Differs from the preceding in the shortly petiolate, larger leaves, 

 which are thinly appressedly villous, and the larger flowers. 



3. P. Atherstonei, sp. nov. P. sessilifolicd valde affinis, sed 

 indumento crassiore, foliolis et spicis longioribus differt. 



Gaides (annul, e radice perenni?) fulvo hirsuti, simplices vel 

 raro parce ramosi, stricti, 0-3 m. longi, lignosi, teretes vel sub- 

 tetragoni, valde foliati. Folia subsessilia aut breviter petiolata, 

 arrecta ; foliola saepissime conduplicata, anguste cuneata vel ob- 

 lanceolata, breviter cuspidata vel apiculata, apicula ad 2 mm. longa, 

 terminalia 20-25 mm. longa, 4-7 mm. lata, lateralia paulo breviora 

 vel aequilonga, coriacea, dorso valde costata, supra fusciora niti- 

 dulaque, margine paullulo incrassata. SinccB terminales, solitaria?, 

 25-40 mm. altae, aliquando secundae et subnutantes. Flares con- 

 ferti, subsessiles vel pedicellis rarius 1 mm. excedentibus suffulti ; 

 bracteola subulata, ad 5 mm. longa. Calyx 7 mm. longus, lobis 

 superioribus fere obsoletis connatisve late deltoideis, lobo inferiore 

 ceteris longiore et subulato, extra breviter fulvo hirsutus, intra 

 magis minusve glabrescens, hirsuto-ciliolatus. Vexilli lamina late 

 oblanceolata, rotundata in unguem longiusculum attenuata, cum 

 ungui 8-10 mm. longa, postice paullulo sericea, alse in toto 

 8 mm. longse, glabrae, limbis oblique oblongis obtusis basin versus 

 in ungues rectos sensim attenuatis ; carina alls similis sed limbo 

 minore et unguibus gracilibus longioribus. Pistillum 5 mm. 

 altum, ovario valde hirsuto, stylo recto glabro. 



Kalahari Eegion. — Transvaal ; near Lydenburg, Ather stone ! 

 {Herb. Keiu). 



This species approximates most closely to P. sessilifoUa 

 Diimmer, but is easily distinguished by the thicker and coarser 

 indumentum, longer leaflets and spikes, which latter are occasion- 

 ally nodding. 



4. P. propinqua, sp. nov. P. Atherstonei valde affinis, sed 

 foliis usque subsessilibus brevioribus baud abrupte cuspidatis, 

 floribus saepius congestis recedit. 



Caules circiter metrales, undique corolla excepta valde fulvo- 

 sericei, stricti, graciles, simplices aut superne ramosi, angulati, 

 dense foliosi. Folia subsessilia ; foliola ascendentia aut patula, 

 anguste cuneata, breviter cuspidata, lateralia ad 13 mm. longa, 

 4-5 mm. lata, intermedia paulo majora, dorso conspicue costata, 

 supra medio canaliculata, nitidula, coriacea. SpiccB terminales, 

 solitariae, hemisphaericae vel cylindricae, 1 cm. altae, 5-multiflorae.
