The outer or lower glumule of the neuter floret is as long as, and similar to, the calycine glumes : the 

 upper one is very minute and rounded. 



6. Panicum tenuifolium ; glabrum, culmo ramoso, foliis convolutis, ligula ciliseformi 

 brevi, panicula coarctata, glumis subsequalibus acutis nervosis, floris neutri glumula supe- 

 riori subnullo. 



Culmus glaber, erectus, 1-1 \ pedalis, ramosus, rigidus : nodi glabri. Folia angusta, exsiccatione convo- 

 luta, glabra : vagina striatula glabra : ligula brevissima ciliata. Panicula 3-5 uncias longa, strict!, erecta ; 

 rami flexuosi 'scabri, ramulis ultimis brevibus. Spicules in apice ramulorum solitariae. Ghana calycime 

 glabrae, subsequales; inferior paullo longior, lanceolata, acuminata, 5-nervosa, superior ovata, 7-nervosa. Floris 

 neutri glumula inferior gluma? calycina? superiori omnino similis, superior minutissima; glumulte corollinu' 

 hermaphroditi sequales, albidse, nitidse, cartilaginese, glabra?, neutro breviores. 



This is allied in habit to Agrostis tenuifolia, M. B. as figured by Trinius, Spec. Gram. fasc. 3. n, 35 ; but 

 is a true Panicum. 



1. Orthopogon compositus; spiculis multifloris, floribus geminis hirsutis, glumis ambabus 

 aristatis, exteriori parum majori, interioris arista abbreviata, flosculo neutro mucronulato, 

 foliis lanceolatis. Brown, Prodr. Fl. Nov. Holl. p. 194. Spreng. Syst. Veget. v. I. p. 306. — 

 Panicum compositum. Linn. — O. compositus, var. Trin. Spec. Gram. fasc. 16. t. 188. 



1. Stenotaphrum glabrum; sinubus racheos bi-quinquefloris, spiculis absque rudimento 

 inter flosculos. Nees ah Esenb. — Trin. Fund. Agrost. p. 175. Nees ab Esenb. Agrost. Bran, 

 p. 92. — Rottboellia dimidiata. Linn. 



Our specimens are of the variety with two flowers in each recess of the rachis. Rottboellia complanata, 

 Sw., and R. stolonifera, Poir., also belong to this genus. Stenotaphrum appears to have little affinity with 

 Rottboellia, and ought to come near to Panicum, in which latter genus Linnaeus placed S. complanatum. 



1. Pennisetum calyculatum. Spr. — Fide supra, p. 72. 



Found in Oneeheow. 



1. Vilfa Firginica; paniculae lanceolate contractae densae, ramis approximatis sparsis 

 racemoso-compositis, gluma inferiori valvulis parum breviore, superiori eas aequante vixque 

 superante mucronulata, culmo ramoso, foliis distichis patulis convoluto-subulatis glaucis, 

 collo utrinque barbato. Nees ab Esenb. — Pal. de Beauv. Agrost. p. 16. Nees ab Esenb. 

 Agrost. Bras. p. 400. — Agrostis Virginica. Linn. 



1. Eragrostis variabilis; culmis erectis simplicibus, vaginis foliisque glabris convolutis 

 rigidis collo barbatis, panicula ramosissima, ramis fasciculatis, spiculis 3-14-floris oblongis 

 vel linearibus, palea exteriore acuto-mucronata glumisque dorso denticulato-hispiduJis 

 rarius glabris. Gaud, in Freyc. Foy. p. 408. 



Of this, Gaudichaud enumerates three varieties, our specimens approaching most to bis var. a. culmn 

 procerrimo, panicula diffusa ; but all those in the Collection, although the stem be tall, have the panicle 

 contracted. 



1. Eleusine Jndica; culmo compresso basi repente ramoso, vaginis ore saepiusque el 

 margine villosis, spicis digitatis strictis, spiculis subsexfloris. Nees ab Esenb. — Gartn. —
