444 XCII. SCROPHULARIACEH (HEMSLEY AND SKAN).  [Pseudosopubia. 
This species is characterised by having tall, straight, almost unbranched stems. 
Possibly this and our P. ambigua may eventually have to be reduced to P. Hilde- 
brandtii, Engl., but it seems preferable to keep them apart at present rather than 
risk confusing several species under one name. 
7. P. obtusifolia, Lngl. in Ann. Istit. Bot. Roma, vii. (1897), 28. 
An erect, branching, slightly hispid herb about 2 ft. high ; branches 
suberect, quadrangular, rigid, pubescent; internodes of the flower- 
bearing branches shorter than the leaves or bracts. Leaves and bracts 
opposite, shortly petiolate, rather thick, ovate or ovate-lanceolate, 5- 
7 lin. long, and gradually smaller upwards, obtuse or subacute, slightly 
hispid; venation very obscure. Flowers solitary in the axils of the 
leaves or bracts on very short, slender, bibracteolate pedicels, about 
} im. long and as much across the top. Bracteoles linear or almost 
filiform, about as long as the calyx-tube. Calyx campanulate, 2}-3 lin. 
long, hispid at first, 10-ribbed, alternate, shorter ones obscure; lobes 
ovate-lanceolate, a little shorter than the tube, acute, slightly recurved. 
Corolla hairy outside, glabrous within, veined, cylindrical at the base, 
then suddenly inflated ; limb oblique ; upper lip emarginate ; lower lip 
distinctly 3-lobed, lobes rounded. Stamens included, glabrous; filaments 
filiform; anthers of the lower pair smaller. Ovary and lower part of 
the style clothed with long straight hairs; style very slender, longer 
than the stamens.—Engl. Jahrb. xxiii. 511, t. 13, fig. L—O. 
Nile Land. Somaliland: between the Karanle and Daua Rivers, Riva, 950; 
Lake Rudolph, Wellby! 
Although Capt. Wellby’s specimen does not agree in some small details with 
Engler’s description, there is, we believe, no doubt about its being the same species. 
Why the specific name, obtusifolia, was selected is unintelligible because the author 
describes and figures the leaves as acute. 
51, SOPUBIA, Buch.-Ham. ; Benth. et Hook. f. Gen. Pl. ii. 970. 
Calyx campanulate, 5-toothed or shortly 5-lobed; lobes valvate, 
often deltoid or linear-triangular. Corolla-tube usually short, some- 
times exserted, enlarged at the throat ; limb spreading ; lobes 5, broad, 
entire, subequal, the 2 upper inside. Stamens 4, didynamous, sub- 
included ; anthers all coherent or coherent in pairs, 2-celled ; one cell 
of each anther perfect, ovoid or ellipsoid, often somewhat apiculate, the 
other cell much smaller, linear or clavate, stipitate, quite empty oF 
nearly empty. Style elongated, thickened or flattened at the apex: 
Ovules numerous in each cell. Capsule ovoid, ellipsoid or subglobose, 
often somewhat compressed above, retuse, emarginate or rounded at the 
apex, loculicidal; valves entire or at length 2-fid. Seeds numerous, 
oblong or obovoid or sometimes linear, obtuse or truncate ; testa rather 
loose.—Annual herbs or undershrubs, usually erect and branched, 
glabrous, scabrid, white-tomentose or woolly, often drying blackish. 
Leaves opposite or verticillate or the upper alternate, often linear, 
entire or pinnatifid, with linear or filiform segments. Flowers 1
