doubts: the present, however, is a very natural group of species, 
including, besides P. flavum and P. serpens, the Vaccinium rugo- 
sum of Drs. Hooker and Thomson’s distributed Indian collec- 
tions, which is a native of the Sikkim Himalaya and Khasia 
mountains, and distinguished from P. favum by the lanceolate 
leaves, longer and more slender pedicels, broader foliaceous blunt 
calyx-lobes, and deep red corolla. The present species is erect 
when cultivated ; but, like many others of the Order, it probably 
prefers to grow epiphytically in shady forests. 
Descr. A shruéd, with glabrous, stout, woody branches. Leaves 
two to three inches long, ovate-lanceolate, acuminate, serrate, very 
shortly petioled, coriaceous, rugose above with reticulated veins, 
paler below. lowers in short axillary racemes, ‘pendulous or 
nodding. Peduacle short ; pedicels slender, red, minutely pubes- - 
cent. Flowers an inch long. Calyzx-tube short, hemispherical, 
five-winged ; limb five-lobed ; lobes triangular-ovate, acute, mar- 
gined with red. Corolla tubular, inflated, with five-angled and 
thick ribs, puberulous; lobes five, small, recurved. Stamens 
free ; filaments short, pubescent. Anther-cells oblong, produced 
into very long slender connate tubes, which are free at the apex, 
and open in front by long slits: two minute sywrs project back- 
wards from the tip of the anther-cells. Disc depressed, ten-lobed. 
Style erect, slender, slightly enlarged towards the apex, truncate ; 
stigma of five minute glandular points, placed within the truncated 
apex of the style. Fruit probably somewhat fleshy, as in P. rugo- 
sum, Hook. fil.
