С. CALLISTUS, n. sp. Herba ex bulbillo oriens, bulbillo castaneo tunicato ovato acuto 
radicibus fibrosis tenuibus ; culmo singulo 4-5-pedali crassiusculo triquetro canalicu- 
lato ; foliis viridibus linearibus longe acuminatis strictis eulmum subeequantibus mar- 
gine scabriusculis, vaginis membranaceis fissis ; involucralibus 6-8 patentibus demum 
reflexis longissimis linearibus, longe acuminatis basi vix dilatatis; umbella magna, 
radiis valde inæqualibus; spiculis linearibus 7- vel 8-floris patentissimis aureofulvis ; 
bractea ad basin sæpius longissima acuminata; ocreis truncatis semiuncialibus ; 
squamis linearibus oblongis obtusis remotiusculis, carinatis multistriatis ; stylo brevi

squama duplo breviore. 
Loanda, ad stagna in herbidis prope Quicuxe, parce, Martio 1857, no. 7079. 
A remarkable plant of the Diclidium section. According to Dr. Welwitsch it attains 
4 or 5 feet in height; his specimens, however, are only about 2 feet. The plant springs 
from a bulbil, like that of С. bulbosus, Vahl. The leaves are long and rather flaccid, 
and the involucrals attain a length of 8 inches. The rays of the large umbel are about 
11 in number, the longest measuring 5 inches. 
C. EURYSTACHYS, n. sp.; rhizomate descendente; culmis erectis validulis elatis subtri- 
quetris striatis, basi subbulbosis ; vaginis subefoliatis fissis striatis purpurascentibus ; 
involucralibus 9-linearibus viridibus complanatis carinatis, pedalibus, basi latis, 
erectis demum reflexis; radiis umbelle, circiter 12, valde ineequalibus, alteris 
longis biuncialibus patentibus, alteris ferme sessilibus; осгеіѕ oblique truncatis 
ampliatis striatis; spicis ovatis, spiculis copiosis patentibus vix compressis quadri- 
floris; squamis lanceolatis appressis 10-costatis, dorso viridi, costis pallidis, lateribus 
pallide sanguineis; stylo longo trifido profunde exserto rufo; caryopsi oblonga 
trigona leviter arcuata, lateribus excavatis, squama dimidio breviore, rufescente, 
punctata; rhacheola flexuosa late alata fragili, alis scariosis.

ad finem Aprilis 1850, no. 7061. 
The affinity of this plant is with С. Meyenianus, Nees. It is remarkable for the 
absence of leaves at the base of the culm. The culm is three feet in height; the involu- 
сга] bracts, very unequal in length, attain a length of 12 inches, and are t inch in diameter. 
The spikelets are rather loosely aggregated into ovate spikes $ inch in length, the inferior 
ones on peduncles 14 inch long. They consist of four perfect flowers, and are 33 lines in 
length. Тһе ocree are 2 lines long. The glumes are 10-ribbed, the keel green, and the 
space between the ribs pale red. 
С. TANYPHYLLUS, n. Sp. (tavrdvdAcc=longifolius.) Czespitosns, rhizomate brevissimo vix 
repente ; culmis 1—2-pedalibus, triquetris canaliculatis, basi subbulbosis ; foliis linea- 
ribus flaccidis culmo brevioribus ; vaginis integris chartaceis brunneis ; involucralibus 
5-7 longissimis viridibus flaccidis linearibus basi haud dilatatis, marginibus et costis 
scabris; umbella 5—ll-radiata, radiis pollicaribus striatis ; spiculis remotiusculis 
patentibus lanceolatis acuminatis subteretibus 4-floris; squamis ovatis breviter
