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.
Range
DISTR. T6 not known elsewhere
Altitude range
140–260 m.
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.
