ning from the lower part or the middle of stem and branches. Var. y. has smaller 
leaves (about 4 lines wide, lamina as long as the petiole), subsolitary pedicels, 2 or 
3 styles, 4-5-locular ovarium and a suborbicular fruit about 4 lines long.

papulose-hirsute, from the middle floriferous ; leaves 2-1 inch long, 9-3 
lines wide, oblong or lanceolate, subacute, attenuated in the petiole, papu- 
lose, when dry subleprose ; flowers axillary, flowering pedicels 13-5 
lines, in fruit 6 12 lines long, terminal ones sometimes aggregate, sub- 
hirsute; lobes of calyx ovate, 1-1} lin. long ; stamens very numerous ; 
styles 3-5 ; fruit suborbicular, 10-16 lines long, deeply emarginate at

flowers, and the large fruit. 
7. T. chenopodioides (E & Z.! 2118); papulose, stem decumbent, 
slender, branched from the base ; leaves subspathulate-elliptic or lan-

subsessile, at length very short pedicellate, disposed in an interrupted 
leafy spike ; pedicels dense papulose ; calyx lobes yellowish, broad tri- 
angular-ovate, acutish, 1 line long, tube 4-costate ; stamens 15-20 ; 
styles 3-5, very long; fruit (probably) winged. 
Has. near Saldanhabay, Z. § Z./ (Herd. Sd.) 
It resembles small specimens of Chenopodium polyspermum. From 7. portulacot- 
des and galenioides it differs by the slender stem, very minute, aggregate flowers, 
short, only 2-4 lines long, fruit-bearing pedicels and very long styles. 
8. T. galenioides (Fenzl.) ; papulose-hirsute, diffuse, branched ; leaves
