CALIFORNIA.— SUPPLEMENT. 
355 
Of this we have received one specimen, from the herbarium of the Hort. Soc. of London, under the name 
of Lasthenia glabrata. Indeed, Hologrjmne glahrata, Lasthenia glaberrima, Burrielia gracilis, and the 
present plant, are so similar in appearance, as to be often confused in herbaria and in gardens. The four 
may, however, at all times, and under all aspects, be readily distinguished by attending to the involucre and 
pappus. Burrielia Lasthenia have a paleaceous pappus — Hologymne and Baeria none; — on the other 
hand, in Burrielia and Baeria the leaflets of the involucre are distinct from each other, in Lasthenia and 
Hologymne they are united. ,

The specimens collected by Mr Douglas, and named by De Candolle H. puberulum, are younger, taller, 
less branched, and not so dark coloured when dry, as those from Chamisso’s and Beechey’s collection ; but 
they all appear to us to belong to the same species. De Candolle says the lower leaves are incised, but these 
we have not seen.

The Californian plant belongs to the var. jS. Besides those mentioned by De Candolle, Sclerocarpus exi- 
guus, Sm. in Rees’ Cycl. (De Cand. Prod. 5. p. 566), belongs to the present genus. It is a slender species, 
about four inches high ; leaves free from glands, half an inch long and half a line broad ; branches filiform, 
few, leafless, one-flowered, about an inch and a half long, with a few glandular hairs near the apex ; involucre 
of few leaves, covered with glandular hairs ; flowers of the ray from four to seven ; the ligula small and 
inconspicuous ; the florets of the disk are quite abortive. 
1. Hemizonia congesta. De Cand. Prod. b. p. 692. 
Our specimen is shrubby at the base, the leaves linear-lanceolate and quite entire. The first section of 
this genus is so closely allied to Madaria, both in character and habit, that we can point out no mark by 
which it may be readily distinguished, except that the achenia are obovate trigonous, the flat face being 
towards the disk ; while in Madaria, the achenia are laterally compressed. The stipes is remarkably 
curved up against the face of the achenium. 
2. H. multicaulis ; herbacea multicaulis, caulibus simpliciusculis vel apice corymbose 
ramosis pilis patentibus mollibus birsutis, foliis radicalibus lineari-lanceolatis serrulatis 
plurinerviis glabriusculis, caulinis villosiusculis longe linearibus, inferioribus oppositis 
serrulatis villosiusculis, superioribus alternis subintegerrimis, capitulis bracteatis 2-3-nis 
congestis, acheniis obovatis obtusis stipite rostelliformi inflexo. 
We cannot persuade ourselves that this is a mere form of the preceding, to which, however, it is very 
closely allied, except in habit. The root seems annual, or rather biennial, while H. congesta appears quite 
woody at the base. To the description given by De Candolle of H. luzulaefolia, this certainly approaches ; 
but there is no corymb, and we do not find palese over the whole receptacle.
