some of these varieties and forms will prob- 

 ably come to be taken as species or subspecies, 

 but most of them are clearly only deviations 

 from ordinary states of the species in color 

 or size of various organs, and the formal rec- 

 ognition of such things lumbers up nomen- 

 clature without aiiy useful result. 



Mr. Eehder recognizes two subgenera, 

 ChamcecerasuSj with four sections, and Peri- 

 clymenum, following the division accepted 

 by Linnseus, who united the four genera ac- 

 cepted by Tournefort in 1700, Gaprifolium, 

 Periclymenum, Xylosteum and Ghamwcerasus, 

 into the one genus Lonicera, of which it would 

 appear that the Lonicera Caprifolium is to be 

 taken as the type. Mr. Eehder remarks that 

 the two subgenera form two very well-defined 

 and nat^iral groups if based on the character 

 of the inflorescence, but he evidently does not 

 agree to recent propositions to recognize them 

 as genera. The genus Distegia of Eafinesque 

 is only given rank as a subsection, while 

 Nintooa of De CandoUe is given rank as a 

 section. Including the Mexican types, 21 

 North American species are recognized, no 

 new ones being described by Mr. Eehder from 

 within this territory in the present work; of 

 recently described North American species, 

 L. sororia of Professor Piper is reduced to L. 

 conjugialis Kellogg and L. ehractulata of Dr. 

 Eydberg is found to be inseparable from L. 

 Utahensis S. Watson. The species which has 

 long been called L. ciliata Muhl., is found to 

 have an older name in L. Canadensis Marsh. ; 

 L. villosa Michx. is reduced to a variety of 

 L. ccerulea L., following Torrey and Gray; L. 

 flavescens Dippel is made a variety of L. 

 involucrata (Eichards) Banks; L. Japonica 

 Thunb., naturalized in recent years in eastern 

 North America from New York southward, 

 is not uncommonly cultivated in the West 

 Indies; L. sempervirens receives a new variety 

 in var. hirsutula Eehder from North Carolina, 

 but an examination of two of the specimens 

 cited leads me to believe that this has no 

 serious claim to recognition under name; 

 L. subspicata H. and A. and L. interrupta 

 Benth., reduced to varieties of L. hispidula 

 by Dr. Gray, are restored by Mr. Eehder to 

 specific ranlv; L. dumosa Gray, which has 



recently been regarded as synonymous with 

 L. alhiflora T. & G., is maintained as a variety 

 of that species; Dr. Eydberg's recently pro- 

 posed L. glaucescens is accorded specific rank. 

 Only one American species known to the 

 writer is not referred to by Mr. Eehder, being 

 described by Dr. Small in his ' Flora of the 

 Southeastern United States,' issued in July, 

 1903, viz., Lonicera flavescens from Tennessee 

 and Kentucky; in naming this species, which 

 is related to L. Sullivantii and to L. fl,ava, Dr. 

 Small inadvertently overlooked the older L. 

 flavescens of Dippel, so that if the species 

 holds good it will have to receive another 

 name. 



Mr. Eehder's excellent paper is illustrated 

 by four plates of details of inflorescence and 

 morphology and by reproduced photographs of 

 little-known or rare Asiatic species taken from 

 sheets in the older herbaria of Europe, largely 

 from the collections at St. Petersburg. 



Mr. Eehder records 14 doubtful species at 

 the end of his monograph which he has been 

 unable to refer satisfactorily, and 24 hybrids, 

 most of which have originated in various 

 gardens, where the parent species have been 

 growing in proximity; none of the hybrids 

 is indicated as of origin in the wild condi- 

 tion; two fossil species of the genus are 

 known, both of them from European terranes.

Although the plan of this catalogue is ex- 

 cellent and its contents are good as far as they 

 go, it is improbable that any anatomist who 

 has access to Schwalbe's ' Jahresberichte 

 ueber Anatomic und Entwicklungsgeschichte ' 

 will find it very useful. For several genera- 

 tions past anatomists have been accustomed to 

 excellent year-books and a new catalogue will 

 naturally be compared to those already in 

 existence. The last volume of Schwalbe 

 (1901) is a large book containing over 1,300 

 pages, filled with numerous abstracts, giving 

 the titles to over 3,300 papers taken from over
