34 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
diam., cylindric, 5-grooved, slightly enlarged and densely hairy inside at the throat 
around the anthers; lobes spreading or recurved, 1-2 in. long, 2-6 lin. broad, linear- 
lanceolate or oblong, acute, glabrous, contorted in the bud. Stamens 5, included, 
inserted in the throat of the corolla-tube ; filaments about 24 lin. long ; anthers 3-34 lin. 
long, dorsifixed, with a rather long and broad attachment to the filaments, linear, acute, 
bifid at the base, glabrous. Ovary 24-3 lin. long, stoutly obconical, 2-celled ; style about 
as long as the corolla-tube, or shorter than the anthers or rarely exserted, glabrous ; 
stigma of two oblong obtuse lobes about 1 lin. long. Ovules numerous, flattened, on 
broad placentas that are peltately attached along their middle by a very short narrow 
plate to the septum. Fruit not seen. 
Summit of Mount Roraima, 8600 ft., McConnell & Quelch, 100, 505, 653. 
The variation in the length of the style would seem to imply that the flowers are 
heterostyled, but it may be due to a lengthening at various periods of development. 
'The stems in the figure on Plate 5 are not represented of sufficient stoutness.

DIDYMOCHLAMYS CoNNELLII, N. E. Brown, sp. n. (Plate 5, figs. 1-9.) Folia alterna, 
oblique oblanceolata, subabrupte acuta, glabra. Bracteze exteriores suborbiculares, 
brevissime cuspidatz. Corolle tubus supra medium ampliatus, ore contractus; 
lobi infra medium bilobulati lobulis lineari-oblongis undulatis subtortis. 
A small herb, with a simple stem 11-6 in. long. Leaves alternate, distichous, 1—14 in. 
long, including the very short petiole, 24—44 lin. broad, obliquely or subfaleately 
oblanceolate, acute or rounded in at the apex to a very short cuspidate point, tapering 
from above the middle to an unequal base, the upper side of which is very narrow and 
acute, and the lower side broadly rounded or subtruncate, glabrous on both sides; under 
surface pale, densely covered with large stomata, which appear as whitish dots under a 
lens; stipule solitary, 3-4 lin. long, linear, acuminate, glabrous. Peduncle terminal, 
about ł in. long, bearing two suborbicular, apiculate, glabrous bracts, about 4 in. in 
length and breadth, enclosing 2 (or more?) shortly pedicellate flowers and 1 (or more ?) 
linear acute bracteole. Calyx-lobes slightly unequal, 2-1 lin. long, lanceolate, acute, 
erect, glabrous. Corolla-tube about 3 in. long, probably somewhat compressed, dilated a 
little above the middle, then narrowed to the mouth, glabrous, with the exception of a 
ring of hairs inside near the base; lobes divided to slightly below the middle into two 
diverging, linear-oblong, obtuse, undulated and somewhat twisted lobules 14 lin. long 
and rather more than j lin. broad, the basal entire part being about 1 lin. long and 
broad, deltoid-ovate, slightly concave, with a minute, obtuse, incurved point at the apex 
between the lobules. Stamens 5, included, inserted below the middle of the corolla-tube, 
unequal, 2 longer than the rest and inserted higher up, having on one side a pair and on 
the other side one of the shorter stamens alternating with them; filaments glabrous,
