“Tinctoru florts tertium genus, das dritt Schartenblumen ge- 
schiecht.’’ Gesner also cites this, but as “7Zinctorius flos luteus, 
Tragi.” Jean Bauhin deemed these as probably synonyms of his 
“Conyza media Monspeliensis, quibusdam Asteris Attici genus 
folio glabro rigido ;” called by Caesalpino “ Asteris Attici altera;” 
by Lobel, Aster montanus; by Caspar Bauhin, Aster 5. Jean 
Bauhin notes of it that “ Frater Casp. Bauhinus misit collectam 
Basiliensibus montibus, nomine Asteris conyzoides Gesneri.” This 
plant appears in Linnaeus as /uula spiraeifolia. 
4. Chrysanthemum segetum L.,=Bock’s Tinctorius flos 4 ; Cas- 
par Bauhin (Pinar, p. 134) styled it Chrysanthemum folus matri- 
cariae, etc. 
Such are the plants Aster Amellus L., Erigeron acre L., /nula 
Spiracifolia L., and Chrysanthemum segetum 1,., which Bock classed 
together ; the first and last, at least, used in a rude way for dyeing, 
and all, if not first-class dye-stuffs, at least looking as if they ought 
tobe so. Singularly enough, Bock, who was a law unto himself, 
is at variance from his chief co-workers in the use of this term 
“ Flos tinctorius,’ which in the usage of many others meant the 
Genista tinctoria * of modern botany, a plant much more important 
to dyers than those chosen for the title by Bock. 
When Bock was classing together his dyer’s plants as “ Zinc- 
torius flos,” it would have seemed natural had he included among 
them the Anthemis tinctoria of modern botany ; but for that he used 
the old name Buphthalmum, in which practice he was followed 
by Matthioli and Clusius and at times by Gesner. Perhaps Bock 
varied at times, however, and at the time of writing of his Tinctorius 
flos primus intended to include Anthemis tinctoria under it, under 
his name of Chamaemelum tertium. : 
Finally, Bock is cited by Jean Bauhin, 1: 1044, 4S using the 
Phrase Aster Atticus flore medio luteo as a name for what Jean 
* Genista tinctoria had also the right of authority to the name 2 — ay as
