I, 139, fc. 28). Gaertner however, defines and figures Tarenna astetramerous. We 

 therefore for these pentamerous species revive the genus Stylocoryna (established in 

 1797 by Cavanilles ; Cav. Ic. IV. 46, t. 368) which that author describes as pentame- 

 rous and inany-seeded. For the genus Wehera of Schreber we reserve in the present 

 work certain tetramerous uni-ovulate plants which in external characters resemble 

 Ixora and Pavetta. In Engler's Pflanzen.familien Welera, Schreb., is reduced to 

 Chomelia, a genus founded by Linnajus in 1737. This name Wehera was subsequently 

 adopted by two botanists, Jacquin and Vellosa, for two distinct geuera. There ia 

 thus much confusion connected with it.

1. Stylocoryna angustifolia, King n. sp. A shrub 4 to 6 feet 

 high, glabrous except the inflorescence; young brandies striate, thinner 

 than a goose-quill. Leaves coriaceous, narrowly oblong-oblanceolate, 

 much but rather bluntly acuminate, gradually narrowed from the middle 

 to the petiole, the edges (when dry) much recurved; both surfaces 

 blackish when dry, shining, the midrib deeply depressed on the upper 

 bold and promineut on the lower surface; main-nerves 5 or 6 pairs, 

 oblique, ascending, indistinct on both surfaces; length 2*5 to 3 5 in.* 

 breadth 75 to 1 in. ; petiole '2 to '35 in. Stipules broad, transversely 

 oblong, abruptly acuminate, •25 in. long. Cymes less than lin. in diain , 

 solitary, terminal, shortly pedunculate, not (even including the peduncles) 

 half so long as the leaves, the branches few, ascending, compressed, 

 puberulous witli lanceolate spreading bracteoles; 3- to 5-flowered.
