MEMOIRS OF THE NEW iORK BOTANICAL GARDEN 



Verbenaceae ' 

 Lippia venosa 



Densely and very shortly gray-tonieiitellate throughout, the 

 long slender branches somewhat quadrangular and sulcate. 

 Petioles 4 to 8 nun. long, the blades 3 to 5 cm, long, 1 to 2 cm. 

 broad, ovate with abruptly acuminate base and long-acuminate 

 and acute summit, shortly crenate-dentate, thickish, light-green 

 above, gray l)eneath, rather strongly bullate above by the im- 

 pressed venation, which is very prominent and stout beneath, 

 the strongly ascending secondaries about 5 on a side, connected 

 by a strong reticulation. Heads solitary in the axils, the slender 

 peduncles half as long as their leaves, or longer, mostly nearly 

 1 cm. broad. Bracts ciliate, broadly ovate, acute. Calyx broadly 

 campanulate, 2-fid, the divisions broader than long.' Corolla- 

 tube minutely puberulent, incurved, 5 mm. long, contracted just 

 above the l)ase, then gradually dilated to three times that width, 

 and lightly contracted at the summit, the Imib 5 mm. broad, the 

 upper lip very slightly retuse, the lower with 3 rounded lobes 

 which are rather broader than long. Shorter anthers reaching 

 to about the middle of the tube. 



Espia, at the head of the Bopi Elver, about 3,500 feet, H. H. 

 Ru.sbij, July 20, 1921 (no. 99) ; Canamina, 4,000 feet, 0. E. White, 

 July 21, 1921 {no. 26S). 



Petrea fragrantissima 



Scabrous throughout, the branches stout, terete, light-gray. 

 Petioles 1 to 1.5 cm. long, stout, the margins strongly involute. 

 Blades 12 to 18 cm. long, 7 to 12 cm. broad, with rounded base 

 and obtuse or acutish summit, entire, thickish, and rigid, deep- 

 green, the venation lightly prominent above, sharply and 

 strongly so beneath, the secondaries 12 to 15 on each side, 

 crooked, strongly anastomosing at some distance from the mar- 

 gin, and connected by a very loose angular anastomosis of the 

 tertiaries. Panicles pedunculate, loosely branched, elongated, 

 like their branches, loosely or densely flowered, recurved or pen- 

 dulous, the flowers of a deep-blue color and very fragrant. Bracts 

 equaling or exceeding the flowers, lance-linear, acuminate and 

 acute. Flowering pedicels 1.5 mm. long, in fruit 5 to 8 mm., very 

 slender. Tube of flowering calyx 5 mm. long, the narroAA^ cris- 

 pate lobes a little longer in fruit, the tube little longer, but the 

 lobes 2 cm. long by 1 cm. broad, obovate with rounded summit, 

 thin and veiny. Ligules of the cah'x thick, broader than long.
