SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

Menonvillea filifolia subsp. marticorenae is described, and its distinguishing characters from M.filifolia subsp. filifolia are given. The genus Grammosperma is reduced to synonymy of Sarcodraba. A key to the four species of Sarcodraba is presented, and the new combination S. dusenii is proposed. Skottsbergianthus sorianoi is lectotypified and reduced to synonymy of Xerodraba colobanthoides.

A synopsis of the South American Lepidium (Brassicaceae)

Fifty native and 12 naturalized species of Lepidium grow in South America, and a key to all 62 species is presented. Three new species from Argentina (L. hickenii, L. pedersenii, and L. santacruzensis) and two from Peru (L. cuzcoensis and L. werffii) are described, illustrated, and their relationships to nearest relatives are discussed. The new combination Lepidium crassius is proposed. Furthermore, 19 taxa (Coronopus didymus var. macrocarpus, C. didymus var. procumbens, L. abrotanifolium var. steinmannii, L. affine, L. argentinum, L. auriculatum, L. bonariense var. pseudovirginicum, L. calycinum var. integrifolium, L. costaricense, L. cumingianum var. orbiculatum, L. cumingianum subsp. berteroanum, L. depressum, L. myrianthum, L. neglectum, L. parodii, L....

The genus Sisymbrium in South America, with synopsesof the genera Chilocardamum, Mostacillastrum, Neuontobotrys, and Polypsecadium (Brassicaceae)

Based on extensive molecular and morphological data, all of the native South American species previously assigned to Sisymbrium (tribe Sisymbrieae) are assigned to the genera Chilocardamum, Mostacillastrum, Neuontobotrys, and Polypsecadium of the tribe Schizopetaleae (Brassicaceae). Akey distinguishing these four genera is presented. For each genus, a revised synopsis, an expanded generic description, a key to species, and an enumeration of all taxa is given. Polypsecadium zoellneri is described as a new species from northern Chile, and its distinguishing characters from its nearest relative P. gilliesii are discussed. The following 36 new combinations are proposed: Chilocardamum castellanosii, C. longistylum, C. onuridifolium, Mostacillastrum andinum, M....
