 392 DECADES PLANTARUM NOVARUM AUSTRO-AFRICANARUM. paulo brevioribus; floribus purpureis, singulis vel geminis termi- nalibus axillaribus, pedunculo tenui strigilloso, folia paulo excedente, pedicello brevi ; calycis segmentis subsequalibus subdeltoideis, acu- minatis, brevissimis, glabris; vexillo subreniformi, apice breviter excisa, glabro, ungue lineari, 0*9 cm. longo, 1*2 cm. lato ; alls graciliter unguiculatis, lamina oblique oblonga obtusa, basi auricu- lata, 09 cm. longis ; carinse petalis alis simillimis paulo majoribus lamina latiore, 1*2 cm. longis, obtusis ; legumine lineari, glabro, apice stylo coronata. In regione austro-orientali : in monte Hangklip, prope Queens- town, alt. 5500 ped., Novembr. 1893, E. E. Galpin, No. 1608. In habit resembling B. tenuifolia E. Z., next to which I propose to place our plant. B. pauciflora is the first species in the genus with almost glabrous leaves. In many respects it resembles Loto- nonis, but the calyx-lobes are nearly equal. The two genera Lotononis (especially the section Krehsia) and Buchenrcedera are so nearly allied that it is nearly impossible to separate them. 4. Cliffortia repens, sp. n. Fruticulus e basi ramosus, decumbens, ramis teretibus elongatis, cortice bruneo, dense foliatis, glabris ; foliis lineari-setaceis mucronatis, dorso subcarinatis, sim- plicibus, tenuissime pilosulis, 0-8-1-5 cm. longis ; stipuhs setaceis glabris, minutis ; ovaris subcylindrico, glaberrimo, subecostato ; calycis segmentis ovatis vel ovato-triangulis acutis, patentibus ; stylo sanguineo valde plumoso, calycem plus duplo excedente. In regione austro-orientali :. in saxosi summi montis Drakens- bergen, ad pontes fluminis Polela, alt. c. 6000-7000 ped., Febr. 1896, M. S. Evans, No. 614. On account of its simple leaves, this species should be placed next to C. pungens Presl, from the Gnadendal and the Winterhoek Mountains. The distinction between these two species lies in the habit and the leaves, which are in C. pungens much more rigid and thicker, besides being rounded on the back and quite glabrous. The stigma in C. repens is very plumose and more cut than I have ever noticed it to be in any other species. I am sorry to say that there are no fruits or male flowers in the specimens before me, but only female flowers, in which the ovaries are almost cylindrical and quite smooth, with the exception of two nerves on one side. From C. juniperina L., which our plant resembles at first sight, it is dis- tinguished by habit and the simple minutely pilose leaves. 5. Wahlenbergia polytrichifolia, sp. n. Herba perennis tenerrima, e basi ramosa, 5-7 cm. alta ; ramis adscendentibus erectisve, foliis setaceo-subulatis, glabris, alternantibus, 1-1-5 cm. longis, tectis ; inflorescentia terminali laxe 2-5-flora ; pedicellis brevibus ; calycis tubo hemisphaerico, glabro, segmentis subulatis, margine sparsim ciliatis erecto-patentibus, glabris, tubo paulo longioribus, 0-3-0'4 cm. longis ; corollas tubo subcylindrico, calycis lobis aequilongo, lobis erecto-patentibus lanceolatis subacutis, 0-3 cm. longis ; capsula ovoidea, glabra, 3-valvata ; stylo filiformi, coroUse tubum conspicue excedente, glabro. In regione austro-orientali : in saxosis in monte Hangklip,
