to the genus Sideroxylon, although the very small, or often aborted 

 staminodes, and the pubescent base of the ovary are characters that tend 

 toward the genus Chrysophyllum. 



SYMPLOCOCACE^E. 



Symplocos depauperata, sp. nov. 



A shrub about 3 m. high., with small, ovate, serrate leaves, and axillary 

 simple, racemose infloresence, 3 cm. long or less, and white flowers, the 

 ovary pubescent. Branches dark reddish brown, more or less pubescent, 

 becoming glabrous, the ultimate branchlets densely appressed ferruginous 

 pubescent. Leaves subcoriaceous, 1.5 to 4 cm. long, 1.8 cm. wide or less, 

 the base acute, the apex acuminate, margins finely serrate, or entire 

 near the base, the upper surface glabrous except for the pubescent midrib, 

 the lower surface with few scattered hairs, each hair from a small dark 

 colored papilla, the midrib rather densely pubescent; nerves obscure, not 

 more prominent than the reticulations; petioles densely pubescent, 2 to 3 

 mm. long. Racemes axillary, densely ferruginous pubescent, 10 to 15 

 flowered. Flowers white, 7 to 8 mm. in diameter, the bracts pubescent, 

 broadly ovate, acute, slightly exceeding 1 mm. in length, the pedicels 1 to 

 2 mm. long, pubescent. Calyx tube 1.5 mm. long, glabrous or with 

 very few scattered hairs, the lobes ovate, subobtuse, about 1.2 mm. long, 

 the margins minutely ciliate, the median portion more or less pubescent, 

 otherwise glabrous. Corolla lobes 4 mm. long, 2 to 2.5 mm. wide, elliptical- 

 ovate, obtuse. Stamens many, the filaments glabrous, the longer ones 

 4 mm. long, very slightly united at the base; anthers 0.8 mm. in diameter. 

 Ovary 3-celled, pubescent; style about 3 mm. long. Fruit glabrous, ovoid, 

 4 to 5 mm. long. 



Type specimens: No. 5909 (A. D. E. Elmer), Baguio, Province of 

 Benguet, Luzon, March 4, 1904 (flower) ; No. 6508 (Elmer), same locality, 

 June, 1904 (fruit); No. 10 (Topping), same locality, February, 1903 

 (immature fruit). 



A small shrub growing in the open plain region along streams, evidently 

 most closely related to Symplocos luzoniensis Rolfe, differing from that 

 species in its smaller leaves, longer, more numerously flowered spikes, 

 pubescent ovary, and nearly glabrous calyx. 



APOCINACE^E. 



Choneomorpha macrophylla G. Don. (Tabernaemontana elliptica Blanco, 

 Fl. Filip. ed. 1, 115; ed. 2, 83.; ed. 3, 1:152; F. Vill. Nov. App. 132.) 

 This species has recently been collected in the Philippines, Bosoboso, 

 Province of Rizal, Luzon, No. 1141 (Forestry Bureau), Ahern's collector, 

 June, 1904; also No. 2704 (Merrill), the same locality, June, 1903, its 

 previously definitely known range having been from the Himalayan region 

 to Ceylon, Malayan Peninsula, Andaman Islands, and Java. Blanco's 

 Tabernaemontana elliptica is certainly referable to this species, its identifica- 

 tion with this genus having been suggested by Fernandez- Villar.
