[The one spikelet is sessile, the other pedicellate ; of both, the upper valvelet of the fertile floret is from 

 two to three times shorter than the lower or awned one : the awn is twisted and flexuose.] 



2. E. Japonicus; panicula (racemo composito) apice fastigiata, spiculis pilos involucri 

 strictos grisescentes subasquantibus, glumis glabris, seta flexuosa, foliis lineari-ensifor-

Hab. In insula Lappas ; G. H. Vachell, n. 31. b. 



Gramen altum, rigidum, orgyale. Involucrum spicularum patulum, e pilis rectis haud ita mollibus griseo- 

 albidis spicula paullo longioribus. Gluma exquisite acutatse, lseves, straminese, glabrae ; inferior 2i lin. longa, 

 superior paullo brevior. Seta 4-5 lineas longa, tenuis, pallida, superiora versus flexuosa. Quibus observatis, 

 quomodo differat ab E. versicolore, patet. 



[To the above may be added :— Gluma inferior planiuscula, binervis ; superior dorso convexa vel potius 

 subcymbiformis, trinervis, nervis extus fere obsoletis intus satis conspicuis, margine ciliata. Flosculi superioris 

 valvule? inferior bifida cum arista flexuosa torta, superior in exemplis nostris plane deficiens. Spicula 

 gemini : una breviter (H ''"•)- al *era recurvo-patula longiuscula (H-2 lin.) pedicellata, pedicello utriusque 

 glaber.— Thunberg found this in Japan ; we have it also from Otaheiti.]

1. S. villosus ; repens, foliis lineari-lanceolatis pilosis basi longe ciliatis, nodis vaginisque 

 villosissimis, spica bifida, spiculis rhombeo-ovalibus, gluma inferiori basi convexa lasvis- 

 sima a medio depressa (in spicula pedicellata compressa) stricta anguste marginata biden- 

 tata, superiori subulato-acuminata, seta flosculi (dorsali) spicula duplo longiori, rhachi 

 triquetra alternatim semifurcata gerniniflora angulis poriformibus, articulis pedicellisque 

 breviter ciliatis.

Perquam similis est S. obliquivalvi, N. ab E. (qui Ischcemum aristatum, Roxb., non Lin., et I. cihare, 

 Retz, at non Arthraxon ciliare, P. B.) sed bene distinctus inter confines vaginis nodisque pilis longis mollibus 

 patentibus dense villosis, gluma superiori subulato-acuminata, nee bidente cum brevi apiculo interjecto, seta 

 longiori fortiori, spiculisque majoribus et rhachi triquetra. Folia 3-4 pollices longa, duas lineas lata, acumi- 

 natissima, supra pilosula, et circa margines inferius longe ciliata. Spicmramus alter brevis. Spicula 2 fere 

 lineas lata?, glabrae : gluma margine scabra? ; inferior a basi ad medium lsevis in parte depressa striataque 

 ssepe transversim subrugosa aut lacunosa ; superior paullo longior. Seta e dorso valvulae medio infra incisuram 

 egressa, 4 lineas longa, a basi ad geniculum purpureo-fusca.

 1. A. (Trachypogon) punctatus ; spicis paniculatis, rhachi ciliata infra spiculas bar- 

 bulata, spiculis margine ciliatis, utraque supra medium dorsum foveola profunda pori-
