CASSIA petersiana Bolle [family LEGUMINOSAE-CAESALPINIOIDEAE], in Peters, Reise Mossamb. Bot. 1: 13 (1861); L.T.A.: 633 (1930); T.S.K.: 61 (1936); T.T.C.L.: 97 (1949); U.O.P.Z.: 179 (1949); I.T.U., ed. 2: 60 (1952); Steyaert in F.C.B. 3: 508 (1952); K.T.S.: 102 (1961); F.F.N.R.: 119 (1962). Type: “Mozambique, Querimba I. and Mozambique”, Peters (B, holo.†. A specimen at Kew (lower valley of R. Shire, Meller) is annotated as having been compared with the original specimen of C. petersiana)
Information
Shrub or tree 0.6–12 m. high. Bark rough, fissured. Branchlets from subglabrous to densely pubescent or sometimes tomentose. Leaves: petiole eglandular; rhachis with a prominent projecting but rather caducous gland between some or all of the 4–10(–13) pairs of leaflets. Stipules conspicuous, leafy, semi-cordate to reniform, often caudate-attenuate at one end, to 2.5 cm. long, ± persistent. Leaflets lanceolate or ovate-lanceolate, sometimes ovate or ovate-elliptic, almost symmetrical, (2–)2.8–10.3 cm. long, (0.7–)0.9–4.2 cm. wide, gradually ± acuminate, rarely acumen obscure and short. Racemes corymbose, aggregated into ± corymbose terminal panicles. Sepals rounded at apex. Petals bright yellow, obovate, 1.5–3.2 cm. long, unequal, the largest somewhat oblique and dentate-margined. Stamens: 3 with large anthers and long filaments, 4 with medium anthers and short filaments, 3 with small rounded anthers and short filaments. Pods ± compressed, linear, 12–25 cm. long, 0.9–1.5 cm. wide, indehiscent, the valves ultimately breaking away from the prominent and transversely cracked sutures. Seeds many, somewhat compressed, ovoid or suborbicular, 5–7 × 4–6 mm., brown, with an olive areole ± 4–5 × 2.5 mm. on each face or marginal.
Range
DISTR. U1–4; K3, 5; T1, 4, 6–8; Z eastern Africa from Ethiopia and the Sudan Republic southwards to Mozambique and the Transvaal, extending westwards to Central African Republic (Haut-Ubangi) and Cameroun Republic; also in Madagascar
Altitude range
12–2130 m.

Notes
VARIATION. Occurring over an extensive range of habitat and altitude, this widespread species is very variable. Although some of the variants show a correlation with geography, they do not seem sufficiently clearly defined to justify their being given names. In East Africa there are three principal ones: 1. With subglabrous stems and leaflets. On Zanzibar and in the neighbourhood of the Tanganyika coast usually at low altitudes up to about 300 m. (though Schlieben 4076, from the Uluguru Mts. at 1400 m., is this variant). Greenway 5169, Vaughan 1326 and 1341 all belong here, and also no doubt the type of C. petersiana. 2. With the stems ± densely pubescent and the lower surface of the leaflets varying from thinly appressed-hairy to rather densely pubescent. The commonest form in Uganda, Kenya and Tanganyika from about 300 m. upwards. All the Uganda and Kenya specimens cited above belong here, as does Watkins 405 in F.H. 3095 from Tanganyika. 3. With the stems and lower surface of the leaflets tomentose. Restricted to S. Tanganyika, between about 200 and 1400 m. alt. Examples are: Mbeya District, Mbozi-Abercorn road, near frontier, 30 Mar. 1932, St. Clair-Thompson 1117 !; Rungwe District, Bulambia, 15 Mar. 1913, Stolz 1946 !; Kilwa District, Madaba, 20 June 1932, Schlieben 2480 ! This variant is C. petersiana var. tomentosa Bak. f., L.T.A.: 634(1930).Particularly in territories to the south of the Flora area perplexing intermediates occur between the above three categories, together with other variations (e.g. forms with small narrow leaflets in the Transvaal and Mozambique) that are absent from East Africa. Milne-Redhead & Taylor 10354, cited above, is intermediate between categories 2 and 3.Further evidence is required about the pods of the three variants described above. Those of (1) are usually narrow, up to about 1.1 cm. wide, while those of (2) are often up to 1.3–1.5 cm. wide, but the material is insufficient and it is not always certain whether the pods available are really mature.The bracts of C. petersiana vary very greatly in width, from lanceolate to reniform, sometimes in the same inflorescence. Pairs of glands, rather similar to those on the leaf-rhachis, occur on the inflorescence-axis, occupying the position of stipules in relation to the bracts.
