hin’s 2. montanus gramineofolio. R. parnassifolius was Tournefort’s 
RR. montanus graminis parnassifolic. R. bullatus is Bauhin’s R. latifol- 
tus bullatus. Unfortunately for Dr. L.’s illustration he never estab- 
lished a #. palustris. There was, to be sure, Bauhin’s “2. palustris 
apitfolio levis,” but for once he ignored both the swamp and the 
smooth parsley leaf, and dubbed it &. Sce/eratus. Thus we might go 
through the whole list of the Linnzean ranunculuses. Ophioglossotdes 
is from Villars, Ficaria from Haller, Zora from Crantz, Creficus from 
Bauhin, cassudicus from Breyne, aconitifolius from Bauhin, rutefolius 
from Bauhin, and so on of many others, a large number being Bau- 
hin’s names. 
In the reorganization of systematic botany, Linnzeus was a collator 
and condenser, rather than a creator, and the fact that, as far as pos- 
sible, he preserved the work of his predecessors, and did all honor to 
their labors, justifies the high estimation of his personal character so 
generally entertained—TuHomas MEEHAN, Germantown, Philadelphia. 
A day-blooming Cereus grandiflorus.—Our Cereus grandiflorus has, 
on three occasions and with five different blossoms, made a fatal and 
in no instance entirely successful effort to expand during the day. In 
each case the abortive attempt was caused by a sudden marked lower- 
ing of temperature when the bud was almost ready to open, thus retard- 
ing the growth. 
In the first instance, a year ago, the flower partly opened about 
8:00 A. M. on the second day after it had to all appearances planned to 
expand had external conditions proved favorable. It soon drooped, 
however, as the sun’s rays fell upon it. 
This year the cold wave early in July, with mercury at 44° at af: Mey 
and but little higher at mid-day, caught two fine buds in a similar 
manner. Again expansion was retarded at least one, and, I am in- 
clined to think, two days and several odd hours. They opened suffi- 
ciently to show the interior at 10:00 A. M. and 11:00 A. M. respectively, 
and like their abnormal predecessor soon drooped in the sunshine 
(the plant stands on a south porch), and did not revive with the ap- 
proach of twilight as a friend fondly hoped. : 
Again, Aug. 1st, two other buds similarly retarded behaved in the 
same way. The day was cool and cloudy. At 9:00 a. M. the sepals of 
one had loosened at the tip. From 9:30 to nearly 10:00 o’clock the 
phenomena that attend the normal opening of this beautiful flower 
were present. At 10:00 a. M. the maximum was seemingly reached, 
outer sepals, instead of bending back almost to the tube, opened 24 
nearly a right angle with it; the stigma, as in all previous abortive ¢h
