SYNOPSIS OF THE GENERA. 
the base. Glands of the stalks of the pollen masses 
naked, distinct. 
6. O'purys, [Page 1116.] Sepals spreading, coloured, or 
herbaceous, petals much smaller than the sepals, and 
mostly coloured, /ép without a spur, convex, more or less 
lobed. Glands of the stalks of the pollen masses in 
separate pouches, each mass deeply divided, into nume- 
rous angular lobes. 
TrisE 2. Pollen masses, not stalked, simple, consisting of 
granules, in a slight state of cohesion. Anthers parallel 
with the stigma. (NreotTiex, Lindley). 
7. Goopye'ra, [Page 1119.] Sepals ovate, spreading. 
Petals erect, lip entire, remarkably concave beneath, 
. enclosed by the lateral sepals. Column taper, dis- 
tinct, with two teeth at the apex. Stigma in front 
oblique. Anthers two celled. Pollen masses sessile. 
8. Nreorr'ra, [Page 1120.] Sepals and petals brown, sub- 
campanulate, /ip not spurred, dependent, two lobed, 
concave at the base. Column taper, erect, four times 
as long as the stigma. Stigma two lipped. Anther 
naked, terminal, free, attached to the back of the 
stigma. 
9. Sprran’THES, [Page 1121.] Sepals and petals coloured, 
converging, parallel with the lip. Zzp included within 
the lateral segments, entire, unguiculate, with two fleshy 
projections at the base. Column taper, club-shaped, 
free, with two teeth at the apex. Stigma prominent, 
rostrate. 
10. Listse'ra, [Page 1122.|] Sepals and petals herbaceous, 
connivent, /ip two lobed, dependent, not spurred. 
Column taper, erect, much shorter than the stigma. 
Stigma plane, ovate. Anther covered by a hood, pro- 
ceeding from the back of the column. Pollen fari- 
naceous. 
Tribe 3. Pollen masses, not sialked, simple, consisting of 
granules, in a slight state of cohesion. Anthers terminal, 
like a lid, persistent. (ARtTHUSE®, Lindley.) 
11. Eprpac’t1s, [Page 1123.] Sepals and petals spreading 
or converging, more or less coloured, /ip embracing the
