the smaller, exterior lip entire, the upper and inner lip strongly 3-lobed, and its 
calyx, which in anthesis is equally 5-toothed, but in fruit is accrescent and dis-

VITEX Linn. 
Vitex longifolia sp. nov. 
Arbor inflorescentiis exceptis glabra, circiter 12 m alta; foliis trifo- 
liolatis, petiolo 5 ad 9 cm longo, foliolis oblongo-lanceolatis vel anguste 
oblongo-ovatis, longe subcaudato-acuminatis, basi acutis vel acuminatis, 
plus minus inaequilateralibus, usque ad 25 cm longis, subcoriaceis, neryis 
utrinque circiter 10, subtus prominentibus ; paniculis terminalibus, pedun- 
culatis, amplis, plus minusve pubescentibus; floribus fasciculatis. 
A tree about 12 m high, glabrous except the inflorescence. Branches 
grayish, the ultimate ones somewhat compressed. Leaves 3-foliolate, the 
petioles terete, 5 to 9 em long. Leaflets oblong-lanceolate to broadly 
ovate-lanceolate, subcoriaceous, somewhat shining when dry, brownish, 
paler beneath, 20 to 25 em long, 5 to 7 cm wide, entire, the apex with 
a long, slender acumen, the base somewhat inequilateral, acute or acu- 
minate; nerves about 10 on each side of the midrib, beneath prominent, 
curved-ascending, rather distant, anastomosing, the primary reticulations 
lax; petiolules of the lateral leaflets less than 1 cm long, of the middle 
leaflet nearly 2 cm in length. Panicles terminal, solitary, equaling the 
leaves, the peduncle 15 cm long, sometimes with a single branch from 
the base, most of the primary branches from above the middle, usually 
about four at each node, the ultimate branches and branchlets more or 
less brown-pubescent. Flowers in fascicles on the ultimate branchlets, 
usually in groups of one central slightly pedicelled flower and two lateral 
shortly peduncled groups of three flowers each, the bracts small, 2 mm 
long or less. Calyx pubescent, cup-shaped, 2 mm long and wide, with 
five, short, acute teeth less than 0.5 mm long. Corolla lilac, pubescent 
inside and outside, the tube cylindric, 5 to 6 mm long, the upper lip 
bifid, 5 to 6 mm long, the lobes narrowly obovate, rounded, the lower lip 
3-cleft, the lobes oblong, acute or obtuse, 3 mm long. Filaments some- 
what pubescent, the longer two about 8 mm, the shorter ones about 6 mm 
‘in length. Fruit unknown.
