and Decaisne of Paris I have now had the opportunity of 
examining and comparing fragments of Lamarck’s original 
J. pallescens and Michanx’s J. acwminatus. The former’s 
name refers, as Prof. Roeper informs me, to two poor (more 
suo) specimens collected by Commerson near Buenos-Ayres ; 
the heads are apparently 5-flowered; the flowers, not yet 
re are similar to those of our plant, but are 6-androus and 
pedice marck gives North as well as South America 
as the habita t of his plant, but adds that his specimens are 
those above noticed; his reference to North America is evi- 
dently based on quotations from Pluk. Alm. t. 92, f. 9, and 
something like J. tenuis. Meyer was undoubtedly misled by 
these references to North American localities to substitute 
Lamarck’s to Michaux’s name. La Harpe, p- 136, suggests, 
probably with more justice, that Commerson’ 8 plant is an im- 
mature J. Dombeyanus. Michaux’s specimen, collected in 
South Carolina, is a rather small-flowered form of var. legiti- 
mus, such as often occur south-eastward (comp. Hb. norm. 
58), with only 5 flowers in a head (Michaux says 3 flowers), 
the (unripe) capsule being about as long as vase a als =.

can most positively assert that it is a scanty-flowered form ‘of 
what I have called var. legitimus, with the outer sepals very 
slightly exceeding the inner ones, and with a not fully ripe 
capsule about the apt an of the inner sepals. Meyer's 
aradoxus is more difficult to identify, because the original 
specimen does not siting in his herbarium ; he had examined 
it, as a memorandum indicates, in Hb. Lehmann, to whom it 
was given by Willdenow under the name of J. polycephalus, 
and preserved only a drawing of it and a rough sketch of 
some details. There are, however, in the sheet superscribed
