connate about twice as far as the length of the calyx-lobes; 

 anthers glabrous on the back, two of them bearded at the tip, 

 rather exceeding the undivided portion of the larger corolla-lip. 



Hdilla.— In damp sandy pastures on the Humpata plateau, very 

 rare ; fl. April 1860. No. 1140. 



This is perhaps nearly related to L. incmspicua A. Rich., the type of 

 which I have not seen, but it appears distinct by the scapelike stem, 

 «tc. The root, though apparently annual, is possibly not really so and 

 inay be similar to that of X. pusilla. 



3. L. pusilla Welw. ms. in herb. 



A slender, dwarf herb, about 2 in. high ; root seemingly annual, 

 but perhaps persisting longer than a year after the fashion of 

 some species of Drosera ; leaves radical, rosulate, broadly oval or 

 obovate-oval, rounded at the apex, somewhat narrowed at the 

 base to the short or very short petiole, denticulate-repand, sub- 

 glabrous above, more or less pubescent beneath with long whitish 

 hairs, |- to I- in. long; stems scapiform, terete, geminate or 

 solitary, puberulous, erect, simple below, usually once divided 

 above, 2- or 1-flowered, usually sparingly bracteate ; pedicels f to 

 ■f in. long ; bracts small, few, alternate or subopposite, obtuse, 

 inserted on the stem or its forking or on the pedicels, puberulous ; 

 flowers nearly ^ in. long, deep blue; calyx minutely puberulous, 

 campanulate and ^ in. long in flower, more oblong and ^ to i in. 

 long in fruit, somewhat narrowed towards the base especially in 

 fruit ; the lobes lanceolate, acute, about -^ in. long or rather 

 shorter; corolla bilabiate, the lobes of the larger lip connate 

 more than twice the length of the calyx -lobes ; anther-tube some- 

 what pilose on the back, about equalling the undivided portion of 

 the larger coroUa-lip ; two of the anthers bearded at the tip. 



HuiLLA.^In swampy sandy willow-beds, on the left bank of the 

 Tiver Quipumpunhime, between MumpuUa and Nene, sparingly ; fl. and 

 fr. Oct. 1859. No. 1139. 



This is very nearly related to L, gracillima Welw., but differs by sub- 

 sessile leaves, inflorescence, etc. 



4. L. benguellensis Hiern, sp. hov. 



A herb, 4 to 5 in. high ; rootstock apparently perennial ; stem 

 abbreviated, terete, somewhat branched, shortly pubescent ; leaves 

 fiubradical, obovate-oval, rounded at the apex, wedge-shaped to- 

 wards the base into the petiole which is about half as long, obtusely 

 paucidentate or repand, thinly scattered with whitish pilose hairs 

 ■on both faces, -^ to f in. long; inflorescence 3- to 7-flowered, 

 terminal or quasi-terminal, glabrous or nearly so ; pedicels slender, 

 unequal, ranging up to f in. long, erect or suberect, bracteolate 

 at the base; common peduncle scapiform, 2^ in. long, erect or 

 ascending, sub-tribracteate : bracts alternate, sublinear, |^ to J in.
