Draba streptobrachia (Brassicaceae), a new species from Colorado

Draba streptobrachia Price is an alpine species endemic to Colorado, U.S.A. It was treated byHitchcock (1941) asDraba spectabilis var.dasycarpa (Schulz) C. L. Hitchc., but is distinct fromD. spectabilis Greene in morphology, habitat, and chromosome number (g = ca 32 inD. streptobrachia, versusg = 10 and 16 inD. spectabilis) and therefore has been raised to the rank of species. Pollen fertility inD. streptobrachia is at or near zero and anthers consistently fail to dehisce, but fertile seeds are still produced, suggesting that the taxon reproduces by agamospermy.     

Physaria pulvinata (Brassicaceae), a new species from southwestern Colorado

Physaria pulvinata is described from isolated, grayish, argillaceous shale outcrops in Dolores and San Miguel Counties of southwestern Colorado. It may be distinguished from the relatedP. intermedia by its caespitose, mound-forming habit, and fromP. navajoensis in that its fruits are pubescent. The new species keys toP. rectipes in available floras and monographs, and differs from that species in being mound-forming from a manybranched caudex.     

A new species of Noccaea (Brassicaceae) from South Anatolia, Turkey

Noccaea camlikensis sp. nov. (Brassicaceae) is described and illustrated from a localized serpentine range in southern Turkey. Its close relationship to N. cariensis , from which it differs in leaf and carpological characters, is discussed. The protologue of this fairly unknown species can now be amended to cover better the morphological variability of this taxon. A comparative study of seed-coat anatomy advocates its move from Thlaspi to Noccaea ; the relevant combination N. cariensis (Carlström) Parolly, Nordt & Aytaç is made. The ecology of both vicarious species is discussed and their distribution mapped.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 150 , 409–416.
