СҮРЕБАСЕЖ IN THE WELWITSCH HERBARIUM. 167 
S. BULBOSA, Hochst., var. PALLIDIFLORA; foliis hirtis, marginibus ciliatis; squamis cas- 
taneis; caryopsi alba ferme levi. 
Pungo Andongo, in pratis humidis peculiaribus (e graminosis gracillimis solum coin 
positis), prope Sobata de Muta Lucala, nec alibi a me visa, Mart. 1857, no. 7188; Caricis 
arenarie et affinium habitu; culmus 3- rarius 4-pedalis, erectus. 
In the typical S. bulbosa, a native of Abyssinia, the capitula are almost, if not quite, 
black, the leaves glabrous, with a few hairs on the nerves and margins, and the caryopsis 
is tuberculate, instead of being nearly smooth, as it is in this plant. 
S. casprtosa, Welw. MSS.  Cespitosa, rhizomate breviter repente radicibus copiosis; 
eulmis erectis gracilibus 2- rarissime 3-pedalibus, acute triquetris glabris; foliis 
erectis angustissime linearibus obtusis glabris vel parce pilosulis, vaginis integris 
triquetris vel parce pilosis, ore albo-ciliatis ; spica simplici, fasciculis 11-12 remotius- 
culis; braeteola lanceolata pallida, mucrone longo ciliato ; squamis inferioribus ovatis 
lanceolatis mucronatis, superioribus lineari-lanceolatis acutis sanguineis, carina 
pallida; stylo profunde trifido brevi; caryopsi globosa trigona, alba nitida obtuse 
mucronata, basi angustata triquetra levi. 
Pungo Andongo, frequens in pratis sylvaticis paludosis inter Condo et Quisonde, 
Mart. 1857, no. 7135. 
One of the Dregeana section, nearly allied to S. verticillata, with strict culms and 
leaves, nearly glabrous. A simple spike, one or two inches long, of rather distant 
fascicles of spikelets, generally two together. Тһе highest leaf on Ше culm does not 
overtop the spike. 
S. ERYTHRORRHIZA, sp. n.; rhizomate repente crasso lignoso, squamis ovatis striatis 
secto, radicibus rubris ; culmis pauci-foliatis seriatis erectis pedalibus acute triquetris 
glabris; foliis erectis linearibus complanatis carinatis, marginibus carinaque longe 
albo-ciliatis, vaginis integris inferioribus ciliatis, superioribus glabris ; spica nutante, 
folio supremo superante; fasciculis 7, spiculis in fasciculo 3; bracteolis ovatis oblongis 
pallidis, margine hispido, mucrone longo viridi hispido; rhachilla acute triquetra 
glabra; squamis lanceolatis, inferioribus pallide ocreis sanguineo maeulatis lanatis, 
superioribus sanguineis muticis apice fimbriatis; caryopsi levigata. 
Huilla, in pratis sylvaticis, prope ad basin Morro de Ferrao da Sola, sporadica. 
This plant is related to S. Dregeana, Kunth; it has a stout creeping rhizome, covered 
with ovate pinkish scales; the culms are 14 inches high, the leaves on the upper part of 
the culm are 2 inches in length; they become shorter on the lower part of the culm, 
and pass gradually into those on the rhizome. The glumes are remarkable for the outer 
ones being covered with a whitish pilosity, while the inner ones are fimbriate. There 
were no nuts on the specimen ; but Dr. Welwitsch states that they are smooth.
