168 MR. H. N. RIDLEY ON THE WEST-AFRICAN 
S. JUNCIFORMIS, Welw. MSS.; rhizomate repente crasso lignoso, squamis ovatis striatis 
tecto, radicibus rubris; culmis seriatis bipedalibus validis triquetris striatis glabris ; 
foliis linearibus acute carinatis longis, inferioribus raro hispidulis ; vaginis integris 
striatis ore albo-ciliatis, inferioribus purpurascentibus, angulis longe ciliatis, superio- 
ribus glabris; panicule ramis paucis triquetris suberectis, fasciculis compositis ; 
spieulis linearibus glabris pallide sanguineo-maculatis vel sanguineis; bracteolis 
spiculis brevioribus, ovatis mucrone longo ; squamis inferioribus lanceolatis breviter 
mucronatis, supremis lanceolatis acuminatis; caryopsi globulosa trigona minuta 
alba brevissime mucronata. 
Huilla, in pratis sylvaticis alte graminosis, prope Catumba, no. 7138; in pratis 
paludosis ex Monino ad Eme, frequens, no. 7139, Jan.-Mart. 1860. 
This species is closely allied to Sel. erythrorrhiza, but is distinguished by the tuft of 
white hairs at the mouths, and the long white cilia on the angles, of the vaginæ, the 
paniculate arrangement of the inflorescence, and the glabrous spikelets with entire lanceo- 
late acuminate glumes. The rhizome is, as in that species, covered with ovate scales, the 
parenchyma of which decaying away leaves the fibro-vascular bundles. The rhizome is 
yellow, and resembles that of Juncus balticus, Willd. ; Ше culms are somewhat distant, 
and 2-21 feet in height; the leaves on the culm are 6 inches in length, excluding the 
vagina, and nearly always glabrous. 
S. USTULATA, n. sp.  Glabra 1-1i-pedalis, radicibus fibrosis; culmis erectis paucis 
gracilibus triquetris foliatis; foliis angustissime linearibus obtusis, 3—6-pollicaribus 
striatis; vaginis plerumque glabris, rarius minute hispidis, integris purpureo-punc- 
tatis ; spica semipedali ; fasciculis 12-18, approximatis; spiculis 1 9 ‚1—2 с in fasciculo; 
bracteola lineari longe acuminata, viridi, lateribus dense atro-sanguineo maculatis ; 
squamis lanceolatis acuminatis; carina viridi, lateribus supra atris, infra ochraceis, 
sanguineo-maculatis ; .caryopsi globosa trigona brevissime mucronata, papillosa 
echinulata alba. 
Pungo Andongo, in Andropogonetis humidis sylvestribus ad ripas fluminis Cuanza 
una eum Droseris, Mart. 12, 1857, по. 7134. Non czspitosa, spicis e flavo, fusco et nigro 
variegatis. 
The alliance of this plant is with S. hispidula, Hochst.; but it differs in being almost 
completely glabrous, with broader leaves and lanceolate acuminate glumes, conspi- 
cuously tipped with very dark purple or black. The culms are slender, and one to 
three on a plant; the spike of fascicles is 6 inches in length, and overtopped by the last 
cauline leaf. The nut is one line in length. 
S. PULCHELLA, n. sp. ; radicibus fibrosis rubris copiosis; culmis pluribus erectis triquetris 
glabris rarius hispidulis; foliis linearibus acutis complanatis, marginibus et carina 
hispidis, triuncialibus ; vaginis integris, ore membranaceo, striatis purpureo-punctatis; 
spica raro composita, unciali; fasciculis approximatis ; bracteola pallida ovata longe 
acuminata, acumine scabro, lateribus scariosis; rhachide flexuosa, acute triquetra ;
