DO FEN.EACE.^ (Stephens). [Founsa. 



12. P. dubia (E. L. Stephens in Kew Bulletin, 1910, 237) : erect 

 branched undershrub, about 1 ft. high (?) ; branches minutely 

 scabi^ous ; leaves erect, sessile, ovate or elliptical, acute or mucronate- 

 ^cute, with dorsal nerve obscure except at the extreme base, 2|-3|- 

 lin. long, 1^-2 liii. broad, exstipulate, with 1-2 minute brown setffi 

 at each side of the axil ; flowers lateral, sessile; bracts of the form 

 and size of ordinary foliage leaves; bracteoles 2 pairs at the base 

 of the flower ; outer pair at right angles to the leaf, semicoriaceous, 

 -concave, oblong-acute or mucronate ; inner pair parallel with the 

 leaf, membranous, ovate, acuminate-acute ; tube of persistent 

 perianth (at fruiting stage) 3 lln. long ; lobes erect to one-third of 

 their length, then reflexecl, deltoid, acute, 1 lin. long; ovary in 

 fruit slightly rough, with ill-defined projections ; style llliform, 

 scabrous, minutely tuberculate, with 4 small obscure horizontal 

 ridges at its base, which alternate with the cells and are sometimes 

 bifid by a continuation of the furrow between them ; apex of style 

 not seen; seeds 2 in each cell, basal.

The affinities of this species are doubtful, the solitary specimen being in the 

 fruiting stage and showing neither the stamens nor the upper half of the style. 

 I have placed it next P, ericifolia because of the projections at the base of the 

 ;style, which may correspond to the more definite ridges at the base uf the style in 

 that species. Its general habit is that of a small-leaved P, orata, but in its 

 inflorescence it resembles the three preceding species. In the number and form 

 of its bracts it approaches P. fruticulosa, and its perianth is that of P. ericifolia 

 except for the'reflexed lobes — a point which, however, is probably not important^ 

 ■as the perianth-lobes in any species of Pcniva may occasionally reflex in the 



fruiting stage. 



Imj)€rfecilu known species. 



13. P. macrosiphon (Gamlog. in Bull. Soc. Bot. France, Ix. 420, 



1913) ; an undershrub about G in. high ; stems simple ; leaves imbri- 

 cate, straight not spreading, ovate, cuspidate, rounded (not sheathing) 

 ■ at the base, about 3 liu. wide, midrib prominent beneath; flowers 

 about 5 lin. long, pedicellate. 



Coast Region : Cape Div. ; Eetrait near Cape TowU; Bonoml, 



Allied to P, mncronata^ Linn., from which it is distingui.slied by its larger size 

 and erect, not spreading, leaves. 



II. BRACHYSIPHON, A. Juss. 



Periantli'tule cylindrical or ovate-cylindric, nearly twice as lung 

 •as the limb or subequal to it, longer than or subequal to the 

 bracts ; lobes erect or reflexing only in the faded flower, 

 reduplicate-valvate in bud. Stamens shorter than the perianth- 

 lobes ; filaments very short ; anthers as long as the filaments, with 

 cells adnate on a thick lubed connective and usually shorter than 

 it. Ovarii and styjc at first as long as the perianth-tube, latei* 

 surpassing it; ovary four-angled, glabi'ous or minutely scabrous; 

 ■ovules 2 or 4 in each cell, basal, erect (in B. rttpeslns occasionally
