SANDWICH ISLANDS. 



[ GraminecB. 



This has many points in common with C. Monti ; but the stem is acutely angular. Each ray of the 

 umbel has on its upper half several horizontal alternate branches, of which the lower are the longest, and the 

 upper gradually shorter. These again, particularly the lower ones, have also alternate branches, along which 

 are placed the turgid spikelets. The stem is from fifteen inches to two feet high. The leaves resemble those 

 of some of the larger species of Curex. 



8. Cyperus Prescottianus ; spiculis linearibus elongatis compressis horizon talibus alternis 

 spicatis, spicis eorymboso-racemosis, squamis hiantibus obtusiusculis nervosis, involucri uni- 

 versalis polypbylli foliolis tribus umbella duplo longioribus, partialibus umbellula brevioribus, 

 culmo acute triquetro. 



There is only one specimen in the Collection. We have named this species in honour of J. D. Prescott, 

 Esq. of St. Petersburgh, who has made the Cyperacem his particular study. 



9. Cyperus multiceps; spiculis subulatis spicatis, spicis umbellatis conf'ertis, umbella et 

 umbellulis intermediis atque ultimis multiradiatis, squamis oblongis obtusis, involucri poly- 

 pbylli foliolis tribus inflorescentia quadruplo longioribus, involucellis umbellulas proprias 

 aequantibus, culmo triquetro. 



Of this only one specimen exists in the Collection. The Howers are not sufficiently advanced to enable 

 us to decide whether it be a true Cyperus or a Papyrus.

2. Panicum gossypimim ; totum dense ac molliter pilosum, foliis planis, panicula ramosa 

 effusa, ramis gracilibus, spiculis lanceolatis, glumis subajqualibus, floris neutri glumula su- 

 periori minimo. 



The silkiness extends not only to the stem and leaves, but to the branches of the panicle and the glumes. 

 The stems grow in a tufted manner. 



3. Panicum affine; caule foliis (planis) vaginisque pilosis, panicula ramosa, ramis erecti- 

 usculis strictis pilosis, spiculis ovatis, glumis pilosis subaequalibus, floris neutri glumula 

 superiori nullo. 



Closely allied to the preceding species, but the panicle is much more glabrous, and the shape of the 

 spikelets is very different. 



4. Panicum nephelophilum ; foliis planis minute pubescentibus basi supra vaginisque 

 villosis, ligula nulla, panicula subcoarctata, ramis strictis erectis elongatis, glumis subsequali- 

 bus acutis nervosis glabris, floris neutri glumula superiori brevi. — Gaud, in Freyc. Voy. 

 p. 411? 



As it appears doubtful whether this is the same as the species discovered by Gaudichaud, we have altered 

 the specific character to what corresponds to our specimens. The hairs on the sheaths of the leaves spring 

 from tubercles, and often fall off on the upper part. It appears to be a tall plant. 



5. Panicum Beecheyi; culmo ramoso glabro decumbente, nodis sericeis, foliis convolutis 

 vaginisque glabris, ligula brevi ciliata, panicula contracta, glumis subaequalibus nervosis 

 pilosis, floris neutri glumula superiori minutissimo.
