1-1 J lin. broad, lanceolate, acuminate. Flowers rather small, pink. 

 Dorsal sepal erect, 3^ lin. long, l|-2 lin. broad, helmet-shaped, dorsally 

 produced into a stout, compressed spur, lJ-2 lin. long, 1^-1 J lin. broad, 

 oblong, obtuse, ascending when in position on the spike, the whole sepal 

 measuring 3j-4 lin. from the apex to the tip of the spur. Lateral 

 sepals deflexed, divergent, 2-2 J lin. long, lJ-1^ lin. broad, obliquely or 

 subfalcately oblong, concave, subacute, with a subulate dorsal apiculus 

 1 lin. long just below the apex. Petals 2-2^ lin. long, rather more 

 than J lin. broad in the lower part, and 1 lin. or more broad at the 

 apex ; lower half oblong, auricled at the base ; apical half obliquely 

 ovate, subobtuse, directed forwards. Lip 2| lin. long, J lin. broad, 

 narrowly oblong, with reflexed or replicate sides, apex obtuse, bent 

 downwards, cuneately narrowed into a short stalk at the base, obtusely 

 keeled down the middle. Anther horizontal, 1 lin. long, suborbicular. 

 Rostellum very short and broad, subtruncate, slightly folded between

Allied to D. equestris, Reichb. f., but readily distinguished by its narr6wer 

 bracts, shorter spur, and long apiculus to the lateral sepals. 



18. D. pulchella, Hochst. ex A. Rich. Fl. Abyss, ii. 301, t. 93. 

 Plant 4-16 in. high, glabrous. Leaves 3-8, scattered, erect, the lower 

 3-3 J in. long, 6-13 lin. broad, varying from lanceolate to elliptic- 

 oblong, acute, the others gradually decreasing upwards. Spike H-4;\ 

 in. long, 7-9 lin. thick, dense. Bracts shorter than flowers or about 

 equal, 5-8 lin. long, ovate-lanceolate, acuminate. Flowers rather 

 small. Dorsal sepal 2J-3 lin. long, 2-4 lin. broad at the mouth, 

 suborbicular or transverse oblong, helmet-shaped ; spur erect or 

 ascending, moderately stout, 2-3 lin. long, J-| lin. broad, slightly 

 compressed, straight, obtuse. Lateral sepals deflexed, divergent, o-3J 

 lin. long, lJ-2 lin. broad, oblong or cuneate-oblong, obtuse, with 

 a compressed dorsal apiculus J-f lin. long just below the apex, margins 

 often reflexed or revolute. Petals 1J-2J lin. long, 1J-1| lin. broad 

 at the apex, somewhat oblong, auricled at the base, dilated at the 

 subtruncate apex ; posterior margin concave ; anterior margin more 

 or less broadly emarginate. Lip 2J-3 lin. long, linear-oblanceolate or 

 spathulate-obovate, obtuse, keeled down the face from the margins 

 being replicate. Anther horizontal. Rostellum bilobed, lobes large and 

 triangular, adnate to the base of the petals. — Walp. Ann. iii, 590;

The flowers vary in colour, in the type (Schimper, 1192) they are whitish or 

 pallid, spotted with dark purple in all parts, whilst Schimper'x 1316 has the lateral 

 sepals and apical part of the lip entirely of a dark purple colour, but there is no 

 structural difference between tliem.
