Data from: Pennellia yalaensis (Brassicaceae: Halimolobeae), a new species from the Andes of Northern Argentina

Pennellia yalaensis, a new species of Brassicaceae from Jujuy Province in
Argentina, is described and illustrated, and its phylogenetic
relationships with nearest relatives are discussed. This novelty is
morphologically related to P. boliviensis and P. brachycarpa, which also
grow in Central Andes of Argentina. However, P. yalaensis clearly differs
from both species by the plant height, inflorescence type, and petal
length. In addition, trichomes of the basal leaves distinguish the new
species from P. boliviensis, and fruit length and number of ovules/seed
from P. brachycarpa. Phylogenetic analyses, based on DNA sequences of
nuclear ITS and plastid trnL-F regions, confirmed these affinities.
