and numerous densely imbricated bracts; bracts of the 
glomerules fibrous-membranaceous, disintegrating into 
numerous fibres. Flowers small, with short stout ovaries 
which are nearly concealed by the bracts of the inflo- 
rescence, the floral segments very fleshy-thickened and 
connivent. Dorsal sepal broadly ovate-elliptic, obtuse, 
concave, about 8 mm. long and 5.5 mm. wide below the 
middle. Lateral sepals obliquely triangular, obtuse, con- 
‘ave, about 8 mm. long and 7 mm. wide across the base, 
adnate to the column-foot to form a prominent mentum. 
Petals oblong-elliptic, broadly rounded at the apex, slight- 
ly oblique, about 9 mm. long and 4.5 mm. wide. Lip 
densely covered with minute papillae, subarticulated to 
the column-foot, strongly arcuate-recurved in natural 
position with the lower half of the margins upturned to 
form a channel, broadly obovate-flabellate in natural po- 
sition, deeply emarginate with the lobules rounded, ob- 
cordate-subquadrate when spread out, about 9 mm. long 
and 7 mm. wide near the apex. Column short, stout, less 
than 3.5 mm. long, 3-lobulate at the apex, with the mid- 
dle lobule incurved over the anther, produced at the base 
into a broad elongated foot; column-foot as long as or 
longer than the column, strongly sulcate, about 8.5 mm. 
long, forming with the column a deep saddle. Capsule 
suborbicular-ellipsoidal, about 1 cm. long. 
The large glomerules at once distinguish this species 
from P.striata, its nearest ally. The smooth, not verru- 
cose, leaf-sheaths also distinguish it from that species. 
Although the lip is not unlike that of some forms of P. 
striata, the floral segments are much fleshy-thickened 
rather than thin. The leaves are usually larger than those 
of P. striata. 
Ponera glomerata has been found only in Mexico and 
Guatemala.
