60 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
acuminate, 3 lin. long, more or less ciliate, trinerved. Lip sessile, 14 lin. long, trilobed ; 
side lobes falcate-oblong, subobtuse, suberect; front lobe reflexed, broadly rounded- 
oblong; dise with a slightly elevated crest between the side lobes. Column broad, 
3 lin. long. 
Roraima range, 3500 ft., McConnell & Quelch, 705.—Fndemic. 
An interesting addition to this small genus, readily distinguished from its allies by 
the short secondary stem, and short tails to the sepals and petals.

Ser. II. Bot. ii. (1887), p. 281; Woolw. Masd. p. 87, t. 34. 
Roraima, at 3500 ft., McConnell & Quelch, 704; Upper slope, im Thurn, 279. 
In the mountains of Colombia, between 2500 and 6500 ft. elevation ; extending along 
the Coast Andes of Venezuela to Caracas, at 6000 to 6500 ft. ; also in Costa Rica. 
Roraima seems to be an outlying station for the species. 
OcroMERIA CONNELLII, Rolfe, sp. n. Caules secundarii elongati. Folia subsessilia, 
oblongo-lanceolata, subobtusa, crasso-coriacea. Flores subfasciculati, mediocres. 
Sepala et petala ovato-lanceolata, subobtusa. Labellum oblongum, subconcavum, 
obtusum vel obscure tridentatum, margine minutissime crenulatum. 
Secondary stems stout, elongate, 4-12 in. long, clothed with four or five tubular 
sheaths 1-14 in. long. Leaf subsessile, thickly coriaceous or somewhat fleshy, oblong- 
lanceolate, subobtuse, 2-4 in. long, 4-10 lin. broad. Flowers few, or produced mostly 
in succession, medium-sized, shortly pedicelled. Sepals and petals ovate-lanceolate, 
subobtuse, 4—6 lin. long. Lip oblong, somewhat concave, obtuse or obscurely tridentate, 
margin minutely crenulate, 3—4 lin. long. Column clavate, 13 lin. long. 
Roraima, summit at 8600 ft., McConnell & Quelch, 700.—Endemice. 
A very distinct species, having stems much longer than the leaves, and flowers 
comparatively large for the genus. It is comparable with O. grandiflora, Lindl., but has 
longer stems, much shorter leaves, and the lip very different in structure. 
OcYroMERIA PARVIFOLIA, Rolfe, sp. n. Czespitesa. Caules secundarii graciles, vaginis 
tubulosis striatis obtecti. Folia lineari-oblonga, subacuta, parva. Flores fasciculati. 
Sepala ovato-oblonga, subobtusa. Petala lineari-oblonga, subobtusa. Labellum 
late deltoideo-trilobum, lobis lateralibus divergentibus anguste triangularibus, 
intermedio breviter et late triangulari obtuso. 
Secondary stems densely tufted, slender, 24-3 in. long, clothed with about five or six 
tubular striate sheaths. Leaves linear-oblong, subacute, }-1} in. long, 1-14 lin. broad, 
base somewhat attenuate. Flowers fasciculate. Pedicels very short. Sepals ovate- 
oblong, subobtuse, 1 lin. long. Petals linear-oblong, subobtuse, 1 lin. long. Lip broadly 
deltoid-triangular, over 4 lin. broad; side lobes narrowly triangular, subobtuse ; front 
lobe broadly triangular, obtuse; disc with a pair of thickened slightly arcuate keels in 
the centre, and a shorter one in front. Column short.
