478 XCIV, LENTIBULARIE (STAPF). | Viricularia, 
The varieties dryoides and nematoscapa, admitted by Hiern, represent hardly 
more than states differing iu the colour of the corolla and in size, and come entirely 
under the description which Welwitsch gave of his No, 253. 
7. U. linarioides, Welw. ex Oliver in Journ. Linn. Soc, 1x. 151. 
A slender terrestrial herb; rhizoids filiform, very much branched. 
Leaves obovate-spathulate, attenuated into the long slender erect 
(though weak) petiole, usually decayed at the time of flowering ; green 
blade over 1 lin. long, }—? lin. broad; petiole about 5—3 in. long. Pitchers 
unknown. Scape stoutly filiform, 8-16 in. long, erect, straight or 
flexuous, simple or very sparingly branched, with distant lanceolate 
basifixed small scales, up to 6-flowered. Flowers distant by less than 
their own length; bracts and bracteoles lanceolate, not quite a line 
long, subequal, pedicels shorter than the bracts. Sepals equal, orbicular, 
concave, about 1 lin. in diam., thin, yellow. Corolla 6-74 lin. long 
(from the tip of the upper lip to the end of the spur), intensely purple 
with a yellow palate; upper lip broadly ovate to subquadrate, slightly 
emarginate, 2 lin. long; lower lip very broad, semiorbicular, slightly 
wavy, 34-4} lin. long, palate with 2 low smooth ridges; spur slender, 
acute, usually more or less descending, about 4 lin. long. Anthers 
4 lin. long. Stigma subsessile; upper lip ovate-lanceolate, shorter 
than the very broad depressed-orbicular lower lip. Capsule and seeds 
unknown.—-Hiern in Cat. Afr. Pl. Welw. i. 787.  U. linearioides,

8. U. Welwitschii, Oliver in Journ. Linn. Soc. ix. 152. An 
annual, very slender, terrestrial herb. Rhizoids capillary, more or 
less branched. Leaves usually decayed at the time of flowering, loosely 
rosulate at the base of the scape and scattered on the rhizoids, elongate- 
spathulate, very narrow, very gradually passing into the long petiole, 
with it up to over 2 in. lonz, } lin. broad. Pitchers ovoid, narrowed 
at the mouth, } lin. long; upper lip ovate, with 4—5 short rigid hairs ; 
lower lip a naked rim. Scape filiform, more or less flexuous, } to more 
than 1 ft. high, simple or sparingly branched, with few lanceolate seales, 
1 lin. long. Flowers distant, 5-16; bracts and bracteoles subequal, 
lanceolate, acuminate, 3 lin. Jong; pedicel not or scarcely exceeding 
the bracts. Sepals equal, orbicular, very concave, 1 lin. long. Corolla 
23-34 lin. long (from the tip of the upper lip to the end of the spur), 
purple or blue with a deep yellow palate; upper lip broadly ovate, 
entire or nearly so, about 14 lin. high ; lower lip semiorbicular, broader 
than long, wavy; palate broad, smooth, ridges broad and Jow; spur 
rather slender, conic, straight or curved upwards, usually descending, 
2-3 lin. long, densely and minutely papillose. Anthers about 1} hn. 
long. Pistil bottle-shaped with a very short stout neck; stigma sub- 
sessile ; upper lip small, broadly triangular ; lower lip truncate, broad 
and short. Capsule globose, 1 lin. in diam, Seeds angular-globose-
