(74) P. longieaule C. DC. Rec. Bot, Surv. Ind. vi. 11; Journ. 
/Is. Soc. Beng. l.c. 315. 
Spreading climber, glabrous, slender. Leaves rather stiffly 
membranous elliptic-lanceolate to nearly ovate shortly acute-acu¬ 
minate, base quite round or shortly narrowed, slightly oblique; 
nerves from base 7; nervules transverse, slender broken up, all 
elevate; 4 to 5 in. long, 2-5 to 3 in. wide; petioles 75 to 1 in. 
long. Peduncles 1 in. long, slender. Male spikes over 6 in. long. 
Female spikes slender, 3 to 10 in. long; rachis hairy or glabrous. 
Flowers in distant whorls or clusters, often bisexual. Bracts large, 
adnate, ovate-oblong, hairy. Drupe ovate, narrowed at base, 
sub-acute, small. Hab. Forests, Malacca (Maingay). Perak, 
Tapah (Wray); Ulu Slim (Kunstler). Penang (Curtis). Distrib. 
India. 
Probably a variety of the preceding. There is very little difference 
between this and P. leptonema, and they grow together in Penang. The 
difference in the bracts is the only one I see.

(75) P. umbellatum Linn. Sp. PL 43. Pothomorphe subpeltata 
Miq. Syst. Pip. 213; Illustr. 29, t. 26. 
Shrub about 4 ft. tall, glabrous except leaves. Leaves ovate- 
reniform acute deeply unequally cordate, 6 to 12 in. long and 
about as wide, sub-glabrous above, pubescent tomentose; nerves 8, 
radiating from base; petioles 4 to in. long. Spikes crowded on 
the top of axillary branchlets pendulous white, 2-5 in. long, rather 
thick. Flowers bisexual. Bracts peltate. Stamens 2 or 3. 
Ovary free with 3 stigmas. Fruit minute. Hab. In rocky woods, 
common, Pahang, Kwala Tembeling. Selangor, Batu Caves; 
Ginting Bidai; Semangkok (common here). Negri Sembilan, 
Bukit Sulu (Cantley). Perak, Kamuning; Waterloo (Curtis); 
Thaiping Hills. Penang (Wallich); Kelantan, Kwala Aring 
(Yapp). Distrib. S. India, Ceylon, Malay isles, Africa and South 
America. Native name : Sigumber Urat. 
Cultivated only or Excluded Species. 
Piper nigrum Linn. Black Pepper. Lada hitam. Native of 
S. India, cultivated in Penang as early as 1796. 
P. longum Linn. Cultivated in Java, and the dried fruit spikes 
imported here. The plants referred to this by C. DC. Journ. 
/Is. Soc. Beng., l.c. 310 are doubtless something else. 
P. clypeatum Wall. Cat. 6655 A. & B. A climber on tree- 
trunks with distichous orbicular-ovate cordate rounded sub- 
sessile leaves, hairy, 1-5 to 4^5 in. long, 1 to 4-5 in. wide. It 
is common all over the forests, but what it turns into no one 
has discovered. It is probably not a pepper, but a Ficus.
