Plante Europee Enumeratio Systematica et Synonymica 
Plantarum Phanerogamicarum in Europa sponte Crescentium 
vel mere Inguilinarum. XK. Richter. (Tom. i. 8vo., pp. 378. 
Leipzig, 1890.) 
This is the first volume of a catalogue of native and natural- 
ized plants of Europe. It includes the Gymnosperms and 
Monocotyledons arranged after Engler and Prantl’s “ Natiirliche 
Pflanzenfamilien,’ and enumerates 1839 species, 840 subspecies, 
122 hybrids and 52 doubtful species. The geographical distribu- 
tion is given, and in cases where the plant extends beyond Europe 
this is indicated, although not very comprehensively, so far as 
North America is concerned. There isa very full citation of 
synonyms, as illustrated by the following specimen: ~ 
CALYPSO, SALISB. 
C. BULBOSA [L.] Rb. f. Icon. xiii. p. 158 (1851). 
Syn.: C. doreale, Salisb. and Hook Parad. Lond. p. 89 (1806). 
Cymbidium boreale, Sw. Nov. Act. Ups., p. 76 (1799). 
Cypripedium bulbosum, L. Sp. Pl. p. 945 (1753). 
Limnoclorum boreal, Willd., Sp. Pl.iv. p. 122 (1805). 
_ Norna borealis, Whib. Fl. Suec. p. 561 (1824-1826). 
Orchidium boreale, Sv. Bot. viii. p. 518 (1819). 
Europa borealis. (Regio arctica.) 
In cases where the species has originally been described in a 
different genus than the one accepted, the author is cited in 
brackets, as in the foregoing example. In cases where it has 
originally been described as a species, but regarded by Herr 
Richter as a subspecies, or vce versa, the only original author is 
given in parentheses, thus: 
SPARGANIUM ERECTUM, L. Sp. Pl. 971 (1753). 
b) NEGLECTUM (Beeby), Journ. Bot. xxiii. p. 26 (1885.) 
In cases where both these circumstances have obtained, both 
parentheses and brackets are used thus: 
EPIPACTIS LATIFOLIA [(L.)], All. Fl. Ped. ii. 151 (1785). 
Serapias Helleborine, var. latifolia, L. Sp. Pl. 949 (1753). 
Original specific or varietal names are rigorously maintained, 
the only apparent exception being where they are identical with 
the generic appellation. As so large a number of European 
‘plants are identical with North American (although the actual
