Capparis collina, n. sp. (§ Cynophallophora.) Small tree: 

 leaves alternate, green, paler beneath, glabrous, dull, narrowly elliptical 

 or lanceolate, 6 to 9 cm. long, and 3 to 4.5 cm. wide, obtuse or rounded

 Valle, Johnston, no. 10, July 15, 1903. This species differs from C.

 a different shape ; in its smaller flowers and slender, smooth fruit.

 number, 5 to 7 mm. long, 1.5 mm. wide, everywhere pilose, paler on the 

 under side ; petiole 4 to 8 cm. long ; petiolules 3 to 5 cm. long : young 

 stem and petioles rufescent; stipules geminate, lanceolate, 6 mm. long:

 nate ; pinnae 4 to 6 in luimber ; pinnules 12 to 14 in number, nearly
