des : the two genera have also nearly the same geographical range. The sterile 

 rays chiefly distinguish it from Aster §1 Orthomeris (species of Calimeris of 

 authors) ; to which Aster nemoralis, Ait. belongs. 



1. G. hyssopifolia (Nee.s) : nearly glabrous, minutely scabrous ; the co- 

 rymbose branches numerous and crowded; leaves lanceolate-linear, acute, 

 narrowed at the base, punctate, 3-nerved ; tliose of the branches small, sub- 

 ulate-linenr ; involucre about half the length of the disk ; the scales acutish ; 

 the exterior ovate-lanceolate, rather fleshy ; the interior larger, linear-ohlong, 

 with membranaceous margins ; rays 5-10, longer than the disk. — Nees, AsL

 —Stem 1-2 feet high, strict. Leaves 1—3 inches long, s[)reading, 1 -nerved, 

 and often with two less distinct lateral nerves. Rays while, tinged wiih pur- 

 ple. — This is a very uncommon plant, if indeed it be a native of the United 

 States. We have never met with an indigenous specimen, unless that in 

 Elliott's herbarium, communicated by Muhlenberg, should prove to be so. 

 Nees, however, professes to have seen not only spontaneous specimens of his 

 G. linifolia (which appears to differ from G. hyssopifolia merely in its short 

 rays), but even to have met with New Jersey specimens of G. dracuncu- 

 loides. His G. leptophylla, an impunctaie species of unknown origin, is 

 also conjectured to be a native of North America. The species of Galatella 

 are still in much confusion.

Heads many-flowered ; the ray-flowers neutral, numerous, in a single se- 

 ries; those of the disk tubular, perfect. Scales of the hemispherical invo- 

 lucre imbricated in several series, lanceolate or linear, with somewhat spread- 

 ing tips ; the exterior shorter. Receptacle flat, obscurely alveolate, some- 

 times with linear chaflT scattered among the flowers. Rays linear, elongated ; 

 the corolla of the disk cylindraceous, with 5 short (somewhat hairy) teeth. 

 Anthers tipped with a filiform-cuspidate appendage. Branches of the .style 

 linear, bordered with conspicuous sligmatic lines, tipped with a dense peni- 

 cillate tuft of rather rigid bristles. Achenia of the ray none, or a mere rudi- 

 ment; of the disk cuneiform or turbinate, silky or villous. Pappus simple, 

 of numerous rather rigid scabrous unequal bristles ; thatof the ray obsolete, or of 

 few short and unequal bristles. — Perennial herbs or sufTrutescent plants (na- 

 tives of California), clothed with a soft and white, at length somewhat decidu- 

 ous wool ; the branches terminated by rather large solitary heads. Leaves 

 numerous, linear-lanceolate or oblanceolate, mucronulate, closely scs.sile ; the 

 radical and lowermost tapering into a petiole, serrate or toothed towards the 

 apex. Rays violet-purple; the disk yellow. Pappus turning reddish-brown 

 or purplish. 



To this interesting genus (founded upon a Califomian plant collected by Douglas) 

 we had refeiTcd, from their description, the Aster? filaginifolius and A."? tomen- 

 tellus of Hooker &c A rnott in Beechey's Voyage. Some time afterwards, findin" 

 two species in the collection of Mr. ]Suttall, upon which he had established a new
