Suffruticosa, subscandens, stipulis inflorescentiisque plus 

 minusve hirsutis exceptis glabra; caulis teretibus, laevis, 4 mm 

 diametro, ramulis plus minusve compressis vel sulcatis; foliis 

 chartaceis ad subcoriaceis, lanceolatis, usque ad 10 cm longis 

 et 3 cm latis, breviter petiolatis, acutis vel obscure acuminatis, 

 basi acutis, nervis utrinque 5, adscendentibus, perspicuis, re- 

 ticulis obsoletis; stipulis latis, pectinatis, laciniae circiter 7, 

 hirsutae, longioribus 6 ad 9 mm longae; inflorescentiis axillari- 

 bus, cymis laxis, 1 cm longis, paucifloris, leviter hirsutis, calycis 

 lobis oblongo-lanceolatis, acuminatis, 1.5 ad 2 mm longis. 



A suffrutescent, scandent plant at least 1 m high, glabrous 

 except the stipules and inflorescences. Stems terete, smooth, 

 dark-colored, about 4 mm in diameter, the younger branchlets 

 usually compressed or sulcate. Leaves chartaceous to subco- 

 riaceous, lanceolate, 7 to 10 cm long, 2 to 3 cm wide, greenish 

 olivaceous, smooth, glabrous, slightly shining, the lower surface 

 paler than the upper, the apex acute or slightly acuminate, the 

 base acute ; lateral nerves 5 on each side of the midrib, ascending, 

 scarcely anastomosing, prominent, the reticulations obsolete; 

 petioles stout, 3 to 4 mm long; stipules broad, the body about 

 3 mm long, 6 to 9 mm wide, glabrous, subtruncate, pectinate, 

 the lobes about 7, linear, stiff, more or less hirsute, the inner 

 ones 6 to 9 mm long, the outer ones gradually shorter, a few 

 intermediate ones often present, 1 mm or less in length. Cymes 

 axillary, lax, few-flowered, about 1 cm long, sparingly hirsute, 

 the pedicels 2 to 3 mm long, slender. Calyx tube about 1 mm 

 long, glabrous or nearly so, the lobes 4, oblong-lanceolate, some- 

 what acuminate, slightly hirsute, 1.5 to 2 mm long. Capsules 

 globose, 1.5 mm in diameter, crowned by the persistent calyx 

 lobes.

 thickets at low altitudes. 



The specimens were originally identified as Hedyotis rigida 

 Miq., but represent a species rather remote from the one de- 

 scribed by Miquel. It is strongly characterized by its short 

 petioles, glabrous, lanceolate, acute, prominently and obliquely 

 nerved leaves, the reticulations being obsolete, as well as by 

 its stipule and inflorescence characters.
