 present. Frnit obovoid, indeliiseeiit, woody, 4 io 5 cm long, strongly 

 rugose when dry, densely fulvous-hirsute or tomeutose, indeliiseent, 

 5-celled, each cell with a thick '3.5 cm long seed.

 190G, and additional material without numbers collected in .January, Febriiarv, 

 March, April, -June, and September, 1907. 



A striking genus, apparently allied to Chisocheton and Di/fioxi/lum, but very 

 distinct from both, and so far as I am able to determine, from all others in the 

 family, well characterized by its very large flowers, .5-celled ovary, 20 stamens 

 which are hirsute, 20-toothed staminal tube, and .5-celIed indeliiseent fruit. 



According to the collector, an erect, unbranched, or slightly branched tree, 4 

 to 6 m high, the trunk 5 to 10 cm in diameter, the leaves crowded at the apex 

 of the trunk, the inflorescence axillary, pendulous. 



CHISOCHETON Blume. 



Chisocheton dementis Merrill sp. nov. 



Arbor maxima, glabra, inflorescentiis exceptis ; foliis alternis, usque ad 

 60 cm longis, 2- ad 5-jugatis; foliolis subcoriaceis, pallidis, elliptico- 

 oblongis vel oblongis, 1.5 ad 30 cm longis, oppositis, breviter acnminatis, 

 nervis ntrinque ca. 10 ; panicnlis axillaribus, foliis subaeqnalibus, pube- 

 rulis, ramosis; floribus ca. 15 mm longis, extus dense adpresso-hirsutis. 



A tree reaching a height of 30 m. Branches thickened, reddish-brown, 

 glabrous. Leaves 60 cm long or less, 2- to 4-jugate, the rachis produced 

 and puberulent at the tip and with few undeveloped leaflets; leaflets op- 

 posite, elliptical-oblong or oblong, subcoriacepus, glabrous, pale, 15 to 30 

 cm long, 7 to 10 cm wide, sometimes slightly falcate, apex short-acuminate, 

 base acute or rounded, slightly inequilateral; nerves about 10 on each 

 side of the midrib, prominent beneath, the reticulations lax; petiolules 

 1 cm long or less. Panicles axillary, about as long as the leaves, the 

 lower brandies 15 cm long or less, puberulent, few-flowered. Calyx 

 cup-shaped, rugose, densely pubescent, about 4 mm long and wide, trun- 

 cate or obscurely toothed, the pedicels short and thick. Petals 5, linear- 

 lanceolate, thick, about 16 mm long, 2 mm wide, glabrous inside, densely 

 appressed-hirsute outside, recurved in anthesis. Staminal tube cylin- 

 drical, densely hirsute, about 12 mm long, 3 mm in diameter, cleft at 

 the apex into 6 oblong, truncate teeth, 3.5 mm long, 1.5 mm wide. Sta- 

 mens 6, alternating with the teeth of the staminal tube; anthers 3 mm 

 long. Disk none or very short. Style 12 mm long, hirsute, 5-sul('ate, 

 gradually narrowed upwards; stigma capitate, 1 nmi in diameter.

 ber, 1907. 



A species well characterized by its hirsute flowers and the curious prolonga- 

 tion of the leaf-rachis, with undeveloped leaflets. Resembling Chisocheton cuming- 

 iaiius (C. DC.) Harms, but the flowers verv dilTerent.
