 Mex. F. C. 3:129. B.R. 

 25:48. Gn. 19, p. 306; 28: 

 226. F.S. 20:2110. This is 

 an extremely variable 

 species, and probably in- 

 cludes the forms cult, as 

 0. Ehrenbergii and 0. Daw- 

 sonianum, which are united 

 with this species by some 

 authors. The name majus 

 has been applied to several 

 varieties. Probably I.H. 1 : 

 30 (as 0. Ehrenbergii) and 

 F.S. 8 : 846 (as 0. Ehrenbergii 

 =O. apterum, ex-Index 

 Kewensis) also belong here.

 Rossii majus rubescens,

 clear rose, with dark brown 

 spots at the base. R.H. 

 1886:492. Gn. 28:226; 39, p. 345. G.C. II. 21:345. 



44. Dawsonianum, Reichb. f. (0. Ehrenbergii, Hort., 

 not Link, Klotzsch & Otto). Raceme few-fld.; sepals 

 lanceolate, subacute, rose-colored, blotched with crim- 

 son to the apex; petals oblong, acute, pure rose; label- 

 lum broadly ovate to subrotund, crenulate; apex retuse, 

 colored like the sepals; callosity with 2 teeth at the 

 apex. Mex. G.C. 1865:1226; II. 25:469. F.S. 17, p. 76.
