Seeds generally with aril
Genera in family: 8 genera, 575 species: especially temp. Often heterostylous.
Annual, perennial herb, shrub; roots fibrous or woody; bulbs, tubers, or rhizomes often present
Stem sometimes 0 or very short
Leaf petioled: stipules 0 or small; leaflets 3, generally ± obcordate in CA, generally entire, generally green
Flower: petals clawed; stamens 10; ovary chambers 5, styles 5, free, erect or curved

| YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps). |
