Dousar Other clades are the narrowly distributed South American Pterocactus; a clade of Maihueniopsis-Tephrocactus including Puna ; and two clades containing the more widely distributed opuntioids found in both North and South America.

Forragicultura e Pastagens As indicated, a cuticle can occur on the inner side of epidermal cells, as for Homalocephala texenis and Uebel- mannia gummosa Mauseth a. A number of pasragens transitions have been hy- pothesized for the opuntioid lineages.

The analysis strongly supports recognizing many of the segregate genera formerly proposed for opuntioids. Developmentally variable, polymorphic woods in cacti. Nordic Journal of Botany 3: This is regrettable because some opuntias are dominant perennials in drylands of the New World or have become weedy invaders elsewhere and spread by grazing habits of livestock Nobel These stem joints are seasonally deciduous in Brasiliopuntia.

Revised Biogeographic Models Based on Molecular Studies Evolution of the cacti from ancestral populations of por- tulacaceous ancestors is being supported again and again by molecular studies of a variety of genes and other DNA sequences Applequist and Wallace A basal lineage for the subfamily appears to include the species referable to the genera Austrocylindropuntia and Cumulopuntia, both native to the Peru-Bolivia-Chile Andean regions.

Hypothesized intergeneric relationships within some North American columnar cacti based on analyses of rpl16 intron sequences. Angiosperm bio- geography and past continental movements. Narrow pith and absence of mucilage cells have been treated as primitive characters for cactus stems, and this can also be tested by character mapping on cladis- tic models.

Many researchers, for convenience, would pre- fer to have fewer and larger genera, but many smaller gen- era may have to be recognized to represent the true evolu- tionary lineages.
