40. citr6smuin, Lindl. Fig: 1513. Pseudobulbs subro- 

 tund, compressed, smooth, 1-lvd.: Ivs. oblong, obtuse, 

 thick, somewhat shorter than the raceme: scape pen- 

 dent, 8-12-fld. : fls. large and full in outline, 3 in. across,

Var. album, Veitch. Fls. white, except the yellow 

 claw of the labellum. Gn. 24:413. Var. ros611um, Le- 

 maire. Fls. rose-colored, except the yellow claw of the

 the labellum deep rose. Var. punctatum, Veitch. Fls.

41. pulch611um, Batem. Pseudobulbs oblong, com- 

 pressed, 2-lvd. : Ivs. grass-like, rather stiff or rigid, 

 9-12 in. long: scape weak, 6-7-fld. : fls. white, except the 

 yellow crest of the labellum; sepals ovate, acute; petals 

 obovate, acute, somewhat 

 undulate; lateral lobes of 

 the labellum triangular, 

 middle lobe oblong, sub-

 Guatemala. B. M. 4104. 

 B.R.27 :48. Easily grown, 

 and never fails to blos- 

 som. The flower-spikes 

 suggest the lily-of-the-yal- 

 ley. Fragrant. Var. majus, 

 Hort. More robust than 

 the type, with larger fls. 

 Var. grandifldrum is 

 listed. 



42. gertoni,Lindl. Like 

 O. pulchellum, but with 

 the fls. only half as large: 

 labellum acute, not almost 

 truncate, excavated at 

 the base and with 2 teeth 

 inflexed over the excava- 

 tion. Guatemala. This is 

 probably only a form of O. pulchellum. 



43. Rossii, Lindl. Pseudobulbs small, much com- 

 pressed, 1-lvd.: Ivs. about 6 in. long: raceme about as 

 long as the Ivs., 2-5-fld. : fls. 2-3 in. in diameter; sepals 

 lanceolate, acuminate, cream-colored to greenish yellow, 

 with short bars of dark brown; petals white, with a few 

 brown spots at base, oblong, obtuse, revolute; labellum 

 round-ovate, emarginate, undulate, pure white, except 

 the yellow claw. Winter. Mex. F.C. 3:129. B.R. 

 25:48. B. 5:222. Gn. 19, p. 306; 28:507. F.S. 20:2110.- 

 This is an extremely variable species, and probably in- 

 cludes the forms cultivated as O, JEhrenbergii and O. 

 Dawsonianum, which are united with this species by 

 some authors. The name majus has been applied to 

 several varieties. Probably I.H. 1:30 (as O. Ehren- 

 bercfii) and F.S. 8:846 (as O.Ehrenbergii = O. apterum, 

 ex-Index Kewensis) also belong here. 



Var. rubescens, Carr. (O. Rossii majus rubescens, 

 Hort.). Fls. large; petals clear rose, with dark brown 

 spots at the base. R.H. 1886:492. Gn. 28:507; 39, p. 

 345. G.C. II. 21:345. 



44. Dawsonianum, Reichb. f. (O. 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. Mexico. G.C. 1865:1226; 11.25:469. F.S. 17, p. 76. 



SECTION V. 



45. ISdwardi, Reichb. f . Lvs. 2 ft. long, strap-shaped : 

 panicle suberect, curved, 2 ft. long, the rachis bearing 

 many horizontal branches covered with many rather 

 small dark purple flowers : sepals and petals oblong 

 to ovate-obtuse, reflexed and wavy; labellum tongue- 

 shaped, obscurely lobed, with a prominent yellow lobu- 

 late callus on the disk. Spring. Ecuador. B.M. 6771. 

 A distinct plant, easily cultivated. 



Supplementary list of synonyms and imperfectly known 

 kinds: O. Arnoldianum. O. blandum, Reichb. f. Sepals and 

 petals cuneate-lanceolate, acuminate, pale yellowish white, 

 spotted with crimson-brown; labellum ovate, acuminate, 

 crisp. Resembling O. nseveum, with the labellum much 

 broader. Winter and spring. Colombia. Fls. in a nodding 

 raceme, creamy white, spotted with reddish purple; labellum 

 white, spotted like the petals and stained with yellow at the 

 base. O. Dawianum. Perhaps a misprint for Dawsonianum
