Lesouerella aurea. 



Annual, sending up several erect or slightly spreading stems 

 3-4 dm. high, each terminating in a raceme of bright yellow 

 flowers : leaves narrowly obovate to oblanceolate, 1-3 cm. lon , 

 3-10 mm. broad, upper ones oblong, decurrent, subsessile, obtuse, 

 entire to slightly sin uate -dentate ; leaves, stems and outside of 

 sepals covered with a close fine soft stellate pubescence, tomentulose 

 on the younger parts of the inflorescence : flowers in terminal 

 racemes, crowded at the end of the rachis, the latter elongating in 

 fruit; proper peduncle about 1 cm. long, rachis (in specimens 

 which have only a few mature pods) 1 dm. long ; pedicels 3-6 

 mm. long in flower, ascending, 10-12 mm. long in fruit, strongly 

 recurved : sepals oblong, obtuse, 3 mm. long, yellowish : petals 

 obovate-spatulate, 5 mm. long, half as broad, blade decurrent into 

 a kind of winged claw: filaments subulate, anthers sagittate: 

 ovary glabrous, containing 3-8 pendulous ovules : pod globose, 3 

 mm. in diameter, not stipitate, glabrous, tipped by the 2-3 mm. 

 long persistent style ; seeds 2-5 ovoid, light brown. 



Collected on the south fork of Tularosa Creek three miles east 



Mescal 



July 30. No. 245. 



This species is properly classed in the same group with L. 

 recurvata (Kngelm.) Wats, and should follow that species, being 

 somewhat intermediate between it and L. Lindhcimai (Gray) 

 Wats. It is easily distinguished from the latter by its strongly re- 

 curved fruiting pedicels, its less dentate leaves, slender stems, 

 smaller flowers and softer, not lepidote pubescence. From L. 

 recurvata it is separated by stouter, erect, simple (?) stems (the 

 stems in my specimens are not branched but short branches are 

 beginning to appear in the upper axils, indicating that they may 

 branch somewhat as in L. recurvata) much larger leaves, terminally 

 clustered and more numerous flowers and the peculiar soft pubes- 

 cence which is not lepidote or scabrous. 



Mentzelia perennis. 



Perennial ; stems caespitose, erect or slightly spreading, branched 

 above scabrous with retrorsely barbed hair's or almost glabrous, 

 bark thin and white : leaves alternate, linear, 3-10 cm. long, 2-3 

 mm. wide, entire or with 10 or less, rounded tooth-like lobes, 2-5 

 mm. long scabrous with barbed hairs : flowers terminal or in the 

 upper axils producing a pseudo-cymose inflorescence ; peduncles
