SOME CRITICAL SPECIES OF ECHIUM. 385 
Smith has not attempted to determine all the specimens. Only seven 
species of Echium are enumerated in Fl. Gr. Prodr. i. pp. 124-126 (1806), 
and of the fourteen examples of that genus in the herbarium only seven have 
been named by Smith. Nine of the fourteen bear a printed label with 
“J, Sibthorp, M.D.,” indicating that they were actually collected by him. 
Three others are marked, apparently in a clerk’s hand, * Herb. Sibthorp. 
South of Europe. Qy.,” and the remaining two are from the Zante collec- 
tion mentioned above. From a copy of the * Prodromus" in the possession of 
the Linnean Society, it appears that at one time authentic Sibthorpian speci- 
mens of his Æ. hispidum and E. creticum, presented by Dr. Daubeny, existed 
in the Society’s general South European herbarium. Unfortunately, these 
were sold by auction on November 10th, 1863, being comprised in lot 82 
with Welwitsch’s Portuguese collection and Dr. Prior’s east Mediterranean 
plants. The lot only fetched 34 shillings, but the purchaser’s name is 
not known. The loss is peculiarly unlucky, as those two species are the 
very ones about which Smith went wrong. He appears to have taken 
the names of the three new species of the ‘ Flora Graeca’ (X. pustulatum, 
E. hispidum, and E. diffusum) from some list of Bauer's figures which he 
found among Sibthorp’s papers, but which does not seem to have been pre- 
served. Sundry rough lists exist among Sibthorp’s MSS., but they contain 
none of the above names. A list “intended to form the outline of the * Flora 
Greeea’” only includes three Lehia, viz., no. 164, Æ. italicum, no. 165, 
E. vulgare, and no. 166, Æ. creticum, without localities; and a list of 
Thracian plants mentions “ K. violaceum in campis Thraciv” and ** E. cre- 
ticum in campis circa Byzantium.” There is nothing in the lists to connect 
these names with any particular specimens. 
It seems that Bauer did not draw—or, at any rate, did not complete—the 
figures of the * Flora Groca from live plants. His originals exist at Oxford. 
They have been most faithfully reproduced by Sowerby in the published 
plates. There are also many sheets of Bauer’s pencil-sketches of the dif- 
ferent parts of the organs of the plants, perhaps done in the field, but at any 
rate from freshly-gathered specimens. Portions of several species belonging 
to different genera are found on the same sheet. These sketches are marked 
all over with numbers indicating the precise tints to be afterwards applied 
in the coloured pictures. The tints must have been very numerous, as the 
numbers run to upwards of 200. 
I have to thank Mr. Druce for much of the above information and for the 
facilities: afforded for the examination of the specimens enumerated and 
discussed below. 
(1.) ECHIUM VULGARE, L., labelled ** Herb. Sibth. South of Europe. Qy.” 
and not named by Smith. It is a large specimen with the upper half of the 
stem cut off, but I have little doubt that it is Æ. vulgare, which is quoted in
