VITEX Linn. 

 Vitex longifolia sp. nov. 



Arbor inflorescentiis exceptis glabra, circiter 13 m alta; foliis trifo- 

 liolatis, petiolo 5 ad 9 cm longo, foliolis oblongo-lanceolatis vel anguste 

 oblongo-ovatis, longe subcaiidato-aciiminatis, basi acutis vel acuminatis, 

 plus minus inaequilateralibus, usque ad 25 cm longis, subcoriaceis, nervls 

 utrinque circiter 10, subtus prominentibus ; paniculis termiiialibus, pedun- 

 culatis, amplis, plus minusve pubescentibus ; floribus fasciculatis. 



A tree about 18 m high, glabrous except the inflorescence. Branches 

 grayish, the ultimate ones somewhat compressed. Leaves 3-foliolate, the 

 petioles terete, 5 to 9 cm long. Leaflets oblong-lanceolate to broadly 

 ovate-lanceolate, subcoriaceous, somewhat shining when dry, brownish, 

 paler beneath, 20 to 25 cm 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 Avith 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
