culis sterilibus. Jnvolucri cylindrici sguame pluriseriales, scariose, sessiles,

ramis planiusculis apice capitellatis, in floribus masculis simplicissimus, apice 
incrassatus. Achenia fertilia, obovata, erostria, basi attenuata, dense seriacea, 
sterilia filiformia, nudiuscula, basi pilosa. Pappus omnium conformis, uniserialis,

SCH@NIA oppositifolia. Steetz in Lehm. Plant. Preiss. v. 1. p. 480. 
A lovely Swan-River annual, quite equal in beauty to the 
Lawrencella rosea and to the Rhodanthe Manglesii ot the same 
colony. Seeds were sent to us by Mr. Drummond, and our 
earliest plants blossomed in April 1846. The genus is founded 
by Steetz; and is nearly allied to Helichrysum, Helipterum, and 
still more to Pteropogon of De Candolle, from which it 1s said 
to differ by the inner scales of the involucre being appendaged 
and radiant, by the many-flowered capitula, and by the central 
florets being truly male. The generic name is given 1 com- 
pliment to Dr. Schoen, an excellent botanical artist. 
Descr. Root small, annual, branched. Stem erect, angled, 
downy, scaly, unbranched except in the terminal inflorescence. 
Leaves Opposite, connate at the base, nearly erect, linear-lanceo- 
late, obscurely three-nerved, acute, slightly downy and ciliate, 
sessile, upper ones acuminate, gradually passing into bracts. 
Flowers or capitula forming a broad handsome corymb : peduncles 
bracteated, bracts linear. Jnvolucre subcylindrical, imbricated 
with scariose, ovate, rusty-green scales, the imnermost row
