setaceis glaucis, culmo multo brevioribus, glabris striatis ; vaginis glabris, ore ciliatis; 
involucralibus 2 glumaceis, capitulo brevioribus; spiculis seepius 4-7 in capitulo con- 
gestis vel in umbella brevi-radiata, parvis lanceolatis acutis; squamis atro-sanguineis 
hispidis, marginibus breviter ciliatis, lanceolatis brevissime mucronatis trinerviis ;

Huilla, in pascuis dumetosis ad oram sylvarum Catumba, frequens, init. Maii, no. 6951, 
in pascuis editioribus ad Empalanca denso agmine tractus longos cum Xyrideis et Asco- 
lepidibus occupans, no. 6950. 
The affinity of this plant is with F. quaternella, mihi. The culms are from З to 6 
inches high, the leaves 1 to 2 inches. The larger plants have usually umbels of about 
4—7 short rays. The spikelets are from 2-3 lines long. 
Е. COLLINA, n. sp. Czespitosa, radicibus fibrosis; culmis erectis sed debilibus vacillan- 
tibus, obtuse triquetris, hispidis, preesertim supra; foliis angustis linearibus acutis 
hispidis, marginibus revolutis, culmo dimidio brevioribus; vaginis membranaceis 
brunneis, ore longe albo-ciliatis; involucralibus duobus setaceis brevibus basi dila- 
tatis hispidis, uno capitulum superante; capitulo singulo, spiculis dense congestis ; 
squamis ovatis lanceolatis, hispidulis mucronatis (mucrone recto), carinatis, atro- 
sanguineis, carina pallidiore; stylo tenui trifido rufo; caryopsi ovata oblonga sub- 
globosa vix trigona alba vel fulva minute cancellata, tuberculo minuto depresso- 
conico.

Golungo Alto, frequens in editis (2200 ped. alt.) montosis, graminibus brevibus et fru- 
ticulis nanis obsitis, ad orientem Quilombo Quiacatubia, no. 7004; in declivibus editis 
montium Queta, по. 70040. Juncum Jacquini simulans, in cespites laxas aggregati. 
This plant is allied to Scirpus vestitus, Reichb., from which it is distinguished by the 
solitary capitulum and larger oblong, less trigonous nut; it is also much more glabrous. 
The culms are from 1 foot to 14 in height, the leaves about 6 inches, the involucral 
leaves very short, the longest only 1 inch long. 
F. CARDIOCARPA, n. sp.; radicibus fibrosis; culmis erectis obtuse triquetris ultrapeda- 
libus glabris; foliis angustissime linearibus acutis, quam culmi multo brevioribus ; 
vaginis membranaceis ferrugineis ore ciliatis; involucralibus duobus basi dilatatis 
glumaeeis longe mucronatis trinerviis capitulum subsequantibus; capitulo singulo 
laxiusculo; squamis ovatis acutis mucronatis carinatis trinerviis, carina lanuginosa 
rufa, lateribus atro-sanguineis ; staminibus tribus; filamentis rufis persistentibus ; 
stylo breviter exserto trifido rufo; caryopsi cordata trigona puncticulata rugosa, 
albescente nitida, quam squama 3 breviore, tubereulo minuto atro depresso.
