Scutellaria cuevasiana and Scutellaria sublitoralis (Lamiaceae), two new species from Jalisco and Nayarit, Mexico

Abstract

Scutellaria cuevasiana J. G. González et A. Vázquez and Scutellaria sublitoralis J. G. González
are described and illustrated. Scutellaria cuevasiana fits best within section Uliginosae (Epling) Epling. It is
morphologically close to S. blepharophylla Epling, S. rosei Fernald and S. seleriana Loes. It differs from them by
its magenta corollas, small and sessile floral bracts, longer petioles and bigger leaves. Scutellaria sublitoralis does
not manifest any clear morphological affinity with species of the sections enumerated by Epling. It could be related
to species in sections Pallidiflorae Epling or Uliginosae, particularly with the “Scutellaria ovata” or “Scutellaria
caerulea” species groups defined by Paton. It is morphologically similar to S. pallidiflora Epling; however, it can be
recognized by wider leaves with usually cordate to subcordate bases, persistent floral bracts, floral axis and calyces
without glandular-capitate hairs, longer corollas, and narrower toward the throat.
