42 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
tomentose, bearing a few small leaf-like bracts at the base of the very short branches 
of the corymb. Heads sessile, densely crowded, about 4 lin. long, 1-flowered. Involucre 
cylindrie-conical, with 12-16 spirally imbricating scales, the innermost about 34 lin. 
long, 1-1 lin. broad, narrowly lanceolate obtuse, glabrous, the outer gradually shorter 
and more and more ovate, and more or less tomentose on the back. Floret not exceeding 
the involuere (?), hermaphrodite. Corolla regular, very deeply 5-lobed, glabrous, the 
lobes about 21 lin. long, linear, acute, incurved at the apex. Stamens with free 
filaments and syngenesious anthers, which are produced at the base into long, slightly 
barbed tails. Achenes 23 lin. long, subterete, slightly grooved, glabrous. Pappus- 
bristles copious, 3-4 lin. long, nearly smooth or very slightly scabrid, pale tawny-white. 
Summit of Mount Roraima, 8600 ft., McConnell & Quelch, 652. 
This plant appears to. be nearly allied to the genus Moquinia, DC., but differs in habit 
and in its 1-flowered, densely-crowded heads. I am somewhat doubtful as to the 
exsertion of the floret from the involuere during flowering, as I have only seen the 
corollas in the bud state; when in fruit the achene is as long as the involuere and the 
pappus is entirely exserted.

VACCINIACEZ. 
PSAMMISIA CORIACEA, N. E. Brown, sp. n. Frutex glaber. Folia breviter petiolata, 
obovata, oblonga vel orbiculata, crasse coriacea, integra, infra reticulato-venosa. 
Flores in axillis aggregati, penduli. Pedicelli recurvi, bibracteolati. Calyx cum 
pedicello articulatus, limbo breviter 4-5-dentato. Corolla 4 poll. longa, tubulosa, 
ore angustata, breviter 4—5-loba, lobis erectis lineari-oblongis obtusis. Stamina 
inclusa, biseriata, libera, glabra, antheris longe bitubulosis. Ovarium subglobosum. 
Stylus corolla subzequilongus, nec exsertus. 
A shrub with a greyish-brown bark. Leaves shortly petiolate, thick and rigidly 
coriaceous, glabrous ; petiole 1-2 lin. long, stout ; blade 3-12 in. long, 1-12 in. broad,varying 
from obovate to orbieular, obtuse, entire, reticulately veined beneath. Flowers in clusters 
of 3-9 in the axils of the leaves, pedicellate, drooping.  Pedicels about 4 lin. long, 
curved, bibracteolate at the middie or below, glabrous. Bracteoles opposite or sub- 
opposite, 1-j lin. long, broadly ovate, obtuse or subapiculate, very minutely ciliate. 
Calyx about 27 lin. long, glabrous, jointed to the pedicel, truncate at the base, with a 
subglobose tube and a cup-shaped shortly 4-5-toothed limb, the teeth very much 
broader than long, acute or apiculate. Corolla 1 in. long, about 2 lin. diam., tubular, 
narrowed at the mouth, 4—5-lobed, glabrous inside and outside; lobes 1 lin. long, erect, 
linear-oblong, obtuse. Stamens 8-10, included, biseriate, glabrous; the shorter filaments 
1$ lin. long, the longer 12 lin. long ; anthers } in. long, with the cells passing into two
