624 LXXI, COMPOSITA. [ Sonchus 
leaves lanceolate-spathulate, 4 to 23 in. long, developed after the 
flowers ; flowers yellow, appearing at the beginning of spring in 
September and October; achenes narrow, truncate at both ends, about 
5-ribbed on each face; pappus white, setze smooth. On bushy slopes: 
near Halo on the left bank of the river Lucala ; fl. and fr. Oct, 1856. 
No. 3635. A herb; root thick, cylindrical, milky, many-headed ; 
young leaves lanceolate, subrepand, glaucous-green ; flowers lettuce- 
like, yellow, precocious, fugacious. In thickets at Halo, plentiful, 
after the burnings ; fl. and young fr. 8 June 1857. No. 3636. 
I have not seen O. Hoffman’s type; our specimens differ in having: 
fewer florets (13 or 14) in the capitula, and the inner involucral scales 
are 8 only. 
The following No., represented by a bad specimen, the young 
flowers of which had been attacked by an insect, perhaps belongs 
here :— 
Huitia.—Leaves radical, 1 to 1% in. long; scape branched, 3 in. 
high ; involucral scales 5. In pastures near Mumpulla, not found 
again subsequently ; fl. Oct. 1859. No. 3650. 
The following No. was referred to Sonchus by Welwitsch, but 
I have been unable to match it with any known species, and the 
specimen is too young to warrant its publication as new :— 
MossaAMEDES.—An annual milky herb, acaulescent ; leaves radical, 
rosulate, about 4 in. long, runcinate, denticulate with small prickle- 
pointed teeth ; inflorescence shorter than the leaves; capitula about 
4 in. long ; flowers yellow. About the mouth of the river Bero,. 
abundant ; young fl. July 1859. No. 3638.

I have not followed those botanists who substitute the name- 
Lobelia for Scevola. In the first edition of the Species Plantarum, 
Linnzus evidently did not consider this to be the typical form of 
the genus which he there called Lobelia ; he enumerated 25 species 
which are now considered to belong to 7 different genera, but 17 
of these species are still retained in the genus usually called Lobelia, 
and only one belongs to Scevola.
