leaves lanceolate-spathulate, | to 2h 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, setae 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 H^lo, 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 bad been attacked by an insect, perhaps belongs 

 here : — 



HuiLLA. — Leaves radical, 1 to If 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 : — 



MossAMEDES. — -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 

 ^ 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 Sccevola. In the first edition of the Species Plantarum, 

 Linnaeus 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 Sccevola.
