Sibthorpia
(named after John Sibthorp, 1758-1796, Professor of Botany at Oxford, and the originator of "Flora Graeca"). SYN. Disandra. Including Hornemannia. ORD. Scrophularineae. A genus consisting of half-a-dozen species of greenhouse or hardy, prostrate, hairy herbs, often rooting at the nodes; they are native of Western Europe, tropical and North-western Africa, Nepaul, and South America. Flowers yellow, yellowish-pink, or red, on axillary, solitary or fascicled pedicels; calyx campanulate, four to eight-cleft (often five-cleft); corolla tube short, sub-rotate; lobes of limb as many as, or one more than, the calyx lobes, spreading; stamens as many as, or one less than, the corolla lobes. Leaves alternate or fascicled, petiolate, orbicular-reniform and deeply crenate or incised-toothed. S. europaea (Cornish Moneywort, Pennyleaf, or Penny-wort), comprised in the British Flora, is more curious than beautiful; but the variegated form is a pretty plant, well worth cultivating. The latter requires a light, well-drained soil, and should be grown in a cold frame or cool greenhouse, under a glass. Only one species-S. peregrina-calls for description here. It is a small, trailing, hairy, greenhouse perennial. When raised, its pendent branches and little, yellow flowers assume a very pretty appearrance. It will succeed in any light, rich soil. Propagation may be effected by divisions or by cuttings, with or without a glass, in any shady situation.
S. peregrina (foreign). fl. yellow, four to five lines in diameter, five to eight-parted; stamens slightly shorter than the corolla; peduncles often fascicled, 2in. long. June l. much crenated. Madeira, 1771. (B. M. 218, under name of Disandra prostrata.)
