X, c, 5 Merrill: Philippine Plants, XII 347 



A small, nearly glabrous herb, the stems prostrate and rooting 

 at the nodes, 4-angled, obscurely puberulent or glabrous, the 

 flower-bearing branches erect, slightly branched, less than 10 

 cm tall. Leaves in unequal pairs, the larger ones of each pair 

 ovate to broadly ovate, 1.5 to 2 cm long, about 1.5 cm wide, the 

 base broad, truncate or sometimes subcordate, rarely somewhat 

 decurrent, the apex acute or blunt, margins slightly undulate, 

 the smaller leaves of each pair similar but less than one-half as 

 large, both surfaces with small, scattered cystoliths; petioles 3 

 mm long or less. Spikes terminal and axillary, solitary, slender, 

 1 to 5 cm long, less than 0.5 cm in diameter, somewhat inter- 

 rupted, the bracts and bracteoles similar, broadly lanceolate, acu- 

 minate, 1-nerved, about 3 mm long, 0.8 mm wide, very slightly 

 hispid, not ciliate nor glandular. Calyx-segments all acuminate, 

 obscurely hispid with short hairs, not ciliate, 3 to 4 mm long, 

 one 1.2 mm wide, very obscurely 3-nerved, very obscurely retic- 

 ulate above, two narrowly lanceolate, 0.7 mm long, 1-nerved, the 

 fourth cleft to within 1.5 mm of the base, the lobes lanceolate, 

 1-nerved. Corolla 4 mm long, pale pink, glabrous, the tube not 

 constricted, the upper lip 1.5 mm long, 1.1 mm wide, rounded, 

 the lower one 3-cleft, the lobes elliptic-ovate, obtuse, nearly 1 mm 

 wide. Anthers 0.6 mm long, the cells parallel. 



Mindanao, District of Davao, Santa Cruz, Williams 2955, June 19, 1905. 



A species perhaps as closely allied to Lepidagathis tenuis C. B. Clarke 

 as to any other Philippine species, but quite distinct from that form. Well 

 characterized by its small size, small, unequal, broadly ovate, short-petioled 

 leaves and its slender, nearly glabrous spikes. 



RUELLIA Linnaeus 

 RUELLIA PANAYENSIS sp. nov. 



Species R. nudispicae C. B. CI. affinis, differt brevissime petio- 

 latis, inflorescentiis fasciculatis baud solitariis tenuioribus, 

 interdum ramosis. 



An erect herb about 20 cm in height, simple or sparingly 

 branched, the stems terete, 2.5 mm in diameter or less, ciliate- 

 hirsute, the younger parts rather densely so. Leaves oblong- 

 ovate, chartaceous, 4 to 9 cm long, 2 to 4 cm wide, somewhat 

 olivaceous, shining, apex rounded, base acute or subacute, the 

 upper surface glabrous, the lower more or less hirsute with 

 short hairs especially on the midrib and nerves, margins entire 

 or obscurely undulate ; lateral nerves about 8 on each side of the 

 midrib, slender; petioles pubescent, 3 to 5 mm long. Inflores- 

 cence mostly spikelike, apical, fascicled, 3 or 4 from each stem, 

 8 to 12 cm long, slender, glabrous or very slightly pubescent,
