MOUNT RORAIMA IN BRITISH GUIANA. 45 
long, oblong, obtuse, shortly bifid at the apex, but not in the least produced into awns 
or tubes, opening by longitudinal slits nearly to the base. Ovary depressed, 5-lobed, 
pubescent ; style included, rather stout, glabrous; stigma simple, not enlarged. Capsule 
depressed, 5-angled, pubescent. 
Summit of Mount Roraima, 8600 ft., im Thurn, 332 ; McConnell & Quelch, 104, 647. 
Allied to Gaultheria cordifolia, H. B. & K., and G. vestita, Benth., but differing from 
both in the scabrid upper surface of the leaves, the stouter gland-tipped sete which 
clothe it, and by the obtuse, not aristate anthers. 
LEDOTHAMNUS SESSILIFLORUS, N. E. Brown, sp. n. Fruticulus nanus, ericoideus. Folia 
vertieillata, 3-na vel 4-na ad nodos posita, imbricata, brevissime petiolata, linearia 
vel lineari-lanceolata, acuta, minute puberula. Flores solitarii, terminales, sessiles. 
Sepala 7 vel 6, anguste lanceolata, acuta, puberula vel subglabra, ciliata. Petala 
7 vel 6, oblonga obtusa, glabra. Stamina 7 vel 6, filamentis quam antheris multo 
longioribus. Discus nullus. Ovarium subglobosum vel ovoideum, granulosum, 5-8- 
loculare ; stylus crassus; stigma subinfundibuliforme, minute 5-8-lobulatum. 
A dwarf shrublet 4-8 in. high. Stems erect, simple or branched, densely leafy to the 
apex, at first minutely puberulous, becoming glabrous, and rough from the persistent 
scars of the fallen leaves. Leaves resembling those of an Erica, in densely crowded 
whorls of 3-4, ascending, imbricating, 14—24 lin. long, 1-3 lin. broad, linear or narrowly 
linear-lanceolate, acute, narrowed at the base into a very short petiole, thick, flat on 
the face, grooved down the back, minutely puberulous, ciliate or entire. Flowers 
terminal, solitary, 2-121 in. diam., sessile, surrounded by a few bracts that are intermediate 
in character between the sepals and leaves. Sepals 7 or occasionally 6, spreading, 3-44 
lin. long, 3-2 lin. broad, narrowly lanceolate, acute, minutely puberulous or subglabrous, 
ciliate. Petals usually 7, very spreading, bright crimson, 5-7 lin. long, 2-3 lin. broad, 
oblong, obtuse, cuneately narrowed at the base, entire, glabrous. Stamens 7 or 6, shorter 
than the petals, glabrous; filaments 34—44 lin. long, gradually dilated towards the base ; 
anthers 14 lin. long, oblong, obtuse. Ovary subglobose or ovoid, granulate-rugose, 5—8- 
celled, with a stout style 14-14 lin. long, slightly dilated at the apex into a funnel- 
shaped minutely 5-8-lobed stigma. Capsule sessile, 2-25 lin. diam., 5-8-valved, 
granulate. :

This plant is very distinct from Z. guyanensis, Meissn., with which it has been 
associated by Oliver, differing not only by its smaller size and smaller leaves, but more 
especially by its sessile flowers and the long filaments of the stamens. In L. guyanensis 
the flowers have pedicels 3-3 in. long covered with gland-tipped hairs, and the filaments 
of the stamens are only about 1 lin. long and shorter than the anthers. :
