128 AMERICAN MIDLAND NATURALIST 
Pale green with stout stems ascending from a woody rootstock, 
geniculate, with white, appressed hairs, 3dm. high. Leaflets 11-19, 
oblong or narrower, 10-25 mm. long, 3-7 mm. wide, short-petiolu- 
late, with white, dense, strigose hairs. Flowers ascending, in a 
large, dense cylindrical head, 3-4 cm. high and 2 cm. broad. Calyx 
densely white-strigose without scattered black hairs, with green, 
later whitish, white-strigose margined teeth as long as the tube. 
Floral bracts narrow, nearly as long as the calyx tube. Corolla 
about 1.5 cm. long, white or whitish. Pods not seen. 
This beautiful plant differs from A. nztidus Dougl. by its large 
heads and leaflets and its longer calyx teeth, and from this and 4. 
sulphurescens Rydb., a native of Colorado, by its white-strigose calyx 
without the admixture of more or less scattered black hairs, and by 
its large, white or whitish corolla. In addition, these two allies are 
as a rule glabrate, or else have only a scanty pubescence. 
The handsomely prepared type specimen was collected in dry 
soil at McHugh near Detroit, Minn., on June 16, 1911, by Rev. 
Father Z. L. Chandonnet, who works ardently and enthusiastically 
in the botanical field whenever season and sacerdotal duties permit. 
It was simply a matter of course that this species should be named 
in his honor. 
Meibomia grandiflora Chandonnetii var. nov. 
Folia circum basem pedunculi haud, sed in parte quadam inferiore 
caulis accumulata. Insuper folium solum basem pedunculi ornat, 
saepeque folium alterum semel vel interdum bis subtus additur. 
Saepe demum folium solum semel (vel bis) infra parten foliorum 
accumulatam patefieri solet. 
Leaves not clustered at the base of the peduncle, but further 
down on the stem. In addition to these there is one single leaf at 
the base of the peduncle, and often one or sometimes two single 
leaves beneath this. Lastly, there are often one or two single leaves 
on the stem below the clustered part. One plant had only single 
leaves and no cluster at all. 
This variety, also named for Rev. Father Z. L. Chandonnet, was 
collected by him at Beaulieu, Mahnomen County, Minn., on July 
27, 1911, and at other times. In submitting it to me he furnished 
valuable data regarding the plant. It is the frequent form there. 
I have also a specimen rightly belonging here and collected by Mr. 
Chas. C. Deam in Wells County, Indiana, with a single leaf 0-5 dm. 
above the clustered leaves, being his number 2325.
