pedicels stout red often unequal in same truss I-2 cm. long glab- 
rous but for an occasional peltate scale. Calyx small about 1.5 
mm. long, the cup glabrous the 5 short (about .5 mm. long) 
rounded lobes lepidote outside and with a few marginal cilia. 
Corolla lavender or purplish-rose with deep crimson markings 
posteriorly, butterfly-shaped about 3.5 cm. long elepidote epilose 
outside, puberulous inside ; tube short wide funnel-shaped from 
base expanding into a broad open 5-lobed limb hardly grooved 
inside or ridged outside ; lobes of the limb large nearly rotundate 
subequal as much as 2 cm. long and 2 cm. broad faintly emargi- 
nate. Stamens ro unequal longest about as long as corolla and 
gynaeceum with anther about 3 mm. long, shortest about 2 cm. 
long with anther about 2 mm. long; filaments dilated down- 
wards puberulous above the glabrous base to above mouth of 
corolla-tube. Disk nearly glabrous. Gynaeceum about as long 
as corolla and longest stamens ; ovary about 6 mm. long conoid 
truncate grooved densely lepidote ; style slightly puberulous

Szechwan rather than Yunnan is the home of the Triflorum 
series, and this species comes from the extreme S.W. region of 
Szechwan bordering on Yunnan. It is quite distinct from all 
of the Yunnan members of the series and from all of the described 
species from Szechwan, but recalls a plant which is in culti- 
vation sent out by Veitch under the name “ Rh. coombense.”’ 
There is no resemblance in this plant to the Rh. coombense, 
Hemsl., described and figured in the Botanical Magazine 
(1909), t. 8280. 
_ With Rh. oreotrephes, W. W. Sm., Rh. timeteum has alliance, 
but I see no trace of the wax-covering which is so distinctive 
a mark of Rh. oreotrephes as well as of Rh. triflorum, Hook. f., 
two species which are near relations within the Triflorum 
series, the latter a yellow-flowered Himalayan, the former a 
purple-flowered Chinese one. From Rh. oreotrephes the new 
species Rh. timetewm can be distinguished also by the scales of 
the underleaf indumentum which in Rh. oreotrephes are close-set
