Summary Ribes (currants and gooseberries) are telial hosts for the introduced and invasive white pine blister rust fungus, Cronartium ribicola. Knowledge of wild and introduced Ribes helps us understand the epidemiology of blister rust on its aecial hosts, white pines, and develop disease control and management strategies. Ribes differ by species in their contribution to initial establishment and subsequent intensification of blister rust. Their significance to pine infection depends on their inherent capacities to become infected and support spore production, their abundance and environmental interactions. Ribes and white pines are adapted to disturbance and frequently co‐occur in forest and woodland ecosystems. Differences in light and moisture requirements affect how long various species of Ribes occupy a site. Natural or artificial selection increases rust resistance in white pines, Ribes, and other host genera; but selection also affects virulence and aggressiveness of C. ribicola. Blister rust pathosystems evolve. Local pathosystems wherein the rust and its hosts coexist with reduced damage could arise by several processes.

“…Hitchcock (1935, 1951) included P.sandbergii and P.incurva in P.secunda . Marsh (1950, 1952) and Kellogg (1985a, b) quite independently lumped most of these taxa in P.secunda without any infraspecies (followed by Lesica 2012, for Montana). Kellogg’s work, based on morphometric analyses, separated P.curtifolia ; Marsh maintained that and also P.tenerrima .…”

Poa secunda J. Presl (Poaceae): a modern summary of infraspecific taxonomy, chromosome numbers, related species and infrageneric placement based on DNA

Poasecunda J. Presl. s.l. is a morphologically highly variable bunchgrass that is a valuable forage species in western North America. There has been much controversy as to whether multiple taxa should be recognised and at what rank in this taxonomically challenging apomictic complex. Here we propose an infraspecific classification for Poasecunda of six varieties within two subspecies, juncifolia and secunda. New combinations are P.secunda vars. ampla, gracillima, juncifolia, nevadensis and scabrella. Conflicting plastid and nrDNA phylogenies show that P.sect.Secundae is of ancient hybrid origin. Based on this and its distinct morphology, the section is raised to the rank of subgenus. A key is presented for P.secunda infraspecies and closely related non-arctic species. Suppl. materials are provided of chromosome counts for Secundae taxa and D.D. Keck specimen annotations of taxa here included in P.secunda.

“…Cypripedium calceolus var. parviflorum is reported as flowering somewhat earlier than C^passerinum (Lesica and Shelly 1991), but on the KNF where they grow together they were flowering concurrently in 1995. Flowers are needed for reliable identification, thus, occurrences found late in the season in fruit (e.g.…”
