OF ORNAMENTAIi ANNUALS. 189 
CaKfornia, and its seeds were sent home by Douglas with those of the Lasthenias, with which it is generally 
confounded, the flowers closely resembling those of that genus. Seeds of the Burrielia are seldom to be prociired 
under their proper name ; but when they are, they should be treated like those of the Lasthenias ; and all the 
three kinds of plants, like all the Califomian annuals, will come into flower at any time during the spring, 
summer, or autumn, about six weeks after sowing. 
GENUS XIV. 
HELENIUM, Lin. THE HELENIUM. 
Lin. Syat. SYNGENESIA SUPERFLUA. 
Gemeric Chaiucter.— Flowers of the ray in one series, ligulate, 
rarely tubular; those of the disk hermaphrodite, tubular, 4 or 5-toothed. 
Receptacle convex, globose or oblong, naked. luvolucral scales in two 
series ; outer scales many, defiexed or spreading ; inner ones fewer 
and shorter, similar to the pnlese of the receptacle. Fruit obovate, 
villous. PaleiB of pappus 5 or 6, membranous. 
■HELENIUM QUADRIDENTATUM, Lab. THE POUR-TOOTHED HELENIUM. 
Sfkcific Chik4cteb. Plant nearly glabrous. Stem erect, branched 
at the apex. Leaves decurrcnt, oblong-linear; lower ones pinnatifid, 
upper ones quite entire. Involucrum very short. 
Synonymes. — Rudbeckia alata, Jacq, ; Helenium Millerii, Schult. ;

Enoravino. — Bot. Reg. t. S98, 
Description, &c. — A very handsome plant with a bright orange-coloured ray, and elevated disk like that of 
a Rudbeckia. The stems are curiously shaped, and winged, and the leaves stem-clasping. The name of 
Helenium was originally applied to the Inula Helenium, the elecampane, which, in allusion to its cosmetic 
properties, was dedicated to Helen. The present plant is a native of Louisiana, from which country it was 
brought in 1790 by the Abbe Pourret. It is a hardy annual, which only requires sowing in March or April to 
flower in August or September. Though the stems are tolerably strong, yet, as the root is fibrous and slender, 
it is advisable to tie it up, if the situation in which it grows is at all exposed to the wind.

lip large, toothed at apex ; inner lip divided into two linear segments.

nished with oval, acuminated paleae Which clasp the flowers. Fruit 
almost cylindrical. Paleae of pappus in one series, pinnate or plumose.

Description, &c. — This showy annual is a native of Mexico, from which country it was sent to Madrid, 
where Cavanilles supposing it to resemble the Galimogea quinque radiata of Euiz and Pavon, a Peruvian plant, 
gave it the name of Galinsogea trilobata. It has since been found to differ in the form of the florets of the ray, 
the shape of the receptacle, the colour of the flowers, &c., and it is now placed in another genus under the name 
of Sogalgina, which is an anagram of Galinsogea. The heads of flowers of the true Galinsogeas are small with a
