BOTANICAL GLEANINGS IN MICHIGAN. 205 
Small plants with simple stems usually growing in pure sand, 
by some authors have been confused with OE. Oakesiana and 
with OE. parviflora var. canescens. Common throughout the 
state. Keweenaw Co., No. 721, Sept. 1, 1889; Woodville, No. 
5957, Aug. 4, 1921; Slocum’s Island, No. 5986, Aug. 31, 1921. 
Var. rubricaulis (Farwell) n. comb. GZ’. muricata var. ru- 
bricaulis Farwell, Papers, Mich. Acad. Sci. Arts and Lets. 
I (1923) 95, 96. Appears to be hybrid between CZ. biennis and 
G@. muricata with the leafless spikes of the former and the 
muricate pubescence of the latter. Stems purplish-red, leaves 
more or less suffused with red. 
Anethum graveolens, L. Dill. Roadsides, associated with 
Hibiscus Trionum. Erie, No. 6642, July 11. 
Primula Mistassinica Mx. Similar to P. farinosa but easily 
distinguished by its thin, veiny leaves, with little or no trace 
of mealiness, its longer pedicles and corolla tubes. Sandstone 
ledges at Grand Ledge, No. 6563, June 10, 1923. 
Fraxinus Michauxii, Britton. One of the segregates of F. 
Pennsylvanica Marsh. Near Monroe, No. 6703, August 22. 
Asclepias Sullivantii, Engelm. Similar to A. Syriaca but 
smooth throughout, its flower buds twice as large and the 
flowers larger, usually darker purple but varying to almost 
white. Occasionally, the upper part of the stem is fasciated 
and bears the leaves in whorls of four. Erie, No. 6639, July

Asclepias verticillata, L. This species usually is said to be 
from a fibrous root. It is from a slender, horizontal rhizome, 
1.5 mm thick or less, from 4 to 19 cm under the surface; it is 
not shown on plants that have been pulled up; in order to ob- 
tain it, it must be dug up. Stems arise singly at one or more 
nodes of the rhizome; the aerial portion of the stem dies down 
to the surface of the earth at the close of each floral season 
and the subterranean part sends up one or more branches 
from one or more of its nodes at the beginning of the following 
season; also from the same nodes, fasciles of fibrous roots of 
about the same size as the rhizome arise. I have seen as many 
as 25 branches arising in this way from the original stem 
which had become 8 mm thick at the point of contact with the
