MERRILL. 
A peculiar genus, anomalous in the family, here reported from the Philippines 
for the first time; apparently widely distributed in the Archipelago, but variable. 
The genus contains the above species, Siphonodon australe Benth., and 8 . pen- 
dulum Bailey, of Australia, and the following species, which is evidently 
undescribed. 
Siphonodon pyriformis sp. nov. 
Arbor parva, glabra, 5 ad 6 m alta; foliis coriaceis, nitidis, oblongo- 
ellipticis vel oblongo-lanceolatis, 7 ad 15 cm longis, basi acutis, margine 
obscure crenulatis; nervis utrinque 7 ad 1.0; fructibus pyriform ibus, ca. 
3 cm longis, crustaceo-carnosis, glabris. 
A small tree, 5 to 6 m high, glabrous throughout. Branches and 
branchlets terete, dark-reddish-brown, lenticellate. Leaves alternate, 
coriaceous, glabrous, elliptical-oblong to oblong-lanceolate, rarely ellip- 
tical-ovate, 7 to 15 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, pyriform, about 3 cm long, 2 cm in diam- 
eter, shining; seeds scattered.

August, 1906; Bur. Sci. 2875 M earns, April, 1907. 
A species allied to the preceding, readily distinguishable however by its 
pyriform fruits. 
ICACINACEAE. 
STEMONURUS Bluine. 
Stemonurus laxiflorus (Miers) comb. nov. 
Platea laxiflora Miers in Ann. & Mag. Nat. Hist. II 10 (1852) 111. 
Qompliandra laxiflora Vidal Rev. PI. Vase. Filip. (1885) 103. 
Cissus flexuosa Turcz. in Bull. Soc. Nat. Mosc. 3 1 1 (1858) 415. 
The species is enumerated here to call attention to the reduction of Cissus 
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 
Cuming 891 that we have seen. Miers’ name having priority, is here retained, 
but is transferred to Stenomurus, where the species apparently belongs. Plan- 
chon in his monograph of the Ampelideae 4 remarks concerning Cissus flexuosa 
“Est-ce bien un Ampelidee? Plus que douteux.” 
Stemonurus merrittii sp. nov. 
Arbor 10 ad 12 m alta, inflorescentiis ramulis petiolisque puberulis; 
foliis papyraceis, obovato-ellipticis vel obovato-oblongis, acuminatls, ca. 
20 cm longis; cymis axillaribus, 1 ad 2 cm longis; floribus sessilibus, 
fasciculatis ; filamentis brevibus, glabris; fructibus anguste oblongis, 
2 ad 2.5 cm longis, plus minus triangulari-compressis, sulcatis.
