`vegaer`

above.`autopoll`

selfing pollination, an ordered factor with levels

.`lign`

a binary factor with levels

`0:1`

, indicating if plant is woody.`piq`

a binary factor indicating if plant is thorny.

`ros`

a binary factor indicating if plant is rosette.

`semiros`

semi-rosette plant, a binary factor (

`0`

: no;`1`

: yes).`leafy`

leafy plant, a binary factor.

`suman`

summer annual, a binary factor.

`winan`

winter annual, a binary factor.

`monocarp`

monocarpic perennial, a binary factor.

`polycarp`

polycarpic perennial, a binary factor.

`seasaes`

seasonal aestival leaves, a binary factor.

`seashiv`

seasonal hibernal leaves, a binary factor.

`seasver`

seasonal vernal leaves, a binary factor.

`everalw`

leaves always evergreen, a binary factor.

`everparti`

leaves partially evergreen, a binary factor.

`elaio`

fruits with an elaiosome (dispersed by ants), a binary factor.

`endozoo`

endozoochorous fruits, a binary factor.

`epizoo`

epizoochorous fruits, a binary factor.

`aquat`

aquatic dispersal fruits, a binary factor.

`windgl`

wind dispersed fruits, a binary factor.

`unsp`

unspecialized mechanism of seed dispersal, a binary factor.

Most of factor attributes are not disjunctive. For example, a plant can be usually pollinated by insects but sometimes self-pollination can occured.
