showy, odorless; pedicels thick, terete, ascending, reddish; 
corolla heavy and somewhat fleshy, 2 to 3 inches long, purple 
red, the rotate lobes as widely spreading as the flower is long;

Rhododendron apoanum Stein 
Field-note for 11386:—4An erect shrub, 3 feet high; stem 
usually several, numerously branched above the middle; the 
suberect twigs grayish brown; leaves numerous, ascending, 
grayish brown beneath or the young ones scurfy brown on both 
sides; flowers terminal or upon short special stalks, quite 
numerous and forming dense blood red cluster; corolla broadly 
cylindric, 0.75 inch long, upon glandularly scurfy pedicels. 
This the Bagobos eal ‘‘Calumping-busau.’’ 
Represented by numbers 11386 and 10630, Elmer, Todaya 
(Mt. Apo), Mindanao, August and May, 1909. 
The former number is typical R. apoanum Stein. The lat- 
ter number was collected on a wooded ridge at 7500 feet of 
mount Calelan, and had a subscandent epiphytic habit. Stein’s 
species came from the chaparral region of Apo, since none of 
the former botanists have explored mount Calelan. Number 
10630 is somewhat similar to R. nortonae Merr. which the 
writer also collected in southern Negros.
