468 FLORA OF SOUTH AFRICA. 
10. P. speciosa, Sims, DC. 1. c. n. 17. Ad rivulos in 
Zitzikamma (IV. C. b.) Mart. 1839. Krauss n. 1230. 
11. P. macra, DC. l. c. n. 22?—In solo lapidoso-arenoso 
ad latera mont. Winterhoek, distr. Uitenhage (IV. C. c.) 
May 1839. Krauss n. 1228.—The shortness of De Can- 
dolle's diagnostic phrase, and the want of an ampler descrip- 
tion and figure, will place P. macra among the “species vix 
note,” to be recognised only by autopsy of original speci- 
mens. In the shortness of the leaves (3-6 lines) our plant 
seems to agree with P. macra ; but, in its elongated raceme, 
and pale pink flowers, it approaches more to P. genistoides, 
Poir. from which, perhaps, that species is not sufficiently 
distinct. 
L2. P. genistoides, Poir. dict. 3. p. 492. B. ephedroides, 
Burch, DC.1. c. n. 23 ?—In arenosis prope Kafferkuylsrivier, 
distr. Zwellendam (IV. C. a.) Jan. 1839. Krauss, n. 904. 
—In our specimens, the flowers are pale green, except 
the carina, and especially its fringed crest, which is purple. 
The ale are a little smaller, narrower, and more distinctly 
veined than in our P. macra, which has them 4-4} lines long, 
and nearly as broad, and traversed only by one greenish 
vein. 
13. P. Garcini, DC. 1. c. n. 24. (Burm. Afr. t. 73, f. 3, 
bona.) — In arenosis planitiei Capensis (III. E. b.) Aug. 
1838. Krauss n. 908.—To this belongs also Ecklon's * P. 
bracteata,” Un. itin. n. 39. 
14. P. uncinata, E. Meyer in pl. Drége.—In sylvis prope 
flum. Umlaas, Port Natal (V. c.) Dec. 1839. Krauss n. 
216.—This species which, to our knowledge, has not yet 
been described, may be characterised as follows :— 
Glabra, caulibus basi suffruticosa ramosis, superne sub- 
simplicibus gracilibus ; foliis sparsis, anguste linearibus, 
obsolete mucronulatis; racemis terminalibus, subsecundis, 
rachi pilosiuscula, pedicellis sepala exteriora gquantibus 
patulis demum deflexis; alis obovatis, rotundatis, venosis, 
carinam breviter cristatam occultantibus ; capsula obcordata, 
apice anguste alato-marginata.
