Dear all

The lastest edition of a major botanical journal, Novon volume 15 number 2,
features three new species of popular genera. Abstracts of the articles
follow.

pp. 279-281:
Calochortus mendozae Espejo, López-Ferrari & Ceja, a new species from the
municipality of San Nicolás Tolentino in the state of San Luis Potosí,
Mexico, is described and illustrated. The new species grows on gypseous
soils in xerophytic scrub. Calochortus mendozae is placed in section
Cyclobothra subsection Ghiesbreghtiani and is closely related to C. hintonii
Bullock ex Ownbey, with which it is compared.

pp. 324-326:
A new species from Chile, Leucocoryne talinensis, is described and
illustrated. It is known from Talinay and Fray Jorge in Limarí Province,
from roadsides and adjacent fields. Its chromosome number and relationship
to the most closely related species are discussed.

pp. 354-357:
Tigridia suarezii (Iridaceae, Tigridieae) is a new species from Mexico. Its
distinguishing features are the dark purple, almost black color of the
spreading tepal limbs and the white to cream floral cup with dark purple
spots and stripes. It is morphologically similar to T. alpestris subsp.
obtusa and T. venusta, from which it differs in the more robust habit of the
plant, the shape, length, and width of the tepals, and the length of the
anther, filament column, and style branches. Tigridia suarezii and T.
venusta inhabit the understory in pine-oak forests in an altitudinal range
from 2080 to 2800 m, whereas T. alpestris subsp. obtusa grows on exposed
rocky slopes above 3000 m. Tigridia suarezii is known only from the state of
Jalisco.

And in Novon volume 15 number 1 pp. 168-172:
Freesia marginata (Iridaceae: Crocoideae) is a new species from the Breede
River valley near Worcester in Western Cape Province, South Africa. A local
endemic of succulent karoo shrubland, it resembles F. caryophyllacea in its
flowers and short, prostrate leaves, but it is distinguished from all other
species of Freesia by the leathery, somewhat glaucous leaves with a
prominent submarginal vein. The four species previously placed in the genus
Anomatheca are recognized in Freesia as the new subgenus Anomatheca. Three
of the species, F. grandiflora, F. laxa, and F. verrucosa, are segregated
into section Anomatheca, and F. viridis is placed in the new section Alatae.
