NOTES AND OBSERVATIONS. 155 
Louisiana Av. Swamp May 8, 1889. Joor.’’ About one- 
half the fruits examined have an additional oil tube and 
rudimentary rib on one side next the commissure. I have 
also referred to this species another plant collected in the 
same locality by A. B. Langlois, May, 1880. This plant is 
more slender and has much longer peduncles.— Plate 48. 
LoBELIA CARDINALIS L. 
In July, 1897, I noticed this species flowering in the bog 
in the Garden, and it seemed to me, much earlier than I 
had seen it in flower in Kansas the year before. An ex- 
amination of the herbarium showed the following time of 
first flower, as nearly as could be ascertained from dried 
specimens and the dates of collection: Average of 7 plants 
east of the Mississippi river, Aug. 6; average of 5 Mis- 
souri plants, Aug. 24; average of 5 Kansas and Indian 
Territory plants, Sept. 5; average of 4 Texas plants, Sept. 
12; one Mexican specimen of L. splendens, Oct. 15. 
The western specimens form a transition from L. cardi- 
nalis of the East United States to LZ. splendens of the 
Southwest. The leaves are larger and narrower than the 
eastern form, more glabrous and less serrate, but I think it 
hardly deserves a varietal name. 
EUPHORBIA COROLLATA JOORII 0. var. 
Plant 10-14 cm. high, branching from the base, glabrous 
or pubescent; leaves ovate; involucres long pedicelled (10- 
25 mm.), appendages of the glands unequal in size, one or 
two shorter than the rest, sometimes narrower than the 
gland.— Plate 49. 
The collections of Dr. Joor in eastern Texas furnish 
this variety of this polymorphous species. The plants are 
from Milano, Texas. Most of them are glabrous or nearly 
so, but one, otherwise similar, is very pubescent with long 
hairs. 
EvrHorBIA EXSTIPULATA Engelm. 
This species, hitherto known only from Arizona, New 
Mexico, and western Texas, is represented in Wyoming by
