ripening seeds in abundance. According to Dr. Royle it is 
found in Mussooree and elsewhere in the Himalayas during 
the rainy season. It is a herbaceous plant, with leaves like 
those of Ginger. Its flowers are pale buff, and appear in ter- 
minal spikes; the bracts and calyx are purple. It is not a 
plant of much beauty.

This does not appear to be different from O. unicorne. 
A Flora of North America, containing abridged descriptions of all the known 
indigenous and naturalised plants growing north of Mexico, arranged ac- 
cording to the Natural System. By John Torrey and Asa Gray. Vol. II. 
Part I. 8vo. New York, May 1841. London, Wiley & Putnam. 
We have on former occasions (1839 misc. p. 42. 1840 
misc. p. '79) expressed a high opinion of this most useful work, 
recommending it strongly to all Botanists, as by far the most 
complete and exact account of North American plants. It is 
now therefore only necessary to state that the part lately pub- 
lished fully maintains the reputation of its predecessors. We 
shall confine ourselves to an enumeration of what it contains. 
The part begins with the Caprifoliaceous order; and of 
course the North American Honeysuckles are critically exa- 
mined ; altogether 15 species are mentioned, among which are 
some new ones chiefly from Oregon and the Arkansas. Loni- 
cera (Caprifolium) albiflora, has small glaucous leaves and 
white flowers ; L. californica is a new species from Monterey, 
with pale yellow flowers; Viburnum nitidum, cassinoides, py- 
rifolium and squamatum, are all regarded as forms of V. 
nudum ; V. oxycoccus, edule and opuloides are shewn to be 
mere forms of the European V. opulus. 
Rubiacee are made to contain both Galiacew and Cincho- 
nacez ; to the latter of which the Southern States have fur- 
nished some additions in the form of Spermacoceous plants, 
and several of the higher forms of the order, such as Chiococca 
racemosa, Psychotria lanceolata, Morinda Royoc, &c. ; most 
of which have apparently reached the main land from the 
West India Islands. Loganiew are also included in Rubiacez, 
we think injudiciously, and a remarkable new genus, called 
Ceelostylis, is added, from Florida and Texas.
