allied to both Amorphophallus longistilus Kurz, of the Andaman Islands, 
and to A. harmandii Engl. & Gehrm., of Cambodia, but differing from 
both in many characters. It is at once distinguished from the former by 
its much smaller spathes, and from the latter by its larger spathes and 
relatively much longer spadices. 
AMORPHOPHALLUS DECURRENS (Blanco) Kunth Enum. 3 (1841) 581; 
Engl, in DC. Monog. Phan. 2 (1879) 319, Pflanzenreich 48 (1911) 
108 = AMORPHOPHALLUS CAMPANULATUS (Roxb.) Blume! 
Kunth’s Amorphophallus decurrens was based on Arum decurrens Blanco 
FI. Filip. (1837) 656, and is retained by Engler, in his recent monograph 
of the group, among the doubtful and imperfectly known species. In all 
characters Blanco’s description applies very closely to Blume’s species, 
which is very common and widely distributed in the settled areas throughout 
the Archipelago. There is no reason whatever for doubting that Arum 
decurrens Blanco, that is, Amorphophallus decurrens Kunth, is identical 
with the older Amorphophallus campanulatus (Roxb.) Blume.

Planta dense casepitosa, inflorescentiis exceptis glabra; caulis

longis, basi brevissime vaginantibus ; pedunculis numerosis, 5 
ad 18 cm longis, gracilis, leviter tortis, 5-costatis ; capitulis sub- 
globosis, circiter 5 mm diametro, in siccitate nigris, bracteis al- 
bido-ciliatis ; floribus $ sepalis 3, connatis; petalis nullis vel 1 
ciliato-fissis ; antheris nigris; floribus $ exacte trimeris, sepalis

A densely csespitose plant, glabrous except the inflorescence. 
Stems stout, short. Leaves numerous, densely crowded, lanceo- 
late or narrowly lanceolate, 2 to 6 cm long, 5 to 8 mm wide, about 
10-nerved, much wider at the base than above, gradually nar- 
rowed and usually obtuse. Peduncles numerous, slender, up to 
18 cm in length, 5-ribbed, slightly twisted. Heads subglobose, 
4 to 5 mm in diameter, nearly black or somewhat grayish when 
dry, dense, the involucral bracts pale, oblong to obovate, truncate, 
about 2 mm long. Receptacle glabrous. Floral bracts dark- 
colored, oblong-oblanceolate to oblong-obovate, shortly acum- 
inate, distinctly white-ciliate toward the apex on the back. Male 
flowers: Calyx about 1.5 cm long, dark-colored, spathelike, at 
first 3-toothed, the lobes eventually becoming free nearly or quite 
to the base, eglandular. Petals none, or one only and ciliate-cleft 
into several hyaline- jointed segments. Stamens 6 ; anthers black. 
Center of the flower with 3 minute, dark-colored sessile glands. 
Female flowers: Sepals 3, subequal, oblanceolate to oblong, 1.8 to
