bracts is less than half as long as the width of the wing. It differs 

 from A. occidentalis Torr. in its narrower and sharply toothed 

 wing. 



Atriplex Garretti sp. nov. 



A low shrub, with straw-colored branches; leaves short- 

 petioled, oval, 2-3 cm. long, grayish, scurfy on both sides, acute 

 at the base, abruptly acuminate at the apex; flowers in axillary 

 and terminal clusters; bracts about 8 mm. long and about as broad, 

 4-winged, coarsely toothed and occasionally with a few additional 

 processes, with a broad open sinus at the apex; free portion 1-2 

 mm. long. 



The fruit would associate this species with A. canescens, A. 

 occidentalis, and A. tetraptera, but the leaves are quite different 

 in shape. The plant looks in general habit somewhat like A. 

 confertifolia, but the fruiting bracts are altogether different. It 

 grows in arid valleys at an altitude of about 1,200 m.

Endolepis phyllostegia (Torr.) Rydb. comb. nov. 

 Obione phyllostegia Torr. in Wats. Bot. King Exp. 291. 187 1. 

 Atriplex phyllostegia S. Wats. Proc. Am. Acad. 9: 108. 1874. 

 This species should be transferred from Atriplex to Endolepis, 

 as sepals are present in the pistillate flowers. 



Eurotia subspinosa sp. nov. 



A dioecious shrub, 6-10 dm. high; branches ascending or 

 spreading, becoming more or less spinescent, finely grayish steliate- 

 tomentose but without longer hairs; leaves linear or oblong, 

 obtuse, entire, 1-3 cm. long, or the secondary ones only 5 mm. long 

 and comparatively broader, with revolute margins; flower clusters 

 axillary, those of the staminate plant crowded and forming simple 

 leafy spikes; fruiting bracts lanceolate, about 6 mm. long; horns 

 usually about 2 mm. long. 



This species is more decidedly shrubby than E. lanata (Pursh) 

 Moq. and evidently always dioecious, has ascending or spreading 

 branches, which become spinescent, lacks the long hairs inter- 

 mixed with the stellate pubescence characteristic of E. lanata, 

 and has usually longer horns. In E. lanata the branches are erect, 

 and the plant is shrubby only at the base. The predominantly
