7, Allionia diffusa Heller, Minn. Bot, Stud. 2:33, 180s. 
This is a plant that is very difficult to understand and determine from her- 
barium material A considerable number of the specimens below referred here 
may be wrongly determined on this necount. The plant is distinguished from 
A. linearis chiefly by its diffuse habit, a character dificult to show in dried 
specimens,

&, Allionia glandulifera A. Nelson, Bot. Gaz. 34: 364. 1902. 
Various authorities have stated that this is the same as A. diffusa, Tt cer- 
tninly resembles that species very closely, but I do not believe that it can he 
the sume. 1. glandulifera is a larger, rather more branched plant of a much 
brighter green color. It also seems to be more pubescent and glandular.

9, Allionia vaseyi Standley, sp. nov. 
Stems low, about 20 em. high, sprending, much branched, the branching 
dichotomous, glabrous below or minutely roughened, more or less soft-pubescent 
above near the ends of the branches; leaf blades linear, sessile, thick and 
fleshy, slightly or somewhat pilose on the lower surfaces; involueres axillary 
or a few clustered at the ends of the branches, short-pediceled, the pedicels 
being shorter than the involucres, about 10 mim, wide and 7 lim. high, the lobes 
elliptical or even lanceolate, acute, covered by rather long, soft, matted hairs;
