Fwd: New species

I got this message from another gardening mailing list.  It has some info 
about new Irid species.  I thought some of you might be interested...  (I 
myself was surprised to hear Anomatheca are now Freesia).

>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

>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.
