814 INDEX KEWENSIS. 
eats ire a Cypripediun n. Two o ther species of  Vellor o’'s— 
cothurnum and socco—are in the same ponitian ; a fourth, vittatum, has 
been identifie _ Mr. Jackson cites only the plates of these porn 
appearance of such names without any warning as ‘~ their soe 
is calculated to mislead the statistician who attempts to estimate 
the number of plants ina genus. In some cases a “quid?” or a 
cautionary aoe might well have been more frequently 
employed. The use of square brackets would have met the case. 
Another class of entry which is likely to mislead is exemplified 
under Cerber 
A cee ‘Kor Gawl. in Bot. Reg. t. 891 = Kopsia abesteg 
ruticosa, Roxb. Hort. Beng. 19; Fl. Ind. i. 691— 
fie ts it would seem that Roxburgh’s /ruticosa is a 1 ditornt 
plant from that of Gawler, and is to be retained as a species; but 
Gawler aéecribed his plant froth Roxburgh’s MSS., and cites for it 
the Hortus Bengalensis as cited above. There gala therefore be 
only one entry for this plant :— 
**fruticosa Roxb. Hort. Beng. 19 = Kopsia fruticosa.”’ 
In the case of nomina nuda, some such indication is even more 
monograph of sc emir are five names, ‘‘mihi nomine 
tantum note.” Eliminating one which Mr. Jackson has suc- 
ceeded in reducing, these pect thus :— 
‘i. atrosanguinea, Van Houtte Cat., 1851. 
AX. candida, E. G. Henderson Cat., "1851. 
repens, Van Houtte Cat., 1851. 
BE. Pcie Paxton Bot. Dict.” 
These four names seem to me of exactly similar value; yet a 
Jackson prints the first in italics, the second and fourth in Rom 
(as if duly ee ae ma accredited by botanists), "and omits the 
third altogether 
0 not 5 on what ‘eae ee are occasionally 
admitted. For example, Mr. Jackson i 
** Cypripedium Harrisianum x , Reichb. fi in ne Chron. (1869) 108”’: 
a cross between C. barbatum and C. villosum. But there are dozens 
of precisely similar hybrids which find no place: e.g., C. Ains- 
worthii X, Reichb. f. in Gard. Chron. ven xi. — Wh is one 
taken, while all the rest are left? In other these garden 
creations are more prominent, notably in Foun, where we have 
among others—
