This species is readily distinguished by its narrowly lanceo- 

 late, very sharply acuminate and cartilaginous-mucronate leaves 

 as well as by its terminal, fascicled fruits, these being obovoid 

 and much narrowed below the middle to form a very distinct 

 pseudostalk. 



PITTOSPORUM ACUMINATISSIMUM sp. nov. 



Frutex epiphyticus vel pseudo-epiphyticus, glaber, ramulis te- 

 nuibus; foliis chartaceis, oblongis ad oblongo-ellipticis, nitidis, 

 tenuiter acute acuminatis, usque ad 8 cm longis, nervis utrinque 

 7 ad 9, tenuibus ; inflorescentiis solitariis, lateralibus et termina- 

 libus, brevibus, 3-floris; floribus circiter 12 mm longis, ovario 

 dense villoso; fructibus leviter compressis, 2-valvis, ellipsoideis, 

 circiter 23 cm longis, valvis crasse carnoso-coriaceis, in siccitate 

 rugosis. 



An epiphytic or pseudoepiphytic shrub, entirely glabrous ex- 

 cept the densely pubescent ovaries, the ultimate branches slender, 

 2 to 3 mm in diameter. Leaves chartaceous, oblong to oblong- 

 elliptic, brownish-olivaceous when dry, 5 to 8 cm long, 2 to 4 

 cm wide, the apex sharply and slenderly acuminate, base acute ; 

 lateral nerves 7 to 9 on each side of the midrib, slender as are 

 the reticulations ; petioles 2 to 3 cm long, slender. Inflorescences 

 usually solitary, lateral, rarely terminal, usually 3-flowered, their 

 peduncles 5 mm long or less, the pedicels 5 to 10 mm long. Calyx 

 shallowly cup-shaped, about 4 mm in diameter, the lobes broadly 

 ovate, obtuse, 1.5 to 1.8 mm long. Petals 5, narrowly oblong, 

 11 mm long, 3.5 mm wide, obtuse. Filaments 4 to 4.5 mm long. 

 Ovary oblong-ovoid, densely villous; style glabrous, 1.5 mm long. 

 Capsules ellipsoid, somewhat compressed, 2-valved, about 2.3 cm 

 long, 1.8 cm wide, the valves thick, fleshy-coriaceous, rugose 

 when dry.

This form has the same habit as Pittospoi-um resiniferum 

 Hemsl. and is manifestly closely allied to that species. It diff'ers 

 in its smaller leaves and its usually solitary, lax, few-flowered 

 inflorescences; in Hemsley's species the flowers are borne in 

 dense fascicles, while in the present species they are in depau- 

 perate, 3-flowered, usually solitary cymes. 



PITTOSPORUM GLABERRIMUM sp. nov. 



Frutex glaberrimus. ramulis tenuibus; foliis verticillatis, 3- 

 vel 4-natis, oblongo-lanceolatis, utrinque angustatis, acutis vel 

 leviter acuminatis, nervis utrinque 6 vel 7, tenuibus, distinctis;
