 22 CONTRIBUTIONS TO THE FLORA OF SOUTH AFRICA. diam. ; alro oblongsB obtusissimaB glabrae, vexillo duplo breviores; carina incurva, alis vix longior ; ovarium oblique lanceolatum pilosum 6-ovulatum; legumen (an maturum?), 2-5 cm. longum. Hab : South-western Region ; Cape Colony : on the mountain near the village of Piquetberg, alt. 250 met., fl. Oct. Bolus (No. 7523). A very interesting species, remarkable amongst its congeners by its broad verticillate calloso-cihate and gland-striped leaves. It has a near ally in A. lanata, E. Mey. (which was collected in the same neighbourhood by Drege, in the leaves of whose specimens I found also the same narrow glands), but in that the leaves are linear and entire. J. /«/crttfl, Benth., belongs to the same group, but in this the calyx is very different. Indigofera Guthriei, n. sp. (§ Simplicifoli^). — Fruticulus humilis erectus vel decambens ramosus, 6-10 cm. altus ; rami gracillimi foliati glabri ; stipulae e basi lata setaceae, 2-2*5 mill, long^e ; folia brevissime petiolata oblanceolato-linearia, utrmque angustata, mucronata, internodiis longiora, juniora tenuiter stri- gosa demum glabrescentia, l'5-2-5 cm. longa, 2-2-5 mill, lata, marginibus involutis, superne pallidiora ; racemi pauci recti, laxe 2-5-fiori, foUis l|-2-plo longiores, bracteis setaceis mini- mis, pedicellis calyce brevioribus ; calyx turbinatus strigoso- hispidulus, 3-3'5 mill. longus, segmentis acumiuatis tubo 2-3-plo longioribus ; corolla externe villosa 8 mill, longa, partibus sub- aequilongis ; vexillum orbiculare vel ovatum acutum unguiculatum, carina acuta; ovarium lineari-teres glabrum ; legumen maturum hand visum. Hab : South-western Region ; Cape Colony : Hottentot' s-holland Mts., near Sir Lowry's Pass, alt. 460 met., fl. Jan. -Feb., F. GuthrU; Bolus (No. 7509). A small smooth shrublet allied to I. simpllcifolia, Lam. (from Sierra Leone and Angola) ; but appears to differ in habit, as well as by its involute leaves, longer racemes, and smaller flowers, which are coloured pink. It may also be near to I. Kraiissiana, Meisn. (of which Harvey has omitted all mention in the Flor. Cap.), but which has shorter and broader leaves, and an obtusely lobed calyx. Indigofera psammotropha, n. sp. (§ Unijug^). — Annua?, vel biennis?, humilis decumbens, 10 cm. alta, basi ramosa vix lignosa; rami simplices subangalati pubescentes laxe foliati, ad 20 cm. longi ; stipulse setaceae 2-3 mill, longae; folia heteromorpha utrinque strigosa, inferiora minora petiolo communi 1 cm. longo foliolis oblongis integris obtusis 1-1-2 cm. longis, superiora gra- datim majora ad 7 cm. longa, petiolo communi 1*9-4 cm. longo, petiolulis 1 mill, longis, foliolis oblongis lanceolato-oblongisve integris inciso-dentatisve subobtusis mucronulatis, terminali ad 4 cm. longo, 4-6 mill, lato, lateralibus minoribus ; racemi axillares, petiolis duplo breviores, 3-5-flori, pedunculis 4-6 mill, longis, pedi- cellis brevissimis ; calyx turbinatus strigosus, segmentis setaceis tubq subaequilongis ; corolla glabra, 4-5 mill, longa, calycem 2-3- plo superans ; legumina erecto-patentia lineari-oblonga subturgida
