nerves and reticulations obsolete, or sometimes about 3 pairs 
of lateral nerves evident but obscure, 2 to 4.5 em long, 1.5 to 
3.8 cm wide, base rounded to obscurely cordate, apex obtuse to 
broadly and obscurely blunt-acuminate, the younger ones often 
slightly villous on the margins; petioles 2 to 4 mm long, when 
young more or less villous, when old quite glabrous. Flowers 
apparently dark red, on short, 1- or 2-flowered peduncles in the 
uppermost axils. Calyx cylindric, quite glabrous, about 2.5 cm 
long, very shallowly lobed, slightly enlarged upward. Corolla 
about 5.5 cm long, entirely glabrous, somewhat curved, contract- 
ed above the base, then expanded, the lobes broad, subequal; 
stamens slightly exserted; style pubescent in the lower one-half.

A species similar to and manifestly closely allied to TRICHOSPORUM 
LOHERI (Krinzl.) [Aeschynanthus loheri Kranzl. in Philip. Journ. Sci. 
8 (1913) Bot. 165], from which it differs in its much slenderer, entirely 
glabrous flowers. Krinzlin describes the flowers of Trichosporum loheri 
as glabrous, but both the calyx and corolla are distinctly but minutely 
pubescent externally.

The above is the first verification of F.-Villar’s record for this genus and 
species as a Philippine plant. Widely distributed in tropical Asia, Africa, 
and Malaya. 
POLYTREMA C. B. Clarke 
POLYTREMA ADDISONIENSE (Elmer) comb. nov. 
Hypoestes addisoniensis Elmer Leafl. Philip. Bot. 5 (1913) 1697. 
The type number of this is Elmer 12715, from Addison Peak, Palawan; 
the same species is apparently represented by Merrill 7235 from Ulugan 
Bay, Palawan, September, 1910. It is not a Hypoestes but is congeneric with 
the three species of the Malay Peninsula for which C. B, Clarke has pro- 
posed the generic name Polytrema. The Palawan species is apparently 
closely allied to Polytrema vulgare C. B. Clarke. The genus appears to 
be very closely allied to Hallieracantha Stapf. Here I also refer the 
following species:
