Abstract
Dalea verticillata is described and illustrated as a new species from Oaxaca, Mexico. Dalea verticillata is similar to D. filiciformis, but it is distinguished by having whorled leaves (vs. alternate in D. filiciformis), with a greater number of leaflets ((31–)39–63(–69) vs. (11–)13–29(–37)), longer stipules (4.5–8 mm vs. 0.3–1.5 mm), reflexed (vs. ascending), persistent (vs. deciduous), terminal panicle inflorescences (vs. axillary racemes), and the wing petals subelliptic (vs. ovate). This is the second species of the hitherto monospecific subgenus Psoropteris, and the whorled-leaf character is recorded for the first time in the genus Dalea.
期刊介绍:
Since 1931, Brittonia, assuming the broadest possible definition of the field of systematic botany, has been an important outlet for the publication of original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography. Each issue contains articles by the staff of The New York Botanical Garden and outside contributors, book reviews, and announcements.
