. Nos. 5, 7, 226, Dr. E. Palmer, Saltillo, 898 and no. 

 171a of the same collector from the city of Durango and vicinity, 

 June, 1 896, we should refer to this species. 



Bromus Hookeri var. y Schlechtendalii Fourn. /. c. 



We have drawings and spikelets from two of the specimens 

 cited by Fournier — no. 402 Berlandier " inter Tampico et Real 

 del Monte" and no. 1420 bis Virler, San Luis de Potosi. The 

 spikelet from Berlandier's specimen does not agree with the de- 

 scription which says the flowering glume is very shortly and 

 sparsely pilose. The plant is closely related to Bromus proximus } 

 and may perhaps be best referred to it as a variety until more in- 

 formation can be secured regarding it. According to the description, 

 sketches, and spikelets it differs from Bromus proximus 'in the slightly 

 longer and more acute empty glume, and somewhat pubescent flower- 

 ing glume with a slightly longer awn and a small contracted panicle. 

 This plant we would designate Bromus proximus Schlechten- 

 dalii n. comb. We would refer no. 734 Dr, Edward Palmer's col- 

 lection, September, 1896, from the city of Durango and vicinity, 

 to this variety.

P 



L. Sp. PI. ed. 2. 1 : 113. 1762. The misinterpretation of Lin- 

 naeus's species is evidently due to his reference 1. c. to Feuillet's 

 plate. Fournier' s variety was founded upon a part of Bourgeau\s 

 no. 220, collected "in sylva de la desierta Vieja." According to 

 the sWet-r.hes and snikelets from the soecimen in the Museum of
