Names
TOUSSAINTIA orientalis Verdc. [family ANNONACEAE], in K.B. 25: 2, fig. 1 (1971). Type: Tanganyika, Ulanga District, Ifakara, Haerdi 410/0 B (K, holo.!, EA, iso.!)
TOUSSAINTIA sp. nov. [family ANNONACEAE], sensu Haerdi in Acta Tropica, Suppl. 8: 38 (1964)
Information
Straggling small tree or shrub; young branchlets dark at first, pubescent with brown hairs, later somewhat scabrid with short blackish hairs or glabrescent. Leaf-blades elliptic, 1.5–9.5 cm. long, 1–5.7 cm. wide, obtuse to shortly mucronulate at the apex, cuneate to rounded at the base, rather thick, green and often minutely black-speckled above, dull and whitish beneath due to clusters of white deposits within the epidermal cells, glabrous above, adpressed pubescent beneath when young, becoming sparsely so with age; venation very closely reticulate and raised on upper surface; petiole 1 .5–3 mm. long. Flowers rather small, so far known only from almost mature buds, in 1–3-flowered leaf-opposed fascicles; peduncles obsolete or scarcely 0.5 mm. long; pedicels 0.7–1.2 cm. long, ferruginous pubescent; bracts and bracteoles elliptic, 3–4.5 mm. long, 1.5–2 mm. wide, ferruginous pubescent. Sepals raised at edge so that buds are conspicuously 3-ribbed, broadly lanceolate, 1.1 cm. long, 5–5.5 mm. wide, ferruginous pubescent outside. Petals in 2 rows of 3, the aestivation open at extreme base, oblong-elliptic, 8–9 mm. long, 4 mm. wide, tomentellous outside, glabrous inside. Androgynophore 3.5 mm. high; anthers 0.7 mm. long, very numerous. Carpels ± 16; ovary linear-oblong or subcylindrical, ± 2 mm. long, ± 11-ovulate, densely hairy; stigma well developed, lobulate. Very immature monocarps ellipsoid, ferruginous pubescent. Fig. 1, p. 9.

Altitude range

Distribution
TANGANYIKA Uzaramo District Banda Forest Reserve, Nov. 1964, Procter 2735! & same locality, 16 Aug. 1968, Shabani 189!;TANGANYIKA Ulanga District near Ifakara, Aug. 1960, Haerdi 410/0 B!
Notes
Haerdi’s specimen was mixed with Artabotrys monteiroae Oliv. and also a third specimen which may perhaps represent more mature leaves of the above. They are certainly black-speckled and reticulate above and paler beneath but differently shaped, narrowly oblong-elliptic, up to 11.5 cm. long, 4.5 cm. wide, with a petiole 4 mm. long. Further material is much needed; it is only because it is so distinctive that such inadequate material has been described.
