16,6 Merrill: Philippine Euphorbiaceae, III 545 



Mindanao, Bukidnon Subprovince, near Tanculan, Bur. Sci. 

 26112 Fenix, July 17, 1916, in open grasslands. 



This species is apparently dwarfed due to its habitat. Like 

 several forms in other genera which occur in open cogon areas, 

 the root becomes more or less thickened and produces few to 

 many shoots which endure but one or two years, as all but the 

 subterranean parts of the individual plants are destroyed by the 

 annual grass fires. In habit it is quite different from any other 

 species known to me. 



GLOCHIDION CAULIFLORUM sp. nov. § Euglochidion. 



Arbor parva; foliis subcoriaceis, oblongis ad oblongo-ovatis, 

 usque ad 25 cm longis, plus minusve pubescens vel vetustioribus 

 subglabris, breviter acuminatis, basi latissime et abrupte sub- 

 truncato-rotundatis admodum leviter cordatis, nervis utrinque 9 

 ad 11, perspicuis; inflorescentiis caulinis, racemosis, racemis soli- 

 tariis vel fasciculatis, 3 ad 12 cm longis, floribus fasciculatis, 

 floribus $ campanulatis, circiter 4 mm longis, segmentis par- 

 cissime ciliatis, staminibus 5; fructibus obovoideis, 10- ad 12- 

 locellatis, circiter 3 cm longis, leviter pubescens, valvis sublig- 

 nosis. 



A small tree 5 to 6 m high, the younger branches densely 

 pubescent. Leaves subcoriaceous, oblong to oblong-ovate, 13 

 to 25 cm long, 5 to 9 cm wide, the apex shortly acuminate, the 

 base broadly and abruptly rounded, sometimes shallowly cor- 

 date, brownish or olivaceous when dry, more or less pubescent 

 on both surfaces or in age the upper surface nearly glabrous; 

 lateral nerves 9 to 11 on each side of the midrib, prominent, the 

 reticulations very distinct on the lower surface; petioles stout, 

 up to 4 mm in length. Inflorescence from the trunk and per- 

 haps from the larger branches, solitary or two or three from a 

 tubercle, racemose, 3 to 12 cm long, pubescent, the male and 

 female flowers borne on the same raceme, fascicled at the leaf- 

 less nodes of the racemes. Pedicels of the male flowers 5 to 

 6 mm long, glabrous or very slightly ciliate, the perianth cam- 

 panulate, about 4 mm long, the lobes elliptic or elliptic-ovate, 

 obtuse, sparingly ciliate with few, long, scattered, spreading 

 hairs. Stamens 5, the staminal mass ellipsoid including the some 

 what produced connectives, about 1.7 mm long. Female flowers 

 apparently few, sometimes in separate inflorescences, sometimes 

 in the same fascicles with the male flowers. Sepals oblong- 

 lanceolate, pubescent, about 3.5 mm long and somewhat accres- 

 cent. Fruit obovoid, 10- to 12-celled, about 3 cm long, white
