Throughout India, alt. 0-4000 ft., from the Himalaya to Ceylon and Malacca, 

 common : not in western desert India. — DiSTElB. S.E. Asia, Australia, Africa,

Stems mostly short, with petioled leaves often 4-8 in. long j flowering stems trailing, 

 1-3 ft., with subsessile leaves J-2 in. Spikes 4-2 in., mostly sessile, terminal on 

 lateral branches j bracts ^-J in., obtuse, herbaceous. Calyx ^ in., green, striate, 

 hairy or snbscarious. Corolla J in. Ovm^t/ and style glabrous. Capsule ^-^ in., 

 8-12-seeded. Seeds yellowish with brown granulations. — The picture of the seed by 

 Kippist in Trans. lAnn. Soc. xix. t. 6, fig, 11, showing the surface with hammer- 

 headed spines, is erroneous.

 10 in., uppermost 3-5 in. ; petiole 2 in. JBracts elliptic, acute: — Dr. King says that 

 it is very easy to distinguish this from every form of N. campestris, but that he can 

 give no good character for it, and that it had better be regarded as an extreme form 

 of that plant. Koxburgh says the capsule is 4- or S-seeded ; it is really as that of N. 

 campestris type.
