Previousknowledge.Therangeofthiscomparativelyrecentlydescribedgenus(Ma- son, Madrono 23:105-108, 1975) has been expanded steadily eastward by work of NM botanists (N.M. Native Plant Advisory Committee, A Handbook ofRare and Endemic Plants ofNew Mexico, 1983). Until the collection reported here, the east- NM ernmost record for the species was in west central in Socorro Co. All previous collections are from rhyolitic rock. Significance.

NM Significance. First record for for a species reported in several regional floras as naturalized from Europe and now widely distributed in North America. Martin and Hutchins (A flora ofNew Mexico, vol. 1, 1980) note that this species is to be expectedin NM. Cooperia drummondii Herb.

The species is reported for the state in the Flora ofthe Great Plains (Great Plains Flora Association 1986) and in the Manual ofthe Vascular Plants of Texas (Correll and Johnston 1972). Martin and Hutchins (A Flora ofNew Mexico, vol. 1, 1980), however, indicate no certain records forNM, and map the species as "to be expected" in the southeastern portion ofthe state. This record confirms the presence ofthe species in NM, and extends its range westward by about 200 km beyondthat predictedby Martin and Hutchins.

(Spellenberget al., Sida 11:455-470, 1986) were also collected in the same area, all an indication ofa hitherto unrecognized extension ofa more western flora into this portion ofNM.
