incrassata. Racemi breves, terminales, bracteati. Pedicelli bracteolati, pubescentes. 
 Bracteole laneeolats, acuts, tenuiter glanduloso-ciliate. Calyx glaber, lobis 
deltoideo-ovatis acutis. Corolla 2% lin. longa, urceolata, breviter 5-loba. Stamina 
10, inclusa, filamentis a basi attenuatis ciliatis, antheris acutis nee aristatis. 
Ovarium obconicum, 5-loculare, glabrum, loculis 2-3-ovulatis.— Vaccinium, an 
V. floribundum, H. B. & K.?, Oliver, in Trans. Linn. Soc. Ser. II. Bot. ii. (1887) p. 278. 
A small branching shrub, probably of dwarf habit. Branches rather slender, very 
leafy, pubescent with short spreading hairs. Leaves small, petiolate, thick, rigidly 
coriaceous, glabrous; petiole 3-11 lin. long; blade 34-7 lin. long, 2-54 lin. broad, 
varying from lanceolate to elliptic, obtuse or bluntly pointed, rarely acute, crenately 
toothed or entire, with the margins much thickened beneath, and the veins usually 
inconspicuous above, more or less evident beneath. Flowers in short terminal bracteate 
racemes, or aggregated at the apex of the branches.  Pedicels 14-3, rarely 4-5 lin. long, 
pubescent, bracteolate. Bracts and bracteoles similar, 1-13 lin. long, lanceolate, 
acute, or occasionally the bracts are larger and resemble very small leaves, glabrous, 
more or less gland-ciliate. Calyx jointed to the pedicel, with a 5-lobed limb, glabrous ; 
lobes 1 lin. long, deltoid-ovate, acute. Corolla 2? lin. long, urceolate, 5-lobed, 
glabrous; lobes about $ lin. long, broadly ovate, obtuse. Stamens 10, included; 
filaments 1 lin. long, tapering upwards from a broad base, ciliate ; anthers acute but not 
aristate. Ovary obconical, surmounted by a thick ring-like disk, 5-celled, with 2-3 
ovules in each cell, glabrous; style about 12 lin. long; stigma dilated cushion-like. 
Summit of Mount Roraima, 8600 ft, im Thurn, 329, 333; McConnell & Quelch, 19, 
494, 642. 
Allied to F. polystachyum, Benth., but very different in foliage. 
- Besides the above, there is a specimen belonging to this family which is too imperfect 
for identification ; it was collected in the Kotinga Valley, McConnell & Queich, 187.
