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.

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 Capri foliaceous 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. oxy coccus, edule and opuloides are shewn to be 

 mere forms of the European V. opulus. 



Rubiacese are made to contain both Galiacese and Cincho- 

 nacese ; 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. Loganiese are also included in Rubiacese, 

 we think injudiciously, and a remarkable new genus, called 

 Ccelostylis, is added, from Florida and Texas.
