Amiprophosmethyl-treatment for polyploidisation in Lobelia

Amiprophosmethyl-treatment for polyploidisation in <i>Lobelia</i>

Ethnopharmacology in the work of the British botanist Arthur Francis George Kerr (1877 - 1942).

Reports on traditional use of medicinal plants may be used as starting points for phytochemical and pharmacological research. As has recently been shown, publications, letters, diaries and reports of exploring botanists are a valuable source of historical ethnopharmacological information. In this study, the heritage of the British botanist Arthur Francis George Kerr (1877-1942), mainly working in Thailand, was screened for information about traditionally used medicinal plants. Information given was compared to state-of-the-art scientific knowledge about these species. Many historical uses could be confirmed, some did not, while a number of species reported to be traditionally used have not been sufficiently investigated so far. These, strongly suggested for further research, include Kurrimia robusta, Alpinia siamensis, Amomum krervanh (A. testaceum), Trichosanthes integrifolia (= Gymnopetalum scabrum), Croton cumingii (= C. cascarilloides), Lobelia radicans (= L. chinensis), Willughbeia sp., Nyctanthes arbor-tristis, Pluchea indica, Heliotropum indicum, as well as some fungi and woods.

pedicelli glabri. Calyx 2-5-3 mm. longus, lobis lanceolato-linearibus, 3- vel 4-glanduloso-dentatis, extus pilosis. Corolla 5-6 mm. longa, extus pilosa; lobi acuminati, ventrales intus papillati basique callis 3 vel 4 longitudinaliter obsiti. Stamina connata, connectivo dorsaliter papillato, imberbe. Ovarium globosum, glabrum, stylis glabris; stigmata margine papillata. Fructus globosus, glaber. Semina obovoidea, sectione transversa sub-triangularia. Small herb, prostrate, with a glabrous, up to 12 mm. long stem. Leaves alternate, I -5-2"5 cm. long; limb ovate or ovate-elliptic, 7-12 x 5-7 mm., rounded or broadly cuneate at base, wavy along margins and with distinct, pear-shaped glands, obtuse or rounded at apex, coriaceous when alive, glabrous on either side, pilose along margin; petiole up to II mm. long, pilose in apical part only. Flowers chocolate coloured, axillary and terminal; pedicels up to 6 mm. long, glabrous. Calyx 2-5-3 mm. long; lobes lanceolatelinear, I-I -5 mm. long, usually with 3 glands on the teeth along the margin, pilose on outside. Corolla 5-6 mm. long; tube 2-2.5 mm. long, pilose on outside, dorsally split to I mm. from the base; free part of all lobes c. 3 X 3 mm., acutely acuminate; ventral lobes on inside with dark purple papillae and near the throat also with 3 or 4 longitudinal crests. Stamens c. 3 mm. long, entirely connate; filaments glabrous; anterior anthers 1.5 mm. long, the posterior ones c. I mm.; all connectives papillate, not barbate at tips. Ovary globose, c. I mm. across, glabrous; style glabrous; stigmas dark purple, papillate along the margins. Capsule globose, 2.5-3 mm. across, glabrous, thin-walled; seeds obovoid, c. 0-7 mm. long, subtriangular in cross-section, smooth.
