Flora of North America species comparison

usually erect or ascending, rarely subdecumbent, unbranched or branched distally, (sometimes inflated).

basal and cauline;

petiolate, subsessile, or sessile;

basal rosulate or not, petiolate, blade margins entire, dentate, sinuate, lobed, or pinnatifid;

cauline petiolate, subsessile, or sessile, blade (base sometimes sagittate or amplexicaul, rarely subauriculate), margins entire, dentate, or lobed.

(corymbose, sometimes with a terminal cluster of sterile flowers from grouping of dark purple flower buds, rarely proximalmost flowers bracteate), elongated in fruit.

sepals usually erect or ascending, rarely spreading, oblong or ovate to lanceolate, (usually forming urceolate calyx, sometimes keeled), lateral pair saccate or not basally;

petals yellow, brown, purple, lavender, white, yellowish green, or, rarely, pinkish, linear to oblanceolate, (often channeled and crisped, rarely neither, equal or abaxial (lower) pair slightly shorter than adaxial (upper) pair, longer than sepals), claw often well-differentiated from blade (sometimes longer and wider than blade, entire);

stamens tetradynamous or 3 unequal pairs (rarely subequal);

filaments not dilated basally, (usually distinct, sometimes adaxial or both median pairs connate);

anthers oblong, (equal or adaxial pair smaller, apex obtuse or apiculate);

nectar glands usually confluent, subtending bases of stamens.

erect, ascending to divaricate, or reflexed, slender or stout.

sessile, linear, usually smooth, rarely torulose, usually terete, latiseptate, or angustiseptate, rarely 4-angled;

valves each with distinct or obscure midvein, glabrous or sparsely pubescent;

replum rounded;

septum complete, (veinless);

ovules 14–60[–210] per ovary;

style obsolete or distinct;

stigma capitate or not, entire, subentire, or 2-lobed (lobes opposite valves or replum).

uniseriate, usually flattened (plump in C. californicus), usually not winged, rarely margined, oblong, ovoid, or, rarely, subglobose;

seed coat not mucilaginous when wetted;

cotyledons incumbent or obliquely so, (entire or, rarely, 3-fid).
