<strong>Growth</strong> <strong>form</strong>s, biogeography and evolution<br />
Valeriana microphylla (Wte)<br />
Valeriana plantaginea<br />
Asian origin of the genus (and family) and<br />
subsequent migration via Europe to North America.<br />
From North America there may have been two<br />
colonization events of the South American continent<br />
(páramo branches in bold) (From Bell & Donoghue,<br />
2005 in Sklenar & al 2011)
<strong>Growth</strong> <strong>form</strong>s, biogeography and evolution<br />
Gentiana sedifolia (WTe)<br />
Gentianella hirculus (WTe)<br />
G. rapunculoides Gentianella rapunculoides<br />
Gentianella hyssopifolia<br />
Gentianella originated in<br />
Asia, then dispersed to<br />
other north temperate<br />
regions, and colonization of<br />
South America likely<br />
occurred via North America<br />
(in Sklenar & al 2011)
Gentianaceae: genus Halenia (N)<br />
Asia : 2 species<br />
N America: 1 species<br />
C America: 15 species<br />
S America: 50 species including 39 in paramos<br />
Richness diversity suggested neotropical element while<br />
Reconstructed phylogeny suggests that Halenia<br />
originated in eastern Asia and then immigrated via North<br />
and Central America to South America with three<br />
independent immigrations from Central America to the<br />
northern Andes (von Hagen & Kadereit, 2003 in Sklenar<br />
& al 2011)

Jamesonia imbricata (Pteridaceae, N)<br />
Cladogram of the Jamesonia-Eriosorus<br />
complex suggests two colonizations<br />
and three independent radiations in the<br />
Andes. Repeated evolution of the<br />
“jamesonia” growth <strong>form</strong> is inferred<br />
which renders both<br />
Jamesonia and Eriosorus paraphyletic<br />
