CONSPECTUS TABULARUM. j 69 
Descr.—Root turnip-shaped, perennial. Stems herbaceous, annual, 
numerous, 6-8 inches high, forked or oppositely much branched, either 
bare of leaves or furnished with subdistant pairs. eaves 1-3 inch 
long, scarcely 1 line wide, obtuse or mucronate, scaberulous, especially 
on the under side, narrowed toward the base. Flowers in axillary 
pairs, on very short pedicels, brownish purple. The lobes of the corolla 
are 4-5 times as long as the tube, ovate at base, with reflexed sinuses, 
and produced into a long, linear point ; they cohere at the apex. Corona 
staminea double, the 5 outer lobes, alternating with the stamens, longest, 
deeply and sharply bifid; the 5 inner, opposite the stamens, incumbent, 
oblong, obtuse. Between each stamen are two small teeth (the margins 
of the confluent filaments). Follicles glabrous, 24-3 inches long. 
“The large flat root is eaten by the Dutch inhabitants, and much 
esteemed as a preserve, under the name, ‘ Aalkowes,’” Mrs. Barber. 
Except in the doubling of the corona, this curious plant does not greatly 
differ from Brachystelma, to which genus I refer it, under the subgeneric 
name Dichaelia,

XCIV. PTERYGODIUM VENOSUM, Lindl. ( Orchidea.) 
P. venosum: foliis lineari-lanceolatis convolutis caulem vestienti- 
bus, spicd densé cylindraced, sepalis ellipticis concavis subsequalibus, 
petalis cuneatis serratis sepalis longioribus, labello subrotundo-cordato 
serrato, appendice minimo labello adnato excavato, rostello biauriculato 
auriculis lanceolatis obtusiusculis reflexis—Lindl. Sp. Orch. p. 367. 
Hazs.—Cape, Villet, in Hb. Lindl. On the Winterhoek, Tulbagh, at 3000 ft., Dr. 
Pappe! Nov. (Herb. T. C. D., Hook., Lindl.) 
Descr.—Stem 6-12 inches high, or rather more, densely clothed 
throughout with leaves, and ending in a long, dense spike of sweet- 
scented flowers. eaves linear lanceolate, attenuate, involute, the 
lower somewhat sheathing, the upper amplexicaul, turning black in dry- 
ing. Flowers very numerous. Bracts erect, longer than the ovary. 
Sepals reflexed, the medial rather narrower than the lateral, but equally 
long, all concave, elliptic-oblong. Petals broadly cuneate or flabelli- 
form, coarsely and bluntly indented. Labellum broader than long, cor- 
date at base, bluntly toothed. odes of the rostellum resembling asses’ 
ears, rising conspicuously between the petals. 
A very rare species, existing in few herbaria, and not found by 
either Ecklon or Drege. I am indebted to Dr. Pappe for well-dried 
specimens, from one of which our figure has been prepared, The spike 
is sometimes longer and more densely flowered than here shown.
