A re-assessment of the putative Carex flava agg. (Cyperaceae) hybrids at Malham Tarn (v.c. 64): A morphometric analysis. Watsonia 23: 505–516

Carexfiava L., a rare species in the British Isles, is currently only recognised from one extant population. The presence of three putative C. flava x C. viridula Michx. subsp. brachyrrhyncha (Celak.) B. Schmid hybrid ( = c. x alsatica Zahn.) populations suggests that it may have formerly been more...

Description
Summary:Carexfiava L., a rare species in the British Isles, is currently only recognised from one extant population. The presence of three putative C. flava x C. viridula Michx. subsp. brachyrrhyncha (Celak.) B. Schmid hybrid ( = c. x alsatica Zahn.) populations suggests that it may have formerly been more widespread. Alternative taxonomic treatments have been considered populations, including the possibility that they could be C. flava subsp. jemtlandica (Palmgr.) P. D. Sell, a Fennoscandian taxon not previously recorded in this country. Uni-and multivariate statistical ana lyses were used to elucidate the taxonomic affinity of the largest of these
