132 A FLORA OF MANILA. 
Typhonium trilobatum (L.) Schott, a native of Ceylon with large, 
deeply 3-lobed leaves, 10 to 20 cm long, and spathes 12 cm long or more, 
its blade purplish and 5 to 7 cm wide has been cultivated in Manila, but 
I have seen no specimens. T. divaricatum Decne. (FI. Filip. pl. 330.), also 
with 8-lobed leaves 4 to 6 cm long, and spathes somewhat similar to the 
above is occasionally cultivated. This species extends from India to Japan 
southward to Malaya, introduced here. 
8. ALOCASIA Schott 
Small to very coarse herbs from fleshy corms, sometimes with a short 
stout caudex. Leaves oblong to ovate, base deeply cordate, peltate or 
not, entire or variously lobed. Spathe erect, peduncled, the tube ovoid, 
the limb usually elongated, deciduous. Spadix shorter than the spathe, 
the male and female flowers usually separated by interposed neuter ones. 
Ovaries 1-celled; ovules few, basal, erect. Berries few-seeded. (Name 
altered from Colocasia.) 
Species 25 or more, tropical Asia to Malaya, many now cultivated in 
other countries for ornamental purposes, about 10 in the Philippines.

5. A. heterophylla 
1. A. sanderiana Bull. 
A small or medium sized glabrous plant from underground rootstocks. 
Leaves oblong-ovate to broadly lanceolate-ovate, acuminate, the base peltate, 
deeply lobed, 15 to 40 cm long, the margins rather deeply undulate-lobed, 
the basal lobes rather narrow spreading; upper surface dark-green, the 
nerves and sometimes the margins white, the lower surfaces usually 
purple or tinged with purple. Peduncles erect, shorter than the leaves. 
Spathes greenish, about 5 cm long. Spadix greenish-white, nearly as long 
as the spathe. 
A very ornamental species occasionally cultivated for its striking leaves, 
a native of Mindanao. Endemic. Frequently cultivated in Europe and 
America. 
2. A. portei (Schott) Engl. & Becc. 
Stem stout, erect, usually less than 1 m high. Leaves green, oblong- 
ovate in outline, up to 1 m in length, deeply pinnately lobed, the lobes 
narrow, oblong to lanceolate-ovate, distant, the base deeply cordate, not 
peltate, the basal lobes narrow, prominently lobed. Spathes peduncled, 
the tube about 4 cm long, accrescent, the blade 20 cm long or more. 
Staminate part of the spadix 4 to 5 em long, cylindric, the appendage up 
to 18 cm in length.
