Names
LISTROSTACHYS Hookeri Rolfe [family ORCHIDACEAE]
Angræcum arcuatum Hook. f. [family ], in Journ Linn. Soc. vii. 220 (not of Lindl.).
Information
Stems short, 4–5 in. long. Leaves linear-oblong, 3–5 in. long, 6–10 lin. broad; apex very shortly bilobed; lobes slightly unequal, rounded. Racemes 2 1/2–4 in. long, 4–10-flowered, secund. Bracts broadly ovate, subobtuse, 3–5 lin. long. Pedicels 6–9 lin. long. Sepals lanceolate, acuminate, 6–7 lin. long, recurved. Petals similar to but slightly smaller than the sepals. Lip acuminate from a broader triangular-ovate base, recurved, nearly as long as the petals; spur rather stout, nearly straight, 1 1/4–1 1/2 in. long. Column very stout, 3/4 lin. long; rostellum linear, 1 1/2 lin. long, deflexed into the spur; gland linear, 1 1/4 lin. long; stipites distinct, 3/4 lin. long.
Distribution
Upper Guinea Cameroon Mountains, 4000–6000 ft. Mann, 2114! Johnston, 101!
Notes
Near the South African L. arcuata, Reichb. f., with which it has been confused, but with a nearly straight spur and thinner leaves. Fine fruiting specimens from near Sulimania, Sierra Leone, Scott-Elliot, 5282! and near Sutah, Ashanti, Cummins, 37! apparently represent distinct species of this affinity, but cannot be identified without flowers.
