6(5). Lateral walls of the carpels firm, persistent; seeds without an aril-like 

 envelope; flowers axillary and solitary or more or less aggregated 

 in racemes, spikes or heads; calyx usually angulate, sometimes 

 much-accrescent, the lobes commonly erect or connivent over the 

 fruit; carpels muticous or acute to birostrate or biaristate, often 



rugose or muricate, indehiscent or slightly dehiscent at apex

6. Lateral walls of the carpels fragile, soon disappearing or becoming lacerate; 

 seeds usually more or less enveloped by an arilliform often 

 reticulate endocarp, this sometimes closely adherent to the seed 

 coat; fruit discoid to nearly hemispheric, depressed, the carpels 

 incurved and with a dorsal hispid spur 7. Anoda 



1. Iliamna Greene Wild Hollyhock 



About 7 species mainly in western United States. 



1. Iliainna grandiflora (Rydb.) Wiggins. 



Erect herbaceous perennial 1-2 m. tall, somewhat suffrutescent at the base; 

 stems glabrate at base, sparsely stellate-pubescent above; leaves 6-10 cm. wide, 

 deeply 5- or 7-lobed, sparsely stellate-pubescent, the hairs more scattered on 

 the upper surface than beneath; leaf lobes lanceolate to triangular, the midlobe 

 from slightly longer to twice as long as the lateral lobes, coarsely toothed with 

 rounded-triangular abruptly apiculate teeth; petioles to 15 cm. long; stipules 

 lance-linear, deciduous; flowers in small clusters in axils of upper leaves and 

 in an interrupted congested spicate or corymbose terminal inflorescence; pedicels 

 stout, 2-15 mm. long, densely pubescent with stellate hairs; involucellate bracts 

 lanceolate, 8-12 mm. long, 2-3 mm. wide, less densely stellate-pubescent than the 

 calyx; calyx densely villous-hirsute with long-rayed stellate hairs, 1-1.5 cm. broad 

 at anthesis, the lobes broadly triangular-ovate and abruptly acute to short- 

 acuminate; petals broadly obovate, rounded, about 3 cm. long, pink, densely 

 villous on the margins of the claws; stamineal column stout, about 1.5 cm. long, 

 hirsute at the base with stiff long-rayed stellate hairs; fruit subglobose, 12-15 mm. 

 broad, about 10 mm. high, deeply retuse at apex; carpels membranous, oblong, 

 half as wide as high, smooth on the sides, pubescent on the back with coarse erect 

 simple hairs about 3 mm. long, dehiscent to the base or nearly so; seeds reniform, 

 2.5-3 mm. long, brown, muricate with scattered short simple hairs, usually 3 in 

 each carpel, the surface of the seed coat distinctly tesselated by the outlines of 

 the cell walls. 



In damp or wet places in mts. of n. N. M. and Ariz., May-Aug.; also Colo, 

 and Ut. 



2. Sidalcea Gray Checker-mallow. Prairie-mallow 



Erect perennial herbs; leaves long-petioled, with orbicular crenately incised to 

 parted or divided blades; flowers in bracteate spikelike racemes, all perfect or with 

 perfect and pistillate flowers or unisexual; calyx without bracteoles; petals purple 

 to rose or white; stamens usually in an upper and a lower series on the stamen 

 column; fruit of 5 to 9 1 -seeded indehiscent carpels. 



About 25 species in western North America. Some of the species, namely 5. 

 neomexicana, are reported to be used as greens by the Indians.

 pubescent 1. 5'. Candida.
