sides with long appressed white hairs. Flowers about 15-18 in a 

 head about 50 mm. long, on pedicels about 2.5 mm. long, with 

 hairy linear bracts about 7 mm. ; flower about 17 mm. long and 

 only 5 broad ; calyx hairy, its tube about 8 mm. with five linear 

 lobes about 5 mm. Standard narrow, the sides folded upwards, 

 the expanded portions all deep magenta, the hidden whitish. 

 Wings long and narrow, surpassing keel by nearly 3 mm., ma- 

 genta, with the terminal portion broadly white. Keel pale ma- 

 genta with the margin whitish, apex deeply emarginate. One 

 free stamen. Peduncles densely white-hairy, the pubescence sub- 

 appressed and interwoven. Pod oblong, thick, pointed, about 20 

 mm. long, 6.5 broad, 5 high, curved upwards, sulcate (not very 

 deeply) only on dorsal side, more or less speckled with red, some- 

 times so much as to appear red except basally, quite glabrous, 

 2-celled by the intrusion of the dorsal suture, which touches but 

 does not unite with the ventral. Pods on pedicels about 3 mm. 

 long. 



Stony hills at Las Vegas, New Mexico,, growing in clumps, 

 May 18, 1 90 1 [T. D. A. and W. P. Cockerell). The fruiting 

 stems become at length depressed and buried in the soil. At the 

 same place grow Astralagus accumbens Sheld. and Potentilla sub- 

 viscosa Greene, these kindly identified for me by Dr. Rydberg. 

 The type of A. simulans is in herb. N. Y. Botanical Garden. 



Aragallus pinetorum Veganus var. nov. 



Similar to A. pinetorum Heller (1899), but only 1. 5-1.75 

 dm. high, and the flowers white, the keel with a pair of large 

 purple blotches within, showing through to the outside ; middle 

 of standard with a pair of faint purple patches. 



Heller's larger plant, with white unspotted flowers, occurs at 

 a much lower altitude, in the pine region. A. pinetorum Veganus 

 was very abundant in one locality only, an exposed treeless lime- 

 stone outcrop on the top of the Las Vegas Range, above the Sa- 

 pello Canyon at about 11,000 feet. It was discovered on June 

 26, 1 90 1, by 'Mr. Fabian Garcia, and on the following day I 

 spent some time on the spot studying the plants. The flowers 

 were observed to be visited by Bonibus and by Pyrameis cardui, 

 while the beetle Cantliaris Nuttallii was feeding on the leaves. The 

 type of A. p. Veganus is in the herb. N. Y. Botanical Garden ; I 

 am indebted to Dr. Rydberg for the recognition of its relation- 

 ship with A. pinetorum of Heller.
