fruit subglobose, red, 2.5 mm. in diameter, apiculate with the 

 base of the style. 



Woodlands, southeastern slopes of the John Crow Mountains, 

 350-600 m. altitude {Harris & Britton io,6q4, type; Britton 3937 ; 

 Harris & Britton 10,701); slopes, Cuna-Cuna Gap, Britton 4040) 



Plumiera jamaicensis sp. now 



An irregularly branched tree 8-10 m. high, the trunk up to 

 3 dm. in diameter. Leaves firm in texture, the blade elliptic, 

 12-15 cm - l n g> 5~7 cm - wide, rounded or emarginate at the apex, 

 narrowed at the base, glabrous on both sides, or minutely puber- 

 ulent on the veins beneath, the upper surface dark green with the 

 veins somewhat impressed, the under surface lighter green with 

 the broad nerves very prominent, diverging nearly at right angles 

 from the strong elevated midvein, the ultimate venation strongly 

 reticulated; petiole stout, 3-4.5 cm. long; peduncle stout, 18 cm. 

 long or less; flowers numerous; bracts broadly ovate, acutish, 

 1.5 mm. long; pedicels 8-13 mm. long; calyx nearly truncate, 

 with 5 short teeth; corolla white with a yellowish blotch at the 

 base of each lobe, the tube 1 cm. long, the lobes 2-2.5 cm - l n g> 

 oblong-obovate, obtuse; pods 15-22 cm. long, 1.5-2 cm. in

Coastal hillsides and thickets, parish of Portland. Wheeler- 

 field, March 13, 1909 {Britton 4123, type); near Port Antonio, 

 Sept. 25, 1906 {Britton 870). Near P. emarginata Griseb., of 

 Cuba. 



Valerianoides jamaicensis X mutabilis. 



Hybrids are not often seen in the West Indian flora, but the 

 one here recorded seems to be genuine. I found it growing near 

 its parents on a roadside between Mandeville and Brown's Town, 

 Manchester, with characters of foliage and flowers exactly inter- 

 mediate. 



Lantana jamaicensis sp. nov. 



A vine, climbing on trees, up to 7 meters long, or shrubby and 

 1 meter high, or less, the branches long, slender, terete, densely 

 puberulent. Leaves lanceolate to ovate, 2.5-9 cm - l n g> rather 

 firm in texture, acute or acuminate at the apex, narrowed or 

 rounded at the base, crenulate, sparingly pubescent above, densely 

 puberulent and rather prominently veined beneath, or becoming 

 glabrate, the petioles 1 cm. long or less; peduncles puberulent, 

 2-4 cm. long; heads involucrate, subgi bose in flower, 1 1 .5 cm.
