DR. LINDLEY ON WEST AFRICAN TROPICAL ORCHIDS. 139 
AMPHORCHIS, Thouars. 
l. A. OCCIDENTALIS ; undique tomentosa, folio unico (variegato) ob- 
longo acuto basi cucullato, scapo bivaginato, spica elongata multiflora, 
petalis glabris truncatis 2-3-dentatis, labello cuneato apice 3-dentato 
supra carinato, calcare filiformi subclavato dorsali supra labellum cur- 
vato. 
“ Flowers orange. Leaves marked like Anectochilus. But one speci- 
men seen, in a ravine near Jeba Nupe." (1487) Barter. 
This species confirms Prof. Blume's opinion (Mus. Lugd. Bot. 
ii. 190) that the genus Amphorchis should be distinguished from 
Cynorchis. lts peculiar character consists in the anther being 
inverted (not horizontal) as in so many Cape Orchids. The plant 
now described looks like a tomentose state of Amphorchis calcarata, 
but is totally different in its petals, lip, and spur. 
HABENARIA, W. 
1. H. PALUDOsA ; (§ petalis labelloque integerrimis) caule gracili stricto 
subbifloro folioso, folio infimo lanceolato cucullato superioribus 4 
distantibus sensim angustatis setaceo-acuminatis, bracteis cucullatis, 
sepalis lineari-lanceolatis supremo c. petalis conformibus galeatis, 
labello lineari-spathulato calcare lineari sepalis longiore, (anthera 
apiculata basibus loculorum clavatis truncatis breviore, appendice 
laterali setacea, processibus ovatis, rostello parvo subulato libero). 
“Terrestrial. Flowers deep orange. Swamps.” Loin Nupe. (1479) 
Barter. 
The habit of this is the same as that of Bonatea pratensis, to 
which genus it would be referred, if the genus Bonatea could be 
retained, which is certainly not the case. The stem is from a foot 
to 14 inches high. 
2. H. STENOCHILA ; ($ petalis labelloque integerrimis) caule folioso, 
foliis 5 oblongo-lanceolatis setaceo-acuminatis in bracteis ovario lon- 
gioribus transeuntibus, spica oblonga multiflora, sepalis lateralibus 
semiovatis obtusis dorsali petalisque ovato-linearibus multo majoribus, 
labello lineari, calcare filiformi arcuato ovario duplo longiore apice 
bidentato, (anthers basibus angustis ascendentibus, appendice laterali 
obsoleta, processibus filiformibus elongatis). 
* Flowers white, fragrant. Prince’s Island.” (1995) Barter. 
Near H. candida, but the leaves are broader, the petals and lip 
very much narrower, and the tip of the spur is not bidentate as in 
that species. 
3. H. MACRANDRaA ; (§ petalis indivisis, labelli tripartiti laciniis late- 
ralibus setaceis) foliis lanceolatis acutissimis petiolatis caule duplo
