MOUNT ROKAIMA IN BRITISH GUIANA. 1)5 



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, '-V-V1 ; McConnell & Quelch, 104, 047- 

 Allied to Gauliheria cordifolia, 11. B. & K., and G. vestita, Henth., but differing from 

 both in the scabrid upper surface of the leaves, the stouter gland-tipped seta? which 

 clothe it. and by the obtuse, not aristate anthers. 



Ledotiiamnus sessilielorus, N. E. Brown, sp. n. Fraticulus nanus, ericoideus. Eolia 

 verticillata, 3-na vel 4-na ad nodos posita, imbricata, brevissime petiolata, linearia 

 vel lineari-lanceolata, acuta, minute puberula. Flores solitarii, termiuales, sessiles. 

 Sepala 7 vel 6, anguste lanceolata, acuta, puberula vel subglabra, ciliata. Petala 

 7 vel 6, oblonga obtusa, glabra. Stamina 7 vel 6, filanientis quain 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 tin- 

 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, lh-2h lin. long, |-§ 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, f-lj in. diam., sessile, surrounded by a few bracts that are intermediate 

 in character between the sepals and leaves. Sepals 7 or occasionally 0, spreading, *>— 1 A 

 lin. long, §-f 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 3J-4i lin. long, gradually dilated towards the base; 

 anthers 1^ lin. long, oblong, obtuse. Ovary subglobose or ovoid, granulate-rugose, 5-8- 

 celled, with a stout style 1J-1^ lin. long, slightly dilated at the apex into a funnel- 

 shaped minutely 5-8-lobed stigma. Capsule sessile, 2-2/, lin. diam., 5-8-valved, 

 granulate.

Var. glaber, N. E. Brown, var. n. Folia et sepala glabra, ciliata. 



Leaves and sepals glabrous, ciliate.

Mount Koraima, on the upper part of the Ledge and on the summit, Ln Thurn, 308 ; 

 McConnell 8f Quelch, 99. 



This plant is very distinct from L. guyanensis, Meissn., with which it has been 

 associated by Oliver, differing not only by its smaller size and smaller leayes, but more 

 especially by its sessile flowers and the long filaments of the stamens, ln L. guyanensis 

 the flowers have pedicels ^— § in. long covered with gland-tipped hairs, and the filaments 

 of the stamens are only about 1 lin. long and shorter than the anthers.
