oblong, 4 lines longer than keel, expanded at base like 4. Beckwithit, 
sides reflexed 20° or less, groove very shallow and acute, scarcely 
narrower at base, not enlarged or narrowed on the outside toward 
the base; banner acutely notched at apex, 34 line deep; wings 
obliquely obovate or lanceolate, ascending 45° so as to expose the 
bottom of keel, concave to keel, entire or obscurely toothed at 
rounded apex; keel incurved 100° or more, blunt, tipped with yel- 
low. Schell Creek Mountains, Nevada, July, 1891. 
ASTRAGALUS KENTROPHYTA Gray. It is hard to believe that a 
subalpine plant in the Wasatch can be the same as one growing on 
the driest slopes of valleys in the arid regions, but so far I can see 
no distinguishing characters. The floral characters of the arid plant 
are these: calyx bent like Hedeoma; banner arched less than 90° 
abruptly and with a hump below the bend also, cucullate, sides very 
concave and little reflexed; sulcus very shallow; banner contracted 
about a line below the tip, so that the general outline is oblong, tip 
abruptly reflexed or not at all, deeply notched, a little broader at tip 
than below, finely striate veined with purple; wings connivent, ob- 
long-ovate, obtuse or barely acute, 114 lines longer than keel, as- 
cending; keel purple tipped, sharp, and much incurved. Very dry 
knolls in valleys of Eastern Nevada, fruit in July. 
In my last ‘ Notes’’ in Zox I inadvertently transposed the terms 
dorsal and ventral in describing my species of Astragalus. 
CERCOCARPUS LEDIFOLIUs Nutt. In a former communication in 
ZoE I gave some general details of the relation of the type to the 
variety zutricatus Jones. Having now examined minutely all my 
material from all sources and also that in the Shaw Botanic Gardens 
(the Engelmann collection), my conclusions are that there is but one 
good variety of C. dedifolius and that one is the var. iztricatus, which 
does not deserve higher rank. C parvtfolius Nutt. var. breviflorus 
Jones. I reduce from the C, breviflorus Gray, Pl. Wright 2 p. 54. 
It is ciearly a form of the more robust species. C. fothergilloides 
HBK. is quite variable, and some forms are hard to separate from 
C. parvifolius. 1 studied this latter carefully in the Sierra Mojada 
in May, 1892 (Mexico). : 
The following are some notes on C. ledifolius and its variety. The 
species sheds its leaves late in the second season. 
July 2, Muncy, Nev. Leaves lanceolate to linear, Margins revolute, 
nearly glabrous, bark dark gray.
