﻿428 LENTiBULARiE^ (Stapf). [UtricuUria. 



3. U. Kirkii (Stapf in Hook. Ic. PL t. 2795, fig. C) ; a delicate, 

 dwarf terrestrial herb, including the inflorescence, 1-5 in. high ; stolons 

 filiform, branched ; rhizoids capillary from the base of the peduncles ; 

 leaves scattered on the stolons, often decayed at the time of flowering, 

 blades spathulate-cuneate, up to l^lin. long and i lin. broad, gradually 

 narrowed into the usually long and slender petiole ; bladders on the 

 leaves, ovoid-globose, I lin. long, 2-lipped ; apper lip suborbicular, 

 lower very small, both fringed, month opposite the stalk ; peduncle 

 straight or flexuous, simple, 5-1 -flowered ; flowers rather distant, if 

 4 or 5 scattered over the upper half of the floral axis ; bracts and 

 bracteoles subequal, lanceolate, acute, usually under i lin. long, lowest 

 bracts barren ; pedicels almost as long as or at least somewhat longer 

 than the bract ; sepals 1 liii. long, obtuse (rarely the upper subacute), 

 upper ovate-orbicular to orbicular, lower elliptic ; corolla pale purple 

 with a darker upper lip, l|-2 lin. long ; upper lip constricted below 

 the middle, upper part somewhat fleshy, obovate-oblong to obovate- 

 quadrate, subtruncate; lower lip subquadrate, about 1 lin. long; palate 

 almost parallel lo the upper lip, double crested, crests minutely but 

 distinctly tubereled ; spur 1^ lin. long, suddenly narrowed from the 

 broad conic base into the slender cylindric turned-up more or less 

 obtuse upper half ; style shorter than the stigma ; upper stigma-lip 

 oblong, about i the length of the suborbicular lower lip ; capsule 

 globose, up to over 1 lin. in diam. ; seeds shortly truncate-conic, 

 often angular, top face elliptic or suborbicular, about ^ lin. long, witli 

 a thin margin or a fine shnple rim ; embryo top flat or slightly 

 concave. U. exilis, Kavi. in Engl. Jalirh. xxxiii. 97 (Behmann, 

 6599, not of Oliv.). U. exilis, var. EcUonii, Kam., /.c, 98 {Kirks 

 plant). U. exilis, var. hirsuta, Kam., I.e. 



Kalahari Region : Transvaal ; Hooge Veld, between Porter and Trigards- 

 fontein, Rehmann, 6599 ! Houtbosch, Behmann (?) 1 



Also in Tropical Africa. 



Very pirailar to U. exilis, but distinguished by the tubereled palate. Tbc p'lW 

 is not hairy, as is stated by Kamienski in his description of U. exilis, va ^ 

 hirsuta. The author may have been misled by the presence of an alga w'"*^^j^^ 

 found in the type specimens of this variety to cover a portion of the scapes, 

 same alga, a species of Oedogonium, also occurred under similar conditions on 

 Transvaal specimens. 



Kamienski (in Engl. Jahrb. xxxiii. 110) also indicates U. minor, I^i°"-' f^ 

 found by Bergius in "Kapland," without precise locality. I have not seen i 

 specimen, which is in the Berlin Herbarium. The occurrence of this nortii 

 form in South Africa would, if proved, be very remarkable. 



4. TI. transrugosa (Stapf) ; a delicate terrestrial herb, i°'=^'^'^[?J 

 the inflorescence 4-6 in. high ; rhizoids in tufts at and near 

 base of the peduncle, short and scarcely branched ; stolons, leave 

 and bladders unknown ; peduncle straight or nearly so, ^'^^''^^g 

 simple, 3-1 -flowered; barren bracts few, remote, like the terU^ 

 ovate, about i lin. long; bracteoles somewhat narrower than 

 bracts of about the same length ; pedicels slightly exceeding I ^ 

 bracts; sepals subequal, rotundale-elliptic, suborbicular, 1^-1^ "
