Singapore : Kunstler 151 ; Deschamps. — Disteib. Native in warm 

 Africa and Mascarenia, a common plant ; runs wild as a weed in India 

 and South-East Asia. 



2. Nelsonia, E. Br. 



A diffuse herb. Leaves opposite, subequal. Flowers small, in dense 

 small spikes; bracts spiral or alternate (not opposite). Calyx small, 

 sub-4-lobed. Gorolla-\,\xhe slender ; limb 2-lipped. Stamens 2 ; anthers 

 2-celled, subincluded in the corolla-tube. Ovary 2-celled ; ovules about 

 8 in each, arranged vertically in two rows on the double placental line 

 in each cell. Capsule ovoid-conic, with 8 to 16 seeds in the basal half ; 

 retinacula 0. — Distrib. Species 1, in warm parts of Africa, India, 

 Australia, America. 



N.B.^This plant is often sorted amongst Sckophulaeiace.e ; nor does it differ 

 except by the arrangement of the ovules and seeds in one vertical line on the margin 

 of the carpellary leaf.

 long, 2-lipped ; one lip deeply 3-fid, the other shortly 2-fid. Corolla 

 •15 in. long, rose or white. Pistil glabrous ; style shortly 2-fid.

The innovations are often densely white-hairy ; there are also often long white 

 hairs at the base of the flower. The var. /3 vestita, of Fl. Br. Ind. IV. 395 (which has 

 large leaves, up to 8 to 10 in. long, on the branches), is frequent in Lower Burma, but 

 there is no example of it from the Malay Peninsula.
