5. P. Wightiana, Mig. in Hook. Lond. Journ, Bot. v. 948; suberect, 
rather slender, glabrous or with the tips of the leaves ciliolate, leaves 
opposite and alternate petioled obovate elliptic oblong or orbicular obtuse, 
3.nerved, spikes 1-3 usually terminal. P P. Wightiana, Cas. DC. in Prodr. 
xvi. 1. 420. P. ceylanica, Mig. l. c. 550; Cas. DC. l c. 497. .

CEYLON, Walker; Central Province, alt. 6000 ft., Thwaites (C. P. 3954). 
Stems 6-10 in., straggling and rooting below, glabrous or puberulous. Leaves 
}-1 in., very variable, rarely obovate, succulent, glabrous except at the tip; petiole 
3-4 in. Spikes 1-2 in., very slender, sometimes paniculate.— Cas. DC. describes the 
stem as pubescent, but it is glabrous in authentic specimens (in Herb. Arnott), aud 
Miquel does not describe it as pubescent. Wight’s figure is, I think, taken from 
P. dindigulensis. I suspect this is only a variety of P. Heyneana. Specimens 
from the Nilghiris have all the leaves alternate. Miquel’s P. ceylanica has most 
minute pubescence on the branches; the leaves are chiefly opposite. 
6. P. dindigulensis, Mig. Syst. Pip. 192, in Hook. Journ. Bot. v- 
549, and Ill. Pip.19, t. 13; stem and leaves pubescent, leaves opposite 
rarely alternate or 3-nately whorled petioled elliptic-ovate or rounded obtuse 
or acute 3-5-nerved, spikes slender axillary and terminal solitary or panicled.

Deccan PENINSULA ; from the Concan southward, in the moist ghats. 
Very variable, sometimes 18 in. high, with a stem as thick as a goose-quill and 
suberect, at others more slender and straggling; stem simple or branched. Leaves 
1-1} in., succulent, narrowed into the petiole. Spikes 1-3 in. long.—I find nothing 
answering to Wight’s figure of P. Wightiana in his or Arnott's Herbarium ; its alter 
nate leaves resemble P. Wightiana, but the hairiness is that of P. dindigulensis. His 
figure of P. dindigulensis represents a glabrous plant, unlike any species I have seen; 
but for its opposite leaves I should refer itto P. Thomsoni. I have seen no specimens 
of P. Thwaitesii, Cas DC., but the description entirely accords with P. dindigulensis. 
7. P. portulacoides, 4. Dietr. Sp. Pl. i. 172; quite glabrous; 
tufted, stem very stout branched and suceulent, leaves opposite or the 
upper whorled petioled obovate or subrhomboid tip rounded 3-nerved, spikes 
stout longer than the leaves axillary and terminal. Mig. Syst. Pip. 130, 
and in Hook. Lond. Journ. Bot. v. 550; Cas. DC. in Prodr. xvi. 1. 449; 
Wight Ic. t. 1922. P. Candolleana, Mig. Syst. 146. Piper portulacoides,

. Stem erect from a creeping base, sometimes as thick as a swan's quill, leafy. 
Leaves all opposite, 1-2 in. long, very variable in width and thickness, very succulent ; 
petiole j-3 in. Spikes 1-2 in., axillary and terminal. 
Var. courtallensis ; smaller, leaves narrower. P. courtallensis, Miq. in Hook. 
Lond. Journ. Bot. v. 594; Cas. DC. in Prodr. xvi. 1. 463. Courtallam, Wight.—! 
see no material difference between this and P. portulacoides; and they inhabit the 
same locality.

creeping and rooting, leaves subsessile succulent opposite and 3-nately 
whorled oblong obtuse 3-nerved narrowed at the base, spikes axillary 4?
