APOCYNACE^. 



Alstonia parvifolia sp. nov. 



A shrub or small tree 3 to G m. high, with whorled, lanceolate, acuminate, 

 distantly nerved leaves, the ultimate branches of the inflorescence and cal- 

 yces densely mealy pubescent the corollas glabrous or nearly so. Branches 

 dark gray, glabrous, the ultimate branchlets reddish brown. Leaves 6 to 

 13 cm. long, 1 to 3.5 cm. wide, subcoriaceous, tapering above to the usually 

 slender, blunt acumen and below to the narrow, somewhat decurrent 

 base, the margins revolute; nerves about 18 pairs, subprominent; petioles 

 1 to 2 cm. long. Cymes subumbellate in the upper axils, 7 cm. long or less, 

 the peduncles glabrous, the ultimate branchlets, bracteoles, and calyces 

 denselj' mealy pubescent. Flowers white, fragrant. Caly.K cjimpanulate, 4 

 mm. long the lobes short, obtuse. Corolla 8 mm. long, glabrous outside, 

 the tube about 4 mm. long, slightly contracted at the mouth and sparingly 

 villous inside. Stamens about 1 mm. long. Ovarj' ovoid, glabrous, 

 2-celled, many ovuled; style 2 mm. long. Follicles in pairs glabrous, 20 cm. 

 long, about 3 mm. in diameter. Seeds oblong, 6 mm. long, pubescent with 

 brownish hairs, the aj^ices and margins above long pilose. 



Type specimen: Mount Mariveles, Province of Bataan, Luzon (2209 

 Meyer), November, 1904 (flower). From the same locality: (G87G Elmer), 

 November, 1904 (flower); (1164 \Yhitford), March, 1905 (fruit). 



A species apparently closely related to Alstonia macroplii/lla Wall., dif- 

 fering from the latter in its much smaller, firmer, glabrous leaves, more 

 congested inflorescence and very densely mealy-pubescent calyces and 

 younger parts of the inflorescence. A small tree growing on exposed ridges 

 in the mossy forest at an altitude of about 1,100 m. above the sea. 



Eliertonia mcgregori sp. nov. 



A scandent, nearly glabrous shrub with opposite, ovate, acuminate, mem- 

 branous, opposite leaves and many flowered cymose axillary panicles, the 

 flowers, including the corolla lobes, about 1.5 cm. long. Branches twining, 

 glabrous, brown. Leaves 8 to 20 cm. long, 5 to 10 cm. wide, the base 

 broad, rounded or cordate, glabrous, except for few scattered hairs on the 

 nerves and margins of the younger leaves; nerves prominent, 9 to 12 on 

 each side of the midrib, spreading, strongly anastomosing the primary retic- 

 ulations subparallel, the nerves and reticulations darker colored and in 

 strong contrast to the surface of the leaves ; petioles 1 to 2.5 cm. long, 

 somewhat strigose pubescent, becoming glabrous. Inflorescence axillary, 15 

 to 18 cm. long, somewhat strigose ferruginous pubescent, especially the 

 branchlets, many flowered. Flowers fragrant, the pedicels 3 to 4 mm. long, 

 the bracteoles broadly triangular ovate, about 1 mm. long. Calyx eglan- 

 dular, the lobes elliptical ovate, obtuse, about 1 mm. long, the margins 

 somewhat ciliate. Corolla salver shaped, white, the lower part of the tube
