midrib, rather prominent, anastomosing, the primary reticula- 

 tions lax, distinct; petioles pubescent, 8 to 10 mm long. In- 

 florescences terminal and in the leaf axils on the ultimate 

 branchlets, the individual ones short, 2 to 4 cm in length, each 

 composed of from 2 or 3 to 5 racemosely arranged heads, the 

 peduncles pubescent, up to 1 cm in length. Heads about 14 

 mm long, approximately 8-flowered, subcylindric, the outer 

 bracts ovate, 2 mm long, distinctly pubescent, the inner ones 

 gradually longer, the innermost about 7 mm long, 3 mm wide, 

 acute, their margins and tips more or less pubescent; achenes 

 4 mm long, with numerous, shining, yellowish glands, the pappus 

 copious, about 6 mm long, straw-colored or pale brownish.

A species most closely allied to Vernonip, lenticellata Elm., 

 but with somewhat larger leaves and larger heads, the peduncles 

 also longer in the present species. It differs further in the 

 cystolith-like ultimate reticulations; its very sparingly lenticel- 

 late branches; and in the involucral bracts being pubescent 

 chiefly on the margins and at their apices. 



VERNONIA MINDANAENSIS sp. nov. 



Frutex scandens, partibus junioribus sordide pubescentibus j 

 foliis chartaceis ad subcoriaceis, oblongis ad oblongo-obovatis, 

 integris, 6 ad 8 cm longis, acuminatis, basi acutis, subtus eglan- 

 dulosis, pubescentibus, nervis utrinque circiter 5; inflorescentiis 

 paniculatis, usque ad 18 cm longis; capitulis, numerosis, 1.5 ad 

 1.7 cm longis, circiter 20-floris ; bracteis dense cinereo-pubescen- 

 tibus, interioribus 10 mm longis; acheniis glabris, sulcatis, 4 mm 

 longis. Species V. philippinensis affinis differt acheniis gla- 

 berrimis. 



A woody vine reaching a height of 10 m, the branches dark 

 reddish brown, striate, terete, somewhat pubescent, the ultimate 

 branchlets 2 to 3 mm in diameter, rather densely pubescent with 

 short, dirty brown hairs. Leaves chartaceous to subcoriaceous, 

 oblong to oblong-obovate, entire, 6 to 8 cm long, 2.5 to 8.5 cm 

 wide, the apex shortly acuminate, base cuneate, the upper sur- 

 face dark olivaceous, shining, nearly glabrous except for the 

 sparingly pubescent midrib and nerves, the lower surface paler, 

 eglandular, with scattered pubescence on all parts but more espe- 

 cially on the midribs, nerves, and reticulations; lateral nerves 

 about 5 on each side of the midrib, curved-anastomosing, distinct,
