Habenaria] III, ORCHIDEA. 13 
‘its determination must therefore be doubtful; but No. 743, of which we 
have in Herb. Mus. Brit. an excellent sketch and a single opening flower, 
is identical with No. 721 (H. Welwitschii Rchb. £.). Krinzlin places 
the two species in different sections (3 and 4 respectively), but there is 
very little distinction between the sections. 
2. H. tentaculigera Rchb. f. in Flora 1867, p. 101; Durand & 
Schinz, Z.c., p. 86; Kriinzl., J.c., p. 205. 
Huiiia.—Older tubers hollow and chambered by transverse lamella. 
Stem and rhachis of spike angled. Leaves fleshy, herbaceous-green, 
carinate ; bracts and flower herbaceous-green, the lip only somewhat 
yellowish. Ovary deeply furrowed. Here and there in lofty thickets 
at+5200 ft., Morro de Lopollo. In bud and flower Feb. 1860. A 
poorer few-flowered form, on thicket-grown sandy wooded hills between 
Ohai and Gambos. In fl. March 1860. No. 716. 
3. H. robusta Welw. ex Rehb. f., /.c., p. 102; Durand & Schinz, 
ic. p. 85; Krinzl., lc, p. 216. 
Punco AnponGo.—A herb 4 ft. high or more, stem and leaves sub- 
glaucous, flowers whitish-green, with a strong goat-like smell. Rather 
rare and sporadic in wooded thickets Sobato de Quibanga. A unique 
specimen ; in fl. Jan. 1857. No. 695. 
4. H. huillensis Rehb. f. in Flora 1865, p. 179; Durand & 
Schinz, l.c., Kriinzl., l.c., p. 220. 
Hoitia.—A herb 13 ft. high with habit of Platanthera, with two 
tubers, one stalked; stem angled, leaves sheathing, herbaceous-green, 
perianth-segments and long spur all greenish-yellow. Here and there 
in marshy herb-grown places near streams in the way from Lake 
Ivantala to Quilongulo ; in fl. Feb. 1860. No. 724a. Here and there 
in short-grassed rather damp pastures near Catumba, end of March 
1860. No. 7245. Flowers white, bracts slightly greenish. In wooded 
meadows between Monino and Ivantala April 1860. No. 724c. 
The flowers of No. 724c are a little larger and the anterior division 
of the petals is broader in proportion than in the other two specimens 
5. H. anaphysema Rchb. f. in Flora 1867, p. 101; Durand & 
Schinz, i.c., p. 73; Kranzl., lc., p. 225. 
Hvrtia.—Leaves and herbaceous-green stem as in H. Welwitschii, 
but leaves more flaccid, and almost subulate-acuminate. Outer 
perianth-segments deep green, with yellowish-red markings, inner 
greenish-yellow. Spur filiform descending, abruptly club-shaped at 
the end, and reflexed. Sporadic in rather damp thicket-grown pastures 
between Humpata and Nene. [No date.] No. '744. Represented in 
Herb. Mus. Brit. by a sketch only, but evidently very near H. Wel- 
witschii, of which Welwitsch suggests it may be a variety. 
6. H. occultans Welw. ex Rchb. f. in Flora 1865, p. 178 ; Durand 
& Schinz, l.c., p. 82; Kranzl., dec. p. 243. 
Huriita.—A herb with two tubers, stem 14 to 2 ft. long, erect, 
angled, leaves sheathing, nerves very prominent beneath. Flowers 
long-stalked, stalks more or less hidden within the leaf-sheaths ; ovary 
trigonous, green ; perianth yellow-greenish, lip-lobes sulphur-colour, the 
lateral ones deeply fimbriated, Spur 3 to 43 in., hidden behind the 
bracts of the lower flowers. Plentiful but in one locality only, in 
marshy places by the stream at Humpata, and very rare near Lopollo. 
Dec. and Jan. 1859-60. No. 737.
