1 1 4 Plants Collected in Southeastern Utah. [zoe 



tinction between this and L. alyssoides; for I find myself always 

 in doubt concerning certain plants. 



7. LesouerELLA MONTANA Watson. This is not uncom- 

 mon through southeastern Utah, and is usually found under the 

 cedars and pinons. 



8. Erysimum asperum DC. A few plants were noticed in 

 a rocky cafion. They had shorter pods than any before seen. 



9. Sisymbrium linifolium Nutt. This was seen here and 

 there through the region, on the mesas. 



ID. Streptanthus cordatus Nutt. This was generally 

 found on cedar-covered mesas. 



11. Streptanthus eongirostris Watson. Reported in 

 the general notes of a trip through southeastern Utah, Zoe iii, 

 4, as Arabis longirostris Watson. Thompson's Springs. It is 

 common on the adobe desert and also on the mesas. 



12. Theeypodiumambiguum. Watson. Thompson's Springs. 

 13 Theeypodium aureum Eastwood. Along McElmo 



Creek. Most common at Mancos, where the type was collected. 



14. BiscuTELEA WiSLizENi Benth. & Hook. On a sandy 

 fiat in Court House Wash, and along McElmo Creek in a similar 

 situation. 



15. Cleomeeea peocasperma Watson. The stamens sur- 

 pass the petals, the pedicels are horizontal and about as long as 

 the defiexed stipe, the seeds are not tessellated, but may not be 

 sufficiently ripe. In all other characteristics it resembles the 

 above-named species. It is not C oocarpa as that species is rep- 

 resented in the Herbarium of the California Academy of Sciences, 

 Collected between Thompson's Springs and Moab. 



16. PoLYGAEA ACANTHOCLADA Gray. This spiny plant 

 was collected in Montezuma Canon on a rocky hill. 



17. Malvastrum LEPTOPHYEEUM Gray. Collected in Court 

 House Wash and along McElmo Creek. 



18. Sph^raecea Munroana Spach. Collected after leav- 

 ing Moab, a form with light pink fiowers. The red-fiowered 

 form is common through the whole region.
