444 XCII. SCROPHULARIACE.E (HEMSLEY AND SKAN). [PseucloSOpuMa.- 



This species is characterised by having tall, straight, almost unbranched stems. 

 Possibly this and our P. ambigua may eventually have to he reduced to P. Hilde- 

 brandtii, Engl., hut it seems preferable to keep them apart at present rather than 

 risk confusing several species under one name. 



7. P. obtusifolia, Engl, 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 ovatedanceolate, 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, hibracteolate pedicels, about 

 -j- in. long and as much across the top. Bracteoles linear or almost 

 hiiform, about as long as the calyx-tube. Calyx campanulate, 2|— 3 lin. 

 long, hispid at first, lU-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 — 0.

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 or 

 nearly empty. Style elongated, thickened or iiattened at the apex. 

 Ovules numerous in each cell. Capsule ovoid, ellipsoid or subglobose, 

 often somewhat compressed above, refuse, 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 in
