Species ad 12, sat varialiles, regiones temperatas Europe, Afriez borealis, Asiz occidentalis, et 
frigidas Americz borealis et Montium Himalay:e incolunt. DC. Prod.i. 136. Walp. Rep. i. 124; 
Ji. 709: Ann.iv.192. Journ. Linn. Soc. v. 126. Genus in sectiones 2 dividitur, nempe Cleiri, DC. 
Heiehb. Fl. Germ. ii. t. 45, siliqua ancipiti, stylo 0, seminibus immarginatis; et Cheiroides, DC., 
siliqua tetragona, stylo filiformi, seminibus marginatis (DicirgoaxrRuS, Webb, Phytogr. Canar. i. 65. 
1. 5, 6). 
Inter Cheiranthum et Erysimum nullum est discrimen habitu, floribus, siliquisve, — Differunt semi- 
nibus in Erysimo semper turgidis, cotyledonibus incumbentibus; in Cheirantho s:wpius compressis, 
eotyledonibus aceumbentibus v. rarius ineumbentibus. (C.pygm«eus cotyledones habet aceumbentes et 
ineumbentes, rectas et, convolutas in eadem siliqua! : ;

branaceo ; stylo brevi; stigmate bilobo. Semina uniseriata, compressa, immarginata.—Herba

wunguieulata, interdum 0. Stamina 1-6. Siliqua brevis v. elongata, teretiuscula, in paucis

smpissime flavi, 
Genus difficillimum amphigeum, species vix 20 bene distinetas complectens (etsi ad 80b auctori- 
bus variis propositee sint), quarum plurimee a. CocAlearia characteribus nullis technicis distinguendze
