4. Rottboellia Talboti, Hooh. f. Fl. B. I. v. 7 (1896) p. 155. 

 Annual ; stems 6-8 in. high, slender, erect, or geniculate at the base, 

 lieaves 2-3 by yo~8 "^•' lii^ear, smooth ; sheaths glabrous ; ligule short, 

 membranous. Eaceme |-1^ by \ in., solitary, green ; joints very short, 

 tumid, excavate opposite the spikelet, the top broad, with a very large 

 cavity and thick hispidulous margins. Sessile spikelets g in. long (or 

 more) including the awn, closely imbricating ; callus aniudar, ciliolato 

 Glumes 4 ; lower iuvol.-glume i in. long (not including the awn), 

 coriaceous, lanceolate, narrowed into a slender scabrid awn, with 2-3 

 transverse ridges at the base, the uppermost ridge extending right; 

 across the glume, the others only in its centre, broadly winged at each 

 side above the base ; upper invol.-glume ^ in. long, thinly membranous, 

 ovate-oblong acute, 1-nerved ; lower floral glume broadly oblong, 

 faintly 3-nerved, male ; upper floral glume small, oblong, obtuse, 

 nerveless ; palea as long, nerveless. Pedicellate spihelets as long as the 

 sessile; lower iuvol.-glume very irregularly winged, dorsally smooth, 

 awnless, as in the sessile ; pedicel wholly adnate to the joint of the 

 rhachis. Woodr. in Journ. Bomb. Nat. v. 13 (1901) p. 437. — Mowers:

Goa, Talbot, 2572 ! 



There is but one sheet in Herb. Kew., the specimens on which were collected at 

 Goa by Mr. Talbot. 



The species is allied to R. divc7-gens, from which it differs in the lower iuvol.- 

 glmne of the sessile spikelets, which in that species is 2- in this 1-awned, and in the 

 tumid joints of the rhachis. 



5. Rottboellia Clarkei, Hade in (Estr. Bot. Zeitschr. v. 41 (1891) 

 p. 8. Annual ; stem 8-24 in. high, erect, striate, compressed ; nodes 

 with a small ring of haii's. Leaves 4-6 by \-h in., linear-lanceolate, 

 acuminate, narrowed to the subcordate base, scabrous and more or less 

 hairy, the hairs with minutely tubercular bases; midrib prominent; 

 sheaths compressed, ciliate ; ligule a hairy membrane. Raceme solitary, 

 i-1 in. long, pale yellow, supported by a spat he; rhachis very fragile; 

 joints pyriform, shorter than the spikelets, ciliolate and with a broad 

 cavity at the tip, the sides not hollowed. Sessile spilcelets -j-^-]. in. 

 long, obtuse, closely imbricating ; callus short and broad, cylindric. 

 Glumes 4; lower invol.-glume with an ovate coriaceous 3-5-nerved 

 disk and hyaline wings which are ciliate at the tip, dorsally gibbous, 

 scabrid and hairy below the middle; upper invol.-glume ^ in. long, 

 ovate-oblong, subacute, membranous, 1-nerved, glabrous ; lower floral 

 glume shorter than the upper invol.-glume, ovate-oblong, subobtuse, 

 hyaline, nerveless ; upper floral glume rather smaller than the lower, 

 oblong, obtuse, hyaline, nerveless, the margins incurved ; palea like 

 the glume, nerveless. Pedicellate spikelets imperfect, consisting usually 

 of a solitary empty glume about yV in. long; pedicel quite free from 

 the rhachis, pyriform, flattened, about -^\^ in. long, Fl. B. 1. v. 7,
