154 CLXXIII. GRAMINEJE. (J. D. Hooker.) [Rottboellia. 



narrowed from the middle upwards; II more or less usually wholly adnate to the 

 joint, IV very short or 0. Pedicelled spikelets, gl. I 7-uerved ; II $- in., keel 

 excentric. Very nearly allied to JR. compressa. " The only Androp. grass in which 

 fruiting spikelets are not detached, hence there can be no dissemination except from 

 the whole spike," Hackel. The Laccadive Islds. specimens are very slender with 

 narrow leaves and quite erect strict lanceolate finely acuminate spikelets, rather 

 longer than the joints. 



Var. Hamiltoniana ; callus of sessile spikelets bearded with short hairs. ? R.

 Steud. I.e. 359. Lower Gangetic Plain; Natlipur, Hamilton. Referred to com- 

 pressa by Hackel, but I thiuk nearer to protensa. 



5. TEL. longriflora, Hook. f. ; spikes short, rachis firm, sessile spikelets 

 -% in. lanceolate narrowed into a long point, callus obscure, gl. II rather 

 longer subaristate, pedicelled spikelets like the sessile. 



TENASSEBIM ; at Mergui, Griffith. ASSAM, Herb. Munro. 



Stem 12 ft., erect, leafy, stout, spongy ; nodes glabrous or pubescent. Leaves 

 3-6 by -- 1 in., linear-lanceolate from a rounded base, flaccid, smooth, glabrous, 

 margins smooth; sheath inflated; ligule short, membranous. Spikes 4-6 in., 

 sheathed below, stout, nearly in. across the spikelets; rachis subtetragonous. 

 Spikelets twice as long as the joints, the pedicelled rather longer and longer awned 

 than the sessile ; gl. II adnate to the joint; III of sessile spikelet oblong, obtuse, 

 nerveless; IV like III, palea small. Lodicules quadrate, broader than long, 

 membranous. Gl. IV of pedicelled spikelet narrower than the sessile, paleate, with 

 imperfect stamens and pistil. Resembles a very large state of R. protensa. 



Sect. IV. PELTOPHORUS and CCELORHACHIS, Hack. Spikes solitary or 

 fascicled, fragile, terete or compressed ; joints transversely (rarely obliquely) 

 truncate, deeply hollowed, dorsally convex, ventrally excavate; pedicel of 

 upper spikelet free or adnate to the joint of the rachis, tip hollowed.

* Gl. I of sessile spikelets broadly winged.

 verse ridge. Hack. Monogr. Androp. 290. Manisuris Myurus, Linn. Mant.

Stem creeping and rooting, with ascending compressed branches 6-28 in. high. 

 Leaves 2-6 in., spreading, linear, acute, flat, glabrous; sheath compressed, margins 

 ciliate ; ligule short, ciliate. Spikes 1-2 in., solitary, terminal and axillary, shortly 

 exserted ; joints scaberulous, shorter than the spikelets, excavate on each side leaving 

 a pore between the spikelet and joint. Sessile spikelets ^ in., brown, callus minute ; 

 gl. I scabernlous, 5-nerved, wing scarious ; II ovate, acute, 3-nerved ; III oblong, 

 obtuse, empty ; IV lanceolate, nerveless ; palea obsolete. Pedicelled spikelets ; gl. I 

 oblong, obtuse, 5-nerved, winged on one side; II navicular, 3-nerved; 'III 3-nerved, 

 paleate ; IV oblong, obtuse, male; pedicel free or adnate. to^the joint.
