[The plant which we have joined as var. /3, to that described by Nees von Esenbeck, diiFers from it in no 
respect except in the more branched inflorescence : the structure of the spikelets being identical in both. On the 
other hand, w'e see few grounds for separating the more luxuriant or more perfect form, and which is by far 
the most abundant in our collection, from A. montanus, Roxb. ; Roxburgh, however, describes the leaves as 
“ long and narrow,” and figures even the uppermost one close to the panicle, and 6 or 8 inches long, while 
in our plant it is very short and subulate ; Roxburgh, moreover, does say that the lower glume of the fertile 
spikelet is channelled on the back, which could scarcely have escaped the notice of N. von Esenbeck. 
Var. a has much the appearance of A. leptostachys, Wight and Arn., (or A. sacchar aides, Roxb., and 
n. 890 of his drawings at the India House), but in that also the uppermost leaf is elongated and similar to 
the lower ones, and the branches of the inflorescence seem constantly alternate, simple, and bearing a single 
slender spike that is fully more than an inch and a half long. We have received both a and /3 from Prof. 
Henslow', under n. 50 of Mr. Vachell’s collection ; Mr. Millett has only sent the var. (3.]

Differt ab A. Schcenantho spiculis duplo minoribus. Ab A. pachnode, Trin., non solum spiculis paullo 
minoribus 1 ^ lin. vix longis, sed etiam gluma inferiori spiculse fertilis distincte 4-5-6-nervi et seta multo breviori, 
gracili, valde flexuosa, lineas longa, turn foliis angustioribus et ligula breviori. Bractece purpurascentes ; 
communis pedunculos binos breves distachyos promens. Spicce vix 3-4 lineas longae. Spiculce virides, 
structure omnino ut in A. Schcenantho. — Rarni 1-2 axillares erecti, vaginati, vaginis ramulos breves fascicu- 
latos (geminos) alios simplices pedunculos exhibentes, alios compositos bracteis bi-distachyis praeditos pro- 
mentibus, unde ramus paniculae singulos racemum angustum exhibet. 
5. A. (Cymbopogon) coesius ; culmo procumbente erectove ramoso nodis foliisque 
lineari-acuminatis ctesio-glaucis Isevibus et glabris, spicis geminis fasciculato-paniculatis 
bracteatis bracteis spicas aequantibus, rhachi pedicellisque albo-hii'sutis, spicula fertili 
oblongo-lanceolata, gluma inferiori 2-4-nervi margine superiori carina albo-membranacea 
serrulata, valvula fertili bifida laciniis filiformibus, mascula pedicellata mutica, gluma 
inferiori octonervi acuta, pedicello crasso. — a; gluma binervi. N. ab E. in Wight Cat,

Probabiliter hie est A. hirtus Indise orientalis, de quo verba facit Thunbergius in FI. Capensi. Differt 
culmo plerumque dififuso cum vaginis foliisque laevissimo, his brevioribus, 2-3 pollices longis, acuminatissimis, 
bracteis laevibus, spicis brevioribus, spiculis glabris, solisque pedicellis rhachique albo-hirsutis. Spiculce lan- 
ceolatae, virides. Flosculus neuter in spicula, tam mascula quam fertili, univalvis, conspicuus, glumis paullo 
brevior, valvula lanceolata acuta ciliata. Valvula fiosculi hermaphroditi linearis, ad ^ bifida, laciniis 
filiformibus, e sinu emittens setam spicula plus duplo longiorem scabram ; superior valvula deest. Lodiculae 
truncatae, bidentatae, complicatas, genitalia amplectuntur. Stamina 3, antheris sordide luteis. Stigmata lutea. 
Spicula: mascula flosculus perfectus evalvis, lodiculis valvularum vices gerentibus. Gluma spiculce sessilis
