Lepidagathis differs by the anthers all 2-celled, the stigma subequally minutely 
2-lobed, and the presence of bracteoles. N. subuninervius, Kurz, has been removed 
to Lepidagathis. 
* Spikes axillary, elongate, bracts sub-A-ranked. 
l. N. trinervius, Wight Ic. t. 1532; leaves sessile elliptic cuneate at 
both ends nearly glabrous, bracts ovate or obovate spinous-mucronate ð- 
nerved, calyx-segments linear-lanceolate long-ciliate. Dalz. & Gibs. Bomb.

Stems 1-3 ft., glabrous except at the tips. Leaves 44 by 13 in., lineolate above, 
sometimes minutely setose. Spikes 1-5 in., hairy; bracts $ by à in. Calyx à in. ; 
segments divided about half-way down; cilia } in., rising from minute glistening 
tubercles. Corolla } in., blue, nearly glabrous without, 2-lipped ; segments 5, sub-

2. N. tetragonostachyus, Nees in Wall. Pl. As. Rar. iii. 97, and 
Cat. 7168, and in DC. Prodr. xi. 248; leaves short-petioled elliptic or 
obovate-lanceolate attenuate at both ends thinly pubescent or glabrous, 
bracts elliptic spinous-mucronate 5-nerved, calyx-segments linear-lanceolate 
long-ciliate. 7. Anders. in Journ. Linn. Soc. ix. 494.

Hardly differs from N. trinervius except in the greater attenuation of the leaves 
at both ends. Flowers blue (Parish). 
3. N. grandiflorus, Kurz in Journ. As. Soc. 1873, pt. ii. 95 ; leaves 
small obovate or oblong subobtuse nearly glabrous, bracts ovate-lanceolate

Leaves 1} by 3 ìn., not lineolate, minute scabrid-pubescent (in Kurz's specimen) ; 
Petiole obsolete. Corolla } in., or rather more, blue.— Exceedingly near N. tetragono- 
stachyus, but has much smaller leaves, and larger flowers. — Neuracanthus sp. (Kew 
Distrib. n. 6144), collected by Griffith in Hookhoom Valley, Upper Burma, is perhaps 
à variety, but has the leaves closely pubescent beneath. 
** Spikes axillary, densely capitate, bracts not 4-ranked.
