3. U. sanguinea, Oliver in Journ. Linn. Soc. ix. 153, partly. 
A delicate terrestrial herb, 4-5 in. high. Stolons filiform, up to more 
than 1 in. long, sparingly and remotely branched, apparently white and 
somewhat fleshy in the fresh state, showing a dark axile vascular strand 
when dry. Rhizoids capillary, 2—3 lin. long from the base of the scapes. 
Leaves in small rosettes at the base of the scape, and, scattered, on the 
stolons, present at the time of flowering, blades somewhat fleshy, orbi- 
cular to obovate-elliptic with a short cuneate base, 1-2} lin. long; 
petioles 1-3 lin. long, or those of the rosette leaves very short: bladders 
from the stolons, leaf-blades and petioles, not very numerous, on slender 
stalks of often more than half their length, subglobose, } lin. long, 
mouth 2-lipped, lips fimbriate, upper rather large orbicular, lower very 
Short. Scape straight, filiform, simple, 2—4-flowered ; flowers distant ; 
bracts ovate, 4 lin. long; bracteoles lanceolate, about as long as the 
bracts ; pedicel up to } lin. long. Sepals subequal, 1}—2 lin. long, 
rotundate-elliptic, obtuse. Corolla very bright blood-red purple, 5-6 lin. 
long; upper lip over 2 lin. long, base broad, blade occupying about half 
of the lip, obovate to broad-oblong, subtruncate; ‘ower lip broad 
cuneate-rotundate, 3 lin. long, deflexed, palate raised, slightly 2-crested, 
crests faintly tubercled ; spur cylindric, rather longer than the lower 
lip, descending. Anthers about 4 lin. long. Capsule globose, 1} lin. in 
diam.; seeds (not quite mature) truncate-pyramidal or conic, top flat 
elliptic or orbicular with a narrow margin.—Hiern in Cat. Afr. PI.

Distinguishable from the similar U. livida by the long and apparently fleshy 
stolons, larger, more persistent leaves, larger bladders with longer stalks, almcst 
blood-red flowers with a wide-open, scarcely tubercled palate. 
4. U. tribracteata, Hochst. in A. Rich. Tent. Fl. Abyss. ii. 18. 
A delicate dwarf terrestrial herb, including the inflorescence 14—3 in. 
high. Stolons finely filiform, much branched, forming small matted 
tufts ; rhizoids numerous from the base of the peduncle, 3-4 lin. long. 
Leaves few at the base of the scape or scattered or in very small tufts 
from the stolons, usually decayed at the time of flowering; blades 
spathulate-cuneate, 14-3 (rarely to 4) lin. long, rarely more than 4 lin. 
broad, gradually passing into the long (up to 5 lin.) and very slender 
petiole. Bladders from the leaves (particularly the petioles) and stolons, 
globose-ovoid, up to } lin. long, on a very short or somewhat longer 
(over } lin.) stalk, mouth distinctly 2-lipped, lips fimbriate, lower lip 
much smaller than the upper. Peduncle straight or nearly so, filiform, 
simple, 4—1-flowered, the flowers of 3—4-flowered specimens scattered 
over the upper half of the floral axis ; bracts and bracteoles very 
similar, equal, lanceolate, acute, up to $ lin. long, lowest bracts often 
barren ; pedicel about as long as the bracts or ultimately exceeding 
them. Sepals subequal, about 14-1} lin. long, obtuse, the upper
