O. rupestre M. B.—a reduction first made by Lehmann (Asperifolia, 
ii. 870), where the name is misprinted tenuifolium. It will be clear, 
however, from the appended bibliography that Willdenow’s name 
t 
must be maintained, if the two plants are, as is generally agreed, 
ynonymous. Bentham (J ig quoting Willdenow’s name, adds 
‘* excl. ex Le n. To ” +. T can find no definite exclusion in 
Lehmann of Tournefort’s synonym, although it is true he does not 
specifically cite it. Willdenow, however, took his name tenuiflora 
from Tournefort’s descriptive phreag “Symphytum —— echii 
folio, “ae albo oo”. n specimen from Tournefort in 
the National Herbarium, so nam oe by him, agree with the

Tournefort’s specimens in his herbarium ; Lehmann (i.c.) speaks of

HISTORY OF PLANT CLASSIFICATION. 
Tuer is - present on view in the public eres of the Depart- 
ment of Botany at the Natural History Museum an interesting 
exhibition i books and portraits illustrating “« the chief epochs in 
the development of a natural system of plant classification; that 
is to say, a system which shows the actual relationship of plants as 
contrasted with an walpige system which i is based on the differ- 
—. presented by one set of organs.” To accompany the exhibi- 
a Guide has been pare = Dr. Rendle, from whose preface 
ay acai sentence is quoted; it consists of the labels connected 
with the exhibition expanded into a useful little account of the 
principal stages in the development of the subject, with short bio- 
graphical notices of the writers of the books shown. 
e authors whose works are selected for exhibition include 
Otto Brunfels (ce. 1488-1534) whose a barium contains woodcut 
sa hardly if at all inferior to the much-admired ones in 
Fuchs’s New Kreiiterbuch of a few vile aii William Turner 
(c. 1512-1568) the illustrations of whose Herbal are greatly inferior 
to those just mentioned; John Gerard (1545-1612) who, following
