few-flowered, the bracts green, sessile, reniform-ovate, acumi- 
nate, 3 to 4 mm long, the pedicels about 3 mm long. Flowers 
5-merous, pink. Calyx cup-shaped, 4 to 5 mm long, densely 
covered with spreading purplish hairs 3 to 4 mm in length, 
the lobes linear-lanceolate, 3 mm long, setose-penicillate. Petals 
(from nearly mature buds) orbicular-ovate, 4 to 5 mm long, 
margins ciliate, apex penicillate. Stamens 10, equal; anthers 
oblong, 2 mm long. Fruit globose, about 5 mm in diameter. 
Mindanao, Zamboanga District, Sax River Mountains back of San Ra- 
mon, Merrill 8082, November 28, 1911, in damp shaded ravines on talus 
slopes, and on ridges, altitude 800 to 1100 m, rare. 
A species well characterized by its small flowers, in this readily dis- 
tinguishable from the other species of the genus. 
OTANTHERA M ACGREGORI I sp. nov. 
Frutex 1.5 ad 2 m altus, erectus, ramis ramulisque gracilis, 
teretibus vel obscure tetragonis; foliis oblongis vel oblongo- 
ovatis, acuminatis, basi 5-nerviis, supra adpresse strigosis, sub- 
tus ad nervis nervulisque setoso-strigosis ; floribus 5-meris calycis 
setis simplicibus, curvato-adpressis, strigosis, lobis lanceolatis, 
5 mm longis; petalis roseis, 6 mm longis. 
An erect shrub, 1.5 to 2 m high, the branches and branchlets 
terete or obscurely 4-angled, very slender, uniformly and rather 
densely appressed-strigose, brownish when dry. Leaves oblong 
to oblong-ovate, chartaceous, 5 to 8 cm long, 1.5 to 2.5 cm wide, 
the apex acuminate, base acute, 5-nerved, the upper surface 
uniformly appressed-strigose, the setae 1 to 2 mm long, the lower 
surface setose-strigose with somewhat curved setae on the nerves 
and reticulations; petioles about 5 mm long, strigose. Panicles 
terminal and axillary, few-flowered, usually about 2 cm long, 
sessile or peduncled, the bracts narrowly ovate, acuminate, setose, 
about 3 mm long. Flowers 5-merous. Calyx-tube globose, 
about 5 mm in diameter, covered with curved-appressed simple 
setae about 1 mm in length, the lobes lanceolate, acuminate, as 
long as the tube, ciliate-setose. Petals pink, broadly obovate, 
6 mm long, 7-nerved, reticulate, equilateral, the apex broad, sub- 
truncate, the margins slightly ciliate-setose. Stamens 10, equal ; 
filaments about 2.5 mm long; anthers as long as the filaments, 
narrowly oblong, obtuse, the connective not at all produced, the 
anterior basal appendages two, very short. Style 5 mm long, 
Luzon, Nueva Vizcaya Province, Imugan, Bur. Sci. 14-^08 McGregor, 
April 26, 1912. 
This species is manifestly allied to Otanthera celebica Blume, differing 
however in many characters, but especially in its calyx-lobes being more 
than twice as long as in Blume’s species and equaling the tube in length.
