11 mm longis, cinereo-pubescentibus ; floribus circiter 18 mm 

 longis. 



An erect, suffrutescent, branched plant, up to 50 cm high, 

 more or less cinereous-pubescent. Leaves in equal or distinctly- 

 unequal pairs, ovate to oblong-ovate, acutely acuminate, base 

 acute, membranaceous, olivaceous, the larger ones 6 to 12 cm 

 long and 4 to 6 cm wide, the smaller ones 3 to 6 cm long and 

 2 to 3 cm wide, the upper surface rather minutely cinereous- 

 pubescent with scattered hairs, the indumentum more conspic- 

 uous on the midrib, the lower surface somewhat pubescent, 

 paler; lateral nerves 6 or 7 on each side of the midrib, slender, 

 distinct; petioles cinereous-pubescent, 1 to 4 cm long. Flowers 

 pink, chiefly axillary, the involucres few, solitary or fascicled, 

 never more than 5 in a fascicle, sessile or shortly peduncled; 

 bracts 4, lanceolate, slenderly acuminate, about 11 mm long, 

 sparingly cinereous-pubescent, the outer two united for the 

 lower 3 m.m. Calyx 5 to 6 mm long, pubescent, membranaceous, 

 the lobes lanceolate, acuminate, 2 mm in length. Corolla 1.8 

 cm long, sparingly hirsute externally in the upper two-thirds, 

 the tube 9 mm long, glabrous below, the lower lip 9 mm long, 

 3-lobed, the lobes broadly ovate, rounded, 2 mm in length. Fila- 

 ments 7 mm long, slightly ciliate; anthers 1.5 mm long.

Among the Philippine species perhaps as close to Hypoestes 

 subcapitata C. B. Clarke as any, but remote from it in its vegeta- 

 tive, inflorescence, and bract characters, the bracts l)eing merely 

 pubescent, not at all ciliate. A striking character of the present 

 species is its chiefly axillary inflorescences, the involucres being 

 fascicled, not arranged on an elongated rachis, and often solitary 

 or in pairs, or never exceeding five in a single inflorescence. 



HYPOESTES TENUIS sp. nov. 



Herba parva, ramosa, circiter 20 cm alta, erecta vel deorsum 

 decumbens, caulis vix 1 mm diametro; foliis in paribus aequali- 

 bus, ovatis ad oblongo-ovatis, membranaceis, 1 ad 3 cm longis, 

 obtusis vel obtuse acuminatis, nervis utrinque 3 vel 4 ; inflores- 

 centiis axillaribus terminalibusque, involucris paucis, plerumque 

 spicatim dispositis, spicis usque ad 5 cm longis; bracteis 4, 

 lanceolatis, acuminatis, 8 ad 9 mm, longis, minute cinereo-pubes- 

 centibus; floribus 1.5 cm longis.
