nerves and reticulations obsolete, or sometimes about 3 pairs 

 of lateral nerves evident but obscure, 2 to 4.5 cm 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, v^hen 

 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 (Kranzl.) [Aeschynanthus loheri Kranzl. in Philip. Journ. Sci, 

 8 (1913) Bot. 165], from which it differs in its much slenderer, entirely 

 glabrous flowers. Kranzlin 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:
