Folia et pars inferior culmi desunt. Summitas plusquam pedalis. Culmus crassitie pennse columbinae, 

 alternatim canaliculatus, lsevis. Genicula glabra. Vagina! longae, lanceolatse, compressse, folio terminantur 

 angusto acuminatissimo complicato glabro glaucescente. Pedunculi axillares gemini; quorum alter brevior 

 et simplex; alter longior iterumque divisus. Vagina proprise communi similes, lamina autem multo minori, 

 quandoque omnino deficiente, margine membranacese, pallide rufescentes, glabrae. Machis lutescens; arti- 

 culi ejus extrorsum, pedicelli utrinque basin versus longe ciliati. Spicula sessilis 2 lineas longa, lanceolata, 

 flavescens, glabra, setis gluma; inferioris (ubi adsunt) gluma sua paullo brevioribus superioris seta eadem 

 longiori recurva : seta flosculi fertilis fere pollicaris, scabra, infra genu fuscescens. Spicula pedicellata, 

 gluma inferior oblongo-lanceolata, purpurascens, decemnervis, superius ciliata; superior alba, subfimbriata; 

 seta glumae inferioris 3-4 lineas longa, superioris seta 1 J-2 linearum est.

[Roxburgh in his Flora Indica states, concerning the leaves, " those of the root or lower'part of the culm are 

 much longer than the culm, tapering equally towards each end;" and as his observations were made on the 

 living plant, we suspect that Nees has taken his description from herbarium specimens only: at the same 

 time, Rumphius' figure can scarcely be our plant; perhaps it is a true species of Saccharum.]

Of this, which seems to be very common about Macao, we have not received the leaves. It appears to 

 be a remarkably tall plant, and the panicle is very similar to that of 5 1 . officinarum, from which, however, it 

 differs by the large and conspicuous valvelets of the fertile floret. S. procerum differs by the upper valvelet 

 of the bisexual floret.
