glabrous on the back. Corolla tubular-campanulate crimson 
about 3.8 cm. long; tube glabrous outside and inside 5-gibbous 
retuse fleshy at the base with 5 imperfect interpetaline septa ; 
lobes 5 rounded about 8 mm. long and 2 cm. broad eMarginate 
and crenulate. Stamens 10 subequal much shorter than corolla, 
longest about 2 cm. long, shortest about 1.8 cm. long ; fila- 
ments dark-crimson at slightly-widened base, glabrous ; anthers 
rich brown about 2 mm. long. Disk large 1 cm. long puberu- 
lous below ovary. Gynaeceum about 2.1 cm. long equalling 
or slightly longer than stamens; ovary about 4 mm. long 
grooved cylindric-conoid truncate densely tomentose with 
complete cover of floccose greasy pinkish adpressed ascending 
hairs those at top forming a crest around base of style ; style 
glabrous hardly swollen at top beneath the lobulate stigma. 
Capsule as much as 2.5 cm. long and 5 mm. broad (sometimes 
much smaller) brown faintly bristly or warted slightly oblique 
to pedicel nearly straight, calyx-cup conspicuous and enlarged 
at its base, dehiscing from apex by five valves which leave a 
stylopodar fringe. Seeds small 1.75 mm. long .75 mm. broad 
without arillar wing or crest, pale brown, testa striate, chalazal 
end rounded, funicular end truncate minutely fringed.

Rh. repens as displayed in the specimens cited is a plant of 
the same habit as and in other characters very like RA. Forrestii, 
Balf. f. The species are very nearly allied. The general 
appearance of the plants in dried specimens suggests specific 
difference and confirms the conclusion at which Forrest has 
arrived from his observation of the plants growing in their 
habitats. Yet critical consideration of the details of structure 
shown by the dried specimens raises the question—Have we 
here one or two species ? And this I propose to discuss.
