forms of the species above described, and is certainly cogeneric, if not cospecific 

 with it; the specimen is, however, young, and additional material may show more 

 marked points of differentiation. 



Vernonia acrophila sp. nov. § Strobocalyx. 



Arbor parva, circiter 5 m alta, subglabra; foliis coriaceis, oblongo- 

 ovatiSj acuminatis, circiter 3.5 cm longis; corymbis terminalibus, plus 

 minus congestis, capitulis 3- vel 4-floris, squamis imbricatis, plus minus 

 puberulis, margine obscure ciliatis; achenio 2 mm longo, glanduloso. 



A small tree about 5 m high, the trunk 15 cm in diameter, subglabrous. 

 Branches short, stiff, the ultimate ones more or less crowded, black or 

 grayish, lenticellate, glabrous or nearly so. Leaves oblong-ovate, coria- 

 ceous, about 3.5 cm long, 1.2 to 1.5 cm wide, the apex shortly acuminate, 

 acumen blunt, base acute or acuminate, the margins somewhat reflexed, 

 glabrous, dark-colored when dry ; nerves 5 or 6 on each side of the midrib, 

 distant, anastomosing, distinct beneath ; petioles slender, 4 to 6 mm long. 

 Inflorescence terminal, somewhat congested, subglabrous. Involucral 

 bracts several-seriate, the outer ones ovate, obtuse, 1 mm long or less, the 

 inner ones gradually longer, the innermost oblong, 2.5 to 3 mm long and 

 deciduous, all slightly puberulent or nearly glabrous, the margins ob- 

 scurely ciliate. Achenes 3 or 4 in each involucre, 2 mm long, irregularly 

 and obscurely angled, and with numerous, scattered, waxy glands ; pappus- 

 hairs stiff, scabrid, about 24, 4 mm long, with a number of shorter sup- 

 plementary ones intei'mixed, these 1 mm long or less. 



Luzon, Province of Zambales, Mount Tapulao, For. Bur. 8057 Curran & 

 Merritt, October 13, 1907, in the elfinwood, exposed peaks, above an altitude of 

 2,000 m. 



As Vernonia arborea Ham. is interpreted by Hooker f., perhaps the present 

 form would be included, possibly as a variety or as a reduced form. It differs so 

 strongly in its very much reduced leaves and in being nearly glabrous throughout, 

 that it has been considered to be worthy of specific rank. 



Vernonia lancifolia sp. nov. § Strobocalyx. 



Vernonia arborea Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 138, non Ham. 



Arbor subglabra 4 ad 5 m alta; foliis lanceolatis, valde acuminatis, 

 usque ad 12 cm longis, 2.5 cm latis, coriaceis vel subcoriaceis, glabris, 

 subtus glandulosis, nervis utrinque 9 ad 12, distinctis; squamis puber- 

 ulis; achenio 2 ad 2.4 mm longo. 



A tree 4 to 5 m high, nearly glabrous throughout. Branches grayish 

 to nearly black, terete, glabrous, the ultimate branchlets sometimes pubes- 

 cent. Leaves coriaceous, lanceolate, 5 to 12 cm long, 1.5 to 2.5 cm wide, 

 glabrous, somewhat shining above when dry, the apex sharply subcaudate- 

 acuminate, the base acute or acuminate, the lower surface with numerous, 

 minute, yellow, shining, waxy glands ; nerves 9 to 12 on each side of the 

 midrib, beneath distinct, anastomosing, the reticulations rather lax ; peti- 

 oles slender, 3 to 10 mm long. Inflorescence terminal, 6 to 12 cm in 

 diameter, glabrous or nearly so, or the branchlets somewhat pubescent.
