TWO NEW SPECIES OF PLANTS FROM HAINAN 
By Elmer D. Merrill 
Director and Botanist, Bureau of Science, Manila 
From time to time in the past few years, botanical material 
from Hainan has been submitted to me by Miss Margaret M. 
Moninger, of the American Presbyterian Mission in Hainan, for 
identification. Much of the material has been collected in the 
vicinity of Kacheck and represents 1 for the most part species 
of wide distribution, although with a fair percentage of endemic 
species. The two forms described below are apparently new. 
GESNERIACEAE 
TRICHOSPORUM Jack 
TRICHOSPORUM MOMINGERIAE sp. nov. § Haplotrichium. 
Frutex glaber, ut videtur epiphyticus, usque ad 2 m altus; 
foliis oblongo-lanceolatis, in siccitate chartaceis, acuminatis, 
basi acutis, 7 ad 9 cm longis, usque ad 3 cm latis ; inflorescentiis 
cymosis, terminalibus vel axillaribus, tenuiter longe peduncu- 
latis, 5- ad 7-floris ; floribus circiter 3 cm longis, calycis 5-partiti, 
laciniis elliptico-ovatis, obtusis, circiter 4 mm longis. 
A glabrous, slender, apparently epiphytic shrub about 2 m 
high, the branches slender, terete, pale, the branchlets usually 
dark-olivaceous. Leaves apparently somewhat fleshy when fresh, 
when dry chartaceous, olivaceous, oblong-lanceolate, 7 to 9 cm 
long, 2.5 to 3 cm wide, subequally narrowed to the acuminate 
apex and to the acute base, the nerves slender, indistinct; 
petioles about 7 mm long. Cymes axillary and terminal, 5- to 
7-flowered, their peduncles slender, 8 to 10 cm long, the branches 
2 or 3, about 5 mm long. Bracts elliptic-ovate, about 5 mm 
long. Flowers orange-red, their pedicels 10 to 18 mm long. 
Calyx 5-parted, the lobes nearly free, elliptic-ovate, rounded, 
about 4 mm long. Corolla about 3 cm long, glabrous outside, 
very sparingly pubescent inside, somewhat curved, 5 to 8 mm 
wide when flattened, the mouth somewhat oblique, the lobes 
ovate, obtuse, about 8 mm long. Ovary glabrous, stipitate, 
including the short style about 2 cm long. Stamens exserted, 
the filaments slightly pubescent.
