WAHLENBERGIA NODOSA
Hi Evieb,
The info I have for W. nodosa is the below (I've bolded the bits I've found helpful in the past for IDs):
"
A rigid much branched diffuse or erect shrublet, up to 50 cm high though commonly 15—30 cm., the branches often divaricate, the younger branches white or pale-coloured.
Leaves alternate, (often) distant, reflexed, fasciculate, rather thick, ovate-lanceolate, 2—6 mm. long, 1 —1-5 mm. wide, acute, concave above, the edges entire or with minute teeth .
Inflorescence with rigid spreading branches, often spinous in the later phases.
Flowers solitary, 1 —5 to a branch, on slender pedicels 3—7 mm long.
Calyx lobes 2—3 mm. long, acute or mucronate.
Corolla white, fading to yellow, often brownish outside, 5—8 mm. long, the tube very short, the lobes glabrous. Bases of the filaments ovate to lozenge-shaped, densely ciliate.
Style blue, longer than the corolla, shortly hairy, gradually thickened to the top: stigma lobes 3, very short.
Ovary less than half inferior, the lower part rounded or flattened, less than 1 mm. long, about 1-5 mm. diam.
Fruit 5-ribbed, broader than long: valves as long as the calyx lobes, twice as long as the lower part.
The type is EcMon s.n. (Port Elizabeth) in herb. Bonder, (S).
Rocky places in rather dry regions, especially on hills in and around the karroo.
The commonest and most wide-spread species.
Rather variable in habit and in the branching of the inflorescence.
Distinguished by the small reflexed leaves, the branched inflorescence, and half superior ovary. The leaves on the main stem often fall, only the axillary fascicles persisting.
In the past much confused with L. tenella and L. diffusa, indeed Ecklon & Zeyher issued specimens under the latter name.
