PAVETTA ELMERl sp. nov. 
Frutex circiter 2 m altus, perspicue ciliato-pubescens ; foliis 
obovatis, membranaceis, usque ad 12 cm longis, obtusis ad obtuse 
acuminatis, basi acutis, nervis utrinque circiter 12, distinctis; 
inflorescentiis brevissime pedunculatis, confertis, multifloris, 3 
ad 4 cm longis, dense ciliato-villosis ; floribus 4-meris, corollae 
tubo 5 ad 6 mm longo. 
A shrub, about 2 m high, the leaves and inflorescences con- 
spicuously ciliate-pubescent. Branches terete, smooth, pale, 
shining, the very young growing parts densely ciliate with pale 
hairs. Leaves (immature) membranaceous, obovate, 9 to 12 
cm long, 5 to 7 cm wide, brown or black when dry, the apex 
obtuse to obtusely acuminate, the base acute, both surfaces prom- 
inently ciliate-pubescent especially on the midrib and lateral 
nerves ; lateral nerves about 12 on each side of the midrib, prom- 
inent; petioles densely pubescent, 1 cm long or less; stipules 
broadly ovate, acuminate, about 5 mm long, pubescent. Inflo- 
rescences densely many-flowered, 3 to 4 cm long, short-peduncled, 
the axis, branches, pedicels, and calyces densely and uniformly 
ciliate-pubescent with cinereous hairs. Calyx 2 to 2.5 mm long, 
the teeth 4, oblong, acute, nearly 1 mm long. Corolla-tube 5 to 
6 mm long, glabrous externally, inside somewhat pubescent, the 
lobes 4, oblong, about 4 mm long. Anthers 4 mm long. Ovary 
2-celled, cells 1-ovulate; style and stigma glabrous, at least 10 
mm long.

This species is well characterized by its rather dense and 
characteristic ciliate indumentum ; its obovate leaves ; its densely 
crowded, relatively short flowers; and its glabrous styles. It 
belongs in the group with Pavetta indica Linn., but does not 
appear to be very closely allied to that species. 
PAVETTA MULTINERVIA sp. nov. 
Frutex 3 ad 5 m altus, inflorescentiis parcissime puberulis 
exceptis glaber; ramulis compre'ssis vel angulatis; foliis lanceo- 
latis ad oblongo-lanceolatis, membranaceis vel chartaceis, usque 
ad 25 cm longis, in siccitate nigris, nitidis, utrinque acuminatis, 
nervis utrinque circiter 15, perspicuis; inflorescentiis peduncu- 
latis, trifidis 11 ad 13 cm lungis; floribus 5-meris, calycis tubo 
6 mm longo, lobis oblongo-oblanceolatis, circiter 12 mm longis. 
A shrub, 3 to 5 m high, entirely glabrous except the sparingly 
puberulent inflorescence. Branchlets brown or black when dry,
