26. cordatum, Lindl. Pseudobulbs oblong, 1-lvd.: 

 Ivs. oblong, acute, 6-8 in. long : fls. large and handsome, 

 with the sepals and petals yellowish green, richly 

 blotched with brown; labellum cordate, acuminate, 

 subcrenate, white, with a purplish crest at base and 

 spotted with brown on the limb; sepals lance-linear, 

 acuminate; petals broader and longer, undulate. Mex. 

 B.M. 4878 (as 0. maculatum). I.H. 26:355. P.M. 13: 

 147. Gn. 27:46. F.C. 3:100. St. 2-3 ft, high: few 

 or many-fid . 



27. bictoniense, Lindl. Pseudobulbs oblong, 2-3 in. 

 long, 2-3-lvd.: Ivs. 1 ft. long, ensiform, undulate, 

 spreading: raceme 3 ft. long; fls. IK in. across; sepals

 Autumn. Guatemala. B.M. 3812 (as Zygopetalum 

 africanuni). This was the first odontoglossum to reach 

 England in a living state. It is free-flowering, but not 

 so good as plants subsequently intro. Var. album, 

 Hort. Like the type, but labellum pure white instead of 

 wine-red; sepals and petals brown. I.H. 19:91. 



Var. splendens, Ch. Lena. Labellum rose-lilac; other 

 segms. spotted. Seems to be like the type, with more 

 pronounced color. I.H. 12:449. 



28. hastilabium, Lindl. Lvs. linear-oblong: scape 

 lJ^-2 ft.; bracts long, deciduous; fls. numerous, large, 

 handsome, varied with pale green, purple and white, 

 fragrant; sepals and petals spreading, lanceolate, very 

 acuminate, pale green, with transverse purple dots and 

 lines; labellum large, the lateral lobes forming 2 horns 

 at base, the central one with a purple, crested claw, and 

 orbicular-ovate, white, acute blade; column slender, 

 winged, purple. Summer. Colombia. B.M. 4272.

29. ramosissimum, Lindl. Lvs. linear-oblong, acute, 

 1 ft. long: panicle much branched and many-fld., 2 ft. 

 long; fls. 2 in. across, white, spotted with pale purple 

 or violet; sepals and petals very undulate, narrowly 

 ligulate, the latter wider; labellum rhomboid, acumi-

 April. Colombia. J.H. III. 29:77. I.H. 40:170 (var. 

 coeleste, Lind. & Rod.). A distinct and beautiful plant 

 whose fls. have been likened to large spiders. 



30. naevium, Lindl. & Paxt. Pseudobulbs oblong: 

 Ivs. thin, lanceolate: panicle erect, arching, much 

 branched, bearing numerous star-shaped fls.; sepals 

 and petals 2 in. long, narrowly lanceolate, beautifully 

 crenate-undulate, white, profusely spotted with rose- 

 purple; labellum shaped nearly like the petals, shorter 

 and broader, with 2 large crests on the yellow base.

 pressed, 2-3 in. long: Ivs. 4-6 in. long, linear-ensiform, 

 leathery: panicle often over 2 ft. long, drooping, or 

 inclined; fls. 3 in. across, snow-white, blotched with 

 crimson or brown, base of the labellum yellow, with 

 brown lines at the sides; sepals narrowly lanceolate, 

 ending in long, curved points; petals wider; labellum 

 two-thirds the length of the petals, with 2 ciliate lateral 

 lobes and a narrow acuminate middle lobe. April, 

 May. Ecuador, Peru. B.M. 6317. I.H. 25:301. Gt. 

 41:1383. Gn. 9, p. 401; 16, p. 19. G.C. II. 5:501, 503; 



9: 181; 25: 12. F.M. 1876: 222. This species sometimes 

 produces stout few-fld. sts., which should be cut to 

 save the vigor of the plant. 



32. Ruckerianum, Reichb. f. Related to 0. crispum: 

 sepals and petals lanceolate, acute, creamy white, bor- 

 dered with violet and spotted with brown, waved; 

 labellum rather narrow, oblong, angular-lobed on each 

 side of the base, yellow at base, with few chestnut- 

 brown blotches; callus rhomboid serrate. Colombia.

 long, diffuse, bearing numerous white, membranaceous 

 fls. slightly tinged with rose; sepals ovate-oblong, slightly 

 undulate; petals similar but much wider; labellum 

 cordate-oblong, pandurate, with a yellow fimbriate 

 crest and a few rose-colored spots. Spring. Colombia.

 285; 36:307. A fine species producing numerous large, 

 erect panicles. Var. Veitchianum, Reichb. f. Like the 

 type, but the parts of the fl. have large, crimson-pur- 

 ple spots. Gn. 26:112. 



34. crispum, Lindl. (0. Bluntii. Reichb. f. 0. Alex- 

 andra, Batem.). Figs. 2562 and 2563. Pseudobulbs 

 ovate, co m- 



pressed, about 3

 rather short, but 

 attaining a length 

 of 2 1 A ft., with few 

 short branches 

 and crowded fls.;

 ously spotted with

 introduction, this species has probably more than 100 

 named varieties. Many besides those cited have been 

 figured in horticultural and botanical works. Very few 

 varieties are found in American trade lists, but some 

 of the most distinct are given below: 



Var. Andersonianum, Hort. (O. Andersonianum, 

 Reichb. f.). Fls. creamy white, with broad, longitudinal 

 bands of cinnamon. F.M. 1872:45. G.C. II. 24:680, 

 681; III. 17:739. G.W. 13, p. 619. Listed in Amer. 



Var. apiatum, Ballantyne. Fls. very large; sepals 

 and petals laciniate on the edges, white, with rich choco- 

 late-brown blotches. G.C. III. 15:375. 



Var. Ashworthianum, O'Brien. Fls. almost entirely 

 rose-purple, with white margins and a few white marks 

 on the sepals and petals. G.C. III. 19:197. 



Var. Codksoniae, Hort. Fls. 4 in. across, the segms. 

 fringed and heavily tinged with purple on back, the 

 face pure white around the column, the margins white, 

 tinged purple in places, the segms. with a large central
