18. Sbuttleworthii, Reichb. f. A small species, with 

 Ivs. only 2 in. long, on distinct petioles of equal length: 

 peduncles several, 1-fld., sometimes overtopping the 

 Ivs.; fls. large (1 in. across and the tails 2-3 times as

20. triangularis, Lindl. Lvs. oblanceolate: peduncle 

 erect, about 4 in. tall; fls. yellow, marked or spotted 

 with purple, the tails dark crimson; lobes similar, tri- 

 angular-ovate; petals white, the lip spotted with pink

21. Wageneriana, Lind. Very small, neat and attrac- 

 tive, tufted, 2-3 in. high: Ivs. spoon-shaped: pedun- 

 cles equaling or exceeding the Ivs., nearly erect; fls. 

 yellow and crimson-dotted, with slender yellow tails, 

 the upper one inclined backward; lobes broad, cordate 

 or ovate; petals yellow, odd in shape, the lip rhomboid 

 and toothed. Venezuela. B.M. 4921. 



22. Estradae, Reichb. f. Very densely tufted: Ivs.' 

 and petioles 3 in. long, the blade broad, spoon-shaped, 

 and often retuse at the apex: peduncle usually some- 

 what exceeding the Ivs., erect, 1-fld.; fl. of marked col- 

 ors the upper concave lobe yellow at base and violet- 

 purple above, the lateral lobes violet-purple at base and 

 white or straw-colored above; tails filiform, yellow; 

 petals white, very small. Colombia. B.M. 6171. 



23. hieroglyphica, Reichb. f. Lvs. oval or oblong: 

 peduncle short (about 3 in. long); fl. with tube yellow- 

 ish at bottom, becoming whitish, marked with crim- 

 son; lobes triangular-ovate, all with long tails, the tail 

 of the dorsal lobe hanging forward and marked with 

 purple at its base; petals yellow. June. Colombia. 



24. elephanticeps, Reichb. f. An odd species: Ivs. 

 broad-spat ulate, obtuse: peduncles 1 ft. long, erect; 

 fl. single, parti-colored the dorsal or upper lobe light 

 yellow, the lateral ones ribbed and crimson; calyx- 

 tube gibbous at the base below, all of them gradually 

 produced into stout yellow tails (one of them often 

 crimson), arranged so as to suggest the tusks and 

 raised trunk of an elephant (whence the specific name). 

 Colombia. F.S. 10:997. B.M. 7824. C.O. 10. Var. 

 pachysepala, Reichb. f. (M. Mooreana, Reichb. f.), has
