LASTHENIA, Cass. THE LASTHENIA. _ 
Lin. Syst. SYNGENESIA SUPERFLUA. 
GiNEKic Charictkr. — Flowers of the ray female, few, Small, tubular, i ciliated. Fruit compressed, pubescent. Pales of the pappus 5 — 10; 
and obliquely truncate. Receptacle conical, papillose. Involucral toothed at the apex, 
scales in one scries, combined into a 5, 8, or 15-toothed cup ; the teeth 1

Engraving. — Bot. Reg. 1823. I teeth. Pappus of 5 palete. 
Description, &c. — This very pretty plant was discovered by Douglas in California, and sent home by him 
in 1835. Since that time it has seeded so freely, that it has become common in the nurseries and seed-shops. 
It is generally planted with Nermphila imignis in flower-borders, and it may be treated like the other Califomian 
annuals, as described in p. 156, under the head of Leptosiphon. It is often confounded with Burrielia gracUit,

Specific Character. — Plant quite glabrous. Involucrum of 15 
teeth. Pappus wanting. Fruit mucronate.

Engravings.— Bot. Reg. t. 1780 ; Bot. Mag. t. 3730; and our /^. 
16, in Plate 31. 
Description, &c. — This species only differs from the preceding one in wanting the pappus, and in the 
manner in which the peduncles or footstalks are united to the involucre. In L. cali/ornica, the involucre is 
impressed at the base with a little cavity for the reception of the flower-stalk, and is thus cup-shaped ; while in 
L. glahrata, the involucre tapers gradually into the flower-stalk, like a goblet, or an old-fashioned wine-glass, 
without any perceptible point of union. Both species differ from the Burrielia — a plant often sold instead of 
them — in their involucres being always entire, and only cut into broad, spreading teeth at the apex, while the 
involucre of the Burrielia is divided into a double series of lanceolate scales. The seeds of L. glahrata may be 
purchased at any seed-shop, and they should be treated like those of L. cali/ornica. 
GENUS XIII. 
BURRIELIA, Dec. THE BURRIELIA. 
Lin. Syst. SYNGENESIA SUPERFLUA. 
Genhuc Chabactxiu — Head of many flowers. Flowers of the ray 
ligulate, obovate, female ; those of the disk tubular, hermaphrodite, 
and sometimes sterile by abortion. Involucrum campanulate, with 
oval acuminated scales. Receptacle apaleate. Acheniss subtetra- 
gonal ; those of the ray nearly compressed, furnished with a two or 
three-awned pappus ; those of the disk havins; a three or four-leaved 
pappus.

Syhokyiie.— Lasthenia Califomica, Mort. i Specific OaARACTEa. — Scales of involucrum eight ; flowers of the 
EHoaAViNO. — Bot. Mag. t. 37S8. I ray eight. 
Description, &o. — This genus, as already observed, is distinguished from Lasthenia by the different 
structure of the involucre, which is composed of several lanceolate scales in double series, whereas, the involucre 
of the Lasthenias is entire, and only cut into broad spreading teeth at the apex. The plant is a native of
