WoRKS CALLED HERBARIUS 305 
LV. AGGREGATOR PRACTICUS 
Of all much-vexed subjects in early botany, the next work to 
be mentioned, the work which calls itself the Aggregator Prac- 
ticus, has perhaps given rise to the largest number of uncertain- 
ties. Contenting ourselves at present with conclusions, we may 
say it is an alphabetical series of 150 uniform plant-chapters with 
figures, from Absinthium to Usnea, each plant being allowed two 
pages, the text restricted to the medical uses and chiefly extracted 
from Plateario, Matteo Silvatico and Serapion ; followed by 96 
other chapters without figures, of which 60 relate to plant 
products, gums, etc. It is a work cast in the Salernitan mold, 
may have existed as a Latin MS. as early as 1350, and is now 
known to us as a small quarto volume, either in Latin, German 
or Dutch. Its author and his nativity are unknown ; but whether 
written in Italy or in Germany as variously claimed, it is certainly 
a late outcome of the Salernitan school, and Meyer censures it for 
making little if any advance upon the Pandects of Matthaeus 
Sylvaticus. Long known as /Zerbarius, in its various editions it forms 
the series treated separately by Pritzel, p. 349, under that name — 
Herbarius, *—a name also used for the Ortus Sanitatis, for the

confusion because too general. Other works or authors liable to confusion with it in- 
clude the following :

Pot now known to be extant; Sprengel thought it a compila 
twelfth century from Arabic writers and from Pliny; I have entered it in the tabular 
view, p. 97, as probably a Salernitan herbal. 
; Aggregator Paduanus, in Latin, written 1355 (Schrank) by Jacobus de Don-
