A peculiar genus, anouialmis in tlic family, licrc reported from (lie Pliili|)pines 

 for the first time-, apparently widely distributed in tlic Archipelago, hut variahle. 

 The genus contains the above species, Siphonodon ouslrule Jicnth.. and »S'. pen- 

 ilulum Bailey, of Australia, and the following spetdes, whiidi is evidently 

 luidescribed. 



Siphonodon pyriformis sp. nov. 



Arbor parva^ glabra, 5 ad (» iii alt;i ; I'oliis coriaccis, iiitidis, obloiigo- 

 ellipticis vel oblongo-lanceolatis, 7 ud 15 cin longis, basi acutis, inargine 

 obscure crennlatis; nen'is iitriiuiiic 7 ad lO: fnictibiis pyrifonnibus, ca. 

 3 cm longis, criistaceo-caniosis, glabris. 



A small tree, 5 to 6 m high, glabrous throughout. Brauches and 

 branchlets terete, dark-reddish-bi*own, lenticellate. Leaves alternate, 

 coriaceous, glabrous, elliptical -oblong to oblong-lanceolate, rarely ellip- 

 tical-ovate, 7 to IT) cm long, 3 to 6 cm wide, the base acute, apex shortly 

 and obtusely acuminate or rather long acuminate, the margins obscurely 

 crenulate; lateral nerves 7 to 10 on each side of the midrib, irregular, 

 anastomosing, the secondary ones nearly as prominent; petioles 4 mm 

 long or less. Fruit axillary, solitary, the peduncles 5 to 8 mm long, 

 crustaceous-fleshy, glabrous, pyi-ifoi-m. about 3 cm long, 2 cm in diam- 

 eter, shining; seeds scattered.

A species allied to the preceding, readily distinguishable however by its 

 pyriform fruits.

The species is eiuimerated here to call attention to the reduction of Viasus 

 flexuosa Turcz., it being based on the same number of Cuming's collection as was 

 Platea laxiflora. Turczaninow's description also applies to the specimens of
