Musa×georgiana,a new intersectional hybrid banana with edible banana breeding relevance and ornamental potential

Five new species of the family Poaceae are described from the Russian Far East: Agrostis czernjaginae Prob. (sect. Trichodium) (revealed chromosome number 2n = 42) from thermal springs of Kamchatka, Bromopsis kozhevnikovii Prob. (sect. Rhizomatosae) from high mountains of Dusse-Alin Range in the Khabarovsk Territory, Poa amurica Prob. (sect. Stenopoa) from Selemdzha River in the Amur Region, Koeleria dersu Prob. et Prokopenko (sect. Koeleria) from the eastern macroslope of Sikhote-Alin in the Primorye Territory, Agrostis × lapenkoi Prob. (probably, intersectional hybrid: A. giganteaRoth × A. clavata Trin.) from Ussuri River basin, also in the Primorye Territory.

Three New Species

Three new species, namely Cousinia boyerahmadica, C. deluensis and C. masulehensis (Asteraceae-Cardueae), are described and illustrated from Iran. The diagnostic characters of these new taxa are compared with their relatives. Their ecology, phytochoria and phenology are presented. Cousinia macrolepis is reported as new to Iran. Cousinia beckeri, which was excluded from C. sect. Cynaroideae on the basis of a wrong citation, is returned to the section. Cousinia subinflata, which was also excluded from the section as an intersectional hybrid, is rehabilitated as a distinct species. The distribution map and conservation status of these taxa according to the IUCN categories are also provided.

Agave Sisalana

New cytotaxonomical determinants are presented for the following taxa of Agave: (I) section Rigidae: Agave fourcroydes Lemaire (5x = 150), first karyotype; Agave angustifolia Haworth (sensu Gentry), new count (6x = 180), first karyotype; Agave angustifolia Haworth var. marginata Hort. (2x = 60); and Agave tequilana Weber, new count (2x = 60), first karyotype; (II) section Sisalanae: Agave sisalana Perrine (5x = 150), first karyotype; and (III) intersectional hybrid: Agave hybrid 11 648 new count (2x = 60), first karyotype. Chromosomes are classified and arm number, chromatin length, and variability are discussed. These results suggest (i) a speciation process via limited rearrangements and point mutations in the small chromosomes of the complement, within the euploidy level rather than karyotype diversification and (ii) a reconsideration to assign them to the 2C level of Stebbins karyotype classification. Key words: fiber agaves, karyotype analysis.
