Cossignia
(named after M. Cossigny, a French naturalist, once resident at Pondicherry, who presented Commerson with an herbarium of the plants of Coromandel). ORD. Sapindaceoe. An ornamental stove shrub, with impari-pinnate leaves. A compost of two parts loam, and one each of peat and sand, suits the Cossignia. Through drainage, and a liberal supply of water, are essential points in its culture. "This plant may be increased by cuttings of the ripe wood, inserted in sand, and plunged in a strong moist heat; we have not, however, found them root very freely" (B. S. Williams).
