Diversity of growth <strong>form</strong>s<br />

Ten growth <strong>form</strong>s of vascular<br />

plants in the Ecuadorian paramos<br />

• stem rosette (e.g., Espeletia<br />

pycnophylla)<br />

• (b) basal rosette (e.g. Puya hamata)<br />

• (c) tussock (e.g., Calamagrostis<br />

coarctata )<br />

• (d) acaulescent rosette (e.g.,<br />

Hypochaeris sessiliflora)<br />

• (e) cushion (e.g., Plantago rigida)<br />

prostrata)<br />

• (h) erect herb (e.g., Bartsia laticrenata)<br />

• (i) prostrate herb (e.g., Geranium<br />

multipartitum)<br />

<strong>Growth</strong> <strong>form</strong>: cushion bogs<br />

Biogeography of Oreobolus inferred from<br />

molecular phylogeny suggests a longdistance<br />

dispersal from Australasia to southern South<br />

America and subsequent northward migration to<br />

páramo of northern Andes and Central America;<br />

<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)

Elaphoglossum sp<br />

(Lomariopsidaceae, WT)<br />

Ferns<br />

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 />
