in outline. Fruits oblong-ovoid, about 1 cm long, densely ferru- 

 ginous-pilose. 



Luzon, Benguet Province, Mount Tonglon, For. Bur. 920 

 Barnes (type), May, 1904, Merrill 7801, May, 1911. In very 

 damp shaded ravines in the mossy forest, altitude about 2,000 

 meters. A form of the sam.e species is represented by Bur. 

 Sci. STS^'l, 37800 Ramos & Edano from Bontoc and Kalinga 

 Subprovinces, Luzon, February and March, 1920, these speci- 

 mens differing from the type in being more densely pilose and 

 in some of the larger leaves being obtuse or even obliquely 

 cordate at the base. 



This species has been confused with Cyrtandra lobbii C. B. 

 Clarke, from which it differs radically in its very dissimilar 

 leaves, the smaller one of the pair being sessile, ovate, deeply 

 cordate and entirely different in shape and size from the larger 

 one of each pair. 



CYRTANDRA ZAM BOANGENSIS sp. nov. § Dissimiles. 



Species C. auriculatae affinis, differt foliis omnibus petiolatis, 

 crenatis, baud lobatis, paribus leviter inaequalibus, floribus 

 multo minoribus, ovarium glabrum. 



A slender, prostrate, conspicuously ciliate herb, the main stems 

 up to 30 cm in length, rooting at their nodes, and with short 

 ascending branches, the stems, branches, and branchlets densely 

 ciliate with rather weak, jointed hairs. Leaves opposite, those 

 of each pair unequal, all petioled, the larger one of each pair 

 usually about twice as large as the smaller one but similar in 

 shape, the larger ones elliptic, up to 4 cm long and 2.2 cm wide, 

 the smaller ones, up to 2 cm long and 1.5 cm wide, all mem- 

 branaceous to chartaceous, olivaceous, obtuse or rounded, acute 

 to rounded at the base, somewhat crenate, both surfaces 

 supplied with numerous, long, weak, jointed hairs, these hairs 3 

 to 5 mm in length, pale ; lateral nerves 4 or 5 on each side of the 

 midrib, not prominent; petioles densely villous, 5 to 15 mm long. 

 Flowers white, about 14 mm long, terminal or in the upper axils, 

 the peduncles 1 to 2 mm long, pilose, 2-flowered, 2-bracteate, the 

 bracts oblong, 3 mm long, somewhat pilose, the pedicels 1 to 1.5 

 mm in length. Calyx 6 mm long, pilose, the lobes 5, lanceolate, 

 caudate-acuminate, as long as the tube. Corolla tube sparingly 

 pilose in the lower half, the tube slender in the lower 5 to 6 mm, 

 then widened, the lobes ovate, 3 to 3.5 mm long. Filaments 

 2.5 mm long, glabrous, the anthers 1 mm in length. Disk cup- 

 shaped, glabrous, 1 mm high, crenulate. Ovary oblong-ovoid.
