Har.—Tenasserm™ ; at Moulmein, Parish. 
Stem as thick as the little finger, somewhat. compressed, green, rooting below the 
leaves. Leaves 8—6 by 2—1 in., bright green, smooth, deeply channelled, sides convex. 
Scape 6—10 in., as thick as a swan's quill, green; sheaths 1 in. long, white; panicle 18 
in. long, stiff, branches distant, spreading, 6—10 ft. long; bracts at the bases of the 
branches 3 in., of the flower 2 in.; pedicels with ovary 3—3 in. Lateral sepals and petals 
widely spreading, subfaleate. Horns of column suberect, cylindric, slightly decurved. 
Anther subquadrate, retuse, crested with hair, contracted at the sides, 
As I heve stated in the Flora of British India in the notes under Trichoglottis, I think that 
Bentham erred in suppressing this genus in the Genera Plantarum, and that taking Blume’s 7. retusa 
(Bijdr. 360, Tabellen fig. viii) as the type, it is well distinguished by the long narrow processes at the 
base of the lip and its hairiness, which suggested the generic name. Kurz’s T. quadricornuta from 
the Nicobar Isds., judging from his figure and description, generically well accords with 7. retusa and 
T. Dawsoniana, as does T. fasciata, of Manilla, of which there is a fine drawing in the Calcutta Herbarium. 
The pollinia of T. Dawsoniana are large, globose, with short slender straps ; not as represented at 
fig. 5, which is probably imperfect or undeveloped. I also find the sepals and petals in the dried 
specimens to have each a cusp beneath the apex, a feature not represented in the drawing, which 
is inscribed * Renanthera from Moulmein, 12-5-70," (the date no doubt of its flowering in the Calcutta 
Botanical Garden). 0 جج‎ : : |
