198 OPHRYDEJZE. 
Flowers spreading, crowded, about 10 mm. across, floral bract 5 mm. long, broadly 
lanceolate, acuminate, a little shorter than the ovary. Sepals sub-erect, ovate-oblong, 
acute, green. Petals and lip white, slightly tinged with green. Petals as long as 
the sepals, linear-lanceolate, divergent. ip longer than the petals, trifid, deflexed 
from near its base, the margins reflexed; lower portion very thick and with a small 
concavity at the base; midlobe lanceolate, obtuse, nearly as long as the curved 
filiform side lobes. Anther-celis parallel, pollinia obovate-ellipsoid, caudicles very short 
glands discoid, reddish-brown, seated оп the diverging arms of the branched rostellum. 
Stuminodes large, spreading. Stigmas 2, lying beneath the rostellum, obovate, obliquely 
converging downwards and towards the concavity of the lip. Ovary about 6 mm. long 
ovate-oblong, beaked. И. laziflorum Lindl. in Herb. 
Near Mussoorie at an elevation of about 6,500 feet, found growing on oak 
trees, but very rare, Mackinnon (Duthie’s Nos. 22993, 25421). Flowers in August. 
Discovered previously by Sir Joseph Hooker at Senchal in Sikkim at ап elevation 
of 7,000 feet (No. 279). 
A very distinct species, its nearest Indian ally being Н. angustifolium, which it rather closely 
resembles when dried; in fact, it was amongst the specimens of the latter at Kew that a single 
specimen of Hooker's Senchal plant was detected. in Lindley’s Orchid herbarium are two other 
specimens from the same gathering. In the Kew collection of drawings there is a coloured one of 
this Senchal plant received from the Caleutta gardens in 1876. It agrees in all essential particulars 
with the plate here given of H. Mackinnoni. It is smaller and altogether a more delicate plant 
than H. angustifolium, with fewer shorter and broader leaves; the flowering spike also is shorter and 
broader, the petals and lip are white, and the midlobe is much longer. The shape of the ovary 
is also very different.

4. HERMINIUM CONGESTUM Lindl, in Wall Cat. No. 7068. 
Plant 1 to 2 dm. high. Tuber sub-globose, hairy. Lower portion of stem clothed 
with one or two short wide sheaths, Leaves two or three, near the base of the stem, 
x to 10 em. long, narrowly oblong-elliptic or oblanceolate, sub-acute or obtuse. 
Peduncle stout, naked, or with a single linear or leaf-like bract. Spike rather narrow, 
5 to 10 еш. long, many- and densely-flowered. Flowers green, minute, decurved ; 
floral  Бгасё ovate, acute, much shorter than the beaked ovary. Sepals sub-equal, obtuse, 
the dorsal. broadly ovate; lateral pair narrower, slightly spreading, oblong and acute. 
Petals a little longer than the sepals, obliquely lanceolate, acute. Lip longer than 
the sepals, fleshy, triangularly ovate-lanceolate, obtuse; side lobes very narrow, cranu- 
late, apical lobe entire; upper surface with two small calli at the base: spur saccate. 
sub-globose. Anther-ceils diverging towards the base; pollinia sub-globose, caudicles 
very short, attached obliquely to the horn-like glands. Staminodes elongate, tapering 
at the ends, Stigmas two, placed behind the caudicles of the pollinia and above the 
entrance to the spur. Lindl. Gen. and Sp. Orch. 305; in Journ. Linn. Soc. iii, 43;
