4 Muhienbergia, Volume 
cient to carry details regarding month, and place of collection 
until winter when essentials could be supplied at the time the 
plants were named and inounted. Of course each gathering at 
any particular place was usually bundeled up by itself. 
“You can imagine how hard it has been to overcome all the 
faults which were gradually instilled into me. However, now 
plants have the label written for them at the spot where they 
are collected, giving number, details of locality, also name if 
known, and the same details are entered opposite a correspond- 
ing number in a note book. Each plant is pressed with the 
leaves arranged as orderly as possible. The driers are changed 
every morning, and when fleshy plants are in them, at evening 
as well. Every plant differing in any way froin the species to 
which it is supposed to belong is studied carefully with a view 
to seeing if it be something new or not. 
“There is a chance for a considerable number of new spe- 
cles and varieties here in ———_.” 
WHERE WAS RIBES BRACTEOSUM PUBLISHED? 
This species, so far as I can discover, has always been cited 
as published in Hooker’s Flora Boreali-Americana, 1: 233, the 
dates variously given as 1833 or 1834, until recently, when 
Piper in Cont. U. S. Nat. Herb. 11: 325, made it 1831. Tf any 
definite evidence has been discovered fixing 1831 as the date of 
issue for this particular part of the volume, I should be glad to 
have it explained in these pages. If the part in question was 
issued later than 1832, then Azbes bracteosum was first published 
in August, 1832, in Mem. Acad. St. Petersb. VI. 2: 138, in 
Bongard’s paper entitled ‘Observations sur la Vegetation de 
ile de Sitcha.—Ep. .
