80 - Mr. Brown’s Observations on the 
Since my attention has been again turned to the subject, I have 
endeavoured to collect all that has been observed on the nerves 
or vessels of the corolla of Composite, a brief account of which 
may be not altogether without interest. 
The earliest notice I have been able to find is-contained in a 
passage (in page 170) of Grew's Anatomy of Plants, where, in 
speaking of syngenesious flosculi, he says, **they are frequently 
ridged, or as it were hem'd like the edge of a band." And his 
figure of a magnified floret of the common Marigold, in tab. 61, 
gives a tolerable idea of the marginal vessels of its laciniæ. Grew 
however takes no notice of the trunks from which these branches 
arise, either in his text or plates. à 
Van Berkhey, in his Dissertation on Composite, published at 
Leyden in 1760, though he makes no mention of the nerves of 
the corolla in his text, yet in all the magnified figures he has 
given both of ligulate and tubular florets, correctly represents the 
trunks of the primary vessels, without however noticing their ra- 
mification in the laciniæ. I am anticipated therefore by this au- 
thor’s figures exactly in the same degree as by the passage con- 
tained in M. Cassini’s second memoir. 
The accurate Schmidel, in the few Composite which occur in his 
Icones, has correctly represented the trunks of the primary ves- 
sels, but has equally omitted their ramifications. 
In the Analysis Florum of Batsch, a work published in 1790, the 
object of which was to give an idea of the structure of the natu- 
ral families of plants, by a minute description and magnified 
figures of one or more species selected from each, Coreopsis tripte- - 
ris occurs ; and although the vessels of its tubular floret are very 
indistinctly figured, yet both their trunks and branches are cor- 
rectly described. The same author however, who in 1802 pub- 
lished
