A. Sepals orbicular, very small, obtuse. 

 B. Corolla twice as long as thick; sepals appressed. 



1. amoena, De Smet. Nearly stemless, with numerous 

 offshoots: Ivs. in small but dense rosettes: flowering 

 branches slender, 4-8 in. long; fls. 1-8, in slender 

 racemes; corolla red, 4-5 lines long. Native of Mex. 

 This species was intro. into cult, nearly 40 years ago. 



BB. Corolla little longer than thick; sepals not appressed. 



2. microcalyx, Brit. & Rose (E. Purpusii, Brit.). 

 Shortly caulescent, sometimes 1 ft. high: corolla yellow- 

 pink, 4 lines long. Native of Mex. 



AA. Sepals linear to ovate. 

 B. Fls. axillary, arranged in loose spikes or racemes. 



c. The fls. in spikes. 

 D. Plant not caulescent, glabrous throughout. 



3. mucronata, Schlecht. Caulescent, glabrous 

 throughout: basal Ivs. in a dense rosette 4-8 in. long: 

 fls. sessile; corolla 1 in. or more long, reddish tinged 

 with yellow. E. Mex. 



DD. Plant caulescent, pubescent throughout. 



4. coecinea, DC. (Cotyledon coecinea, Cav.). St. 

 1-2 ft. high, finely grayish pubescent: Ivs. oblanceolate, 

 largest 8-9 in. long: infl. a spike of 15-25 fls. Common 

 in Cent. Mex. Page 870. 



5. pubescens, Schlecht. (Cotyledon pubescens, Baker). 

 A similar species is sometimes cult., with obovate-spatu- 

 late Ivs. 



cc. The fls. in racemes. 



D. Species caulescent. 



E. Infl. compound below; corolla pale. 



6. Iinguaef61ia, Lem. Sts. 1 ft. or more high, very 

 leafy: Ivs. thick, fleshy, green, nearly terete at base: 

 flowering branches long and drooping, each consisting 

 of a simple raceme: fls. cream-colored. Mex. This 

 species has long been in cult., and has not been collected 

 wild in recent years. It is so very different from the 

 other echeverias of Mex. that we are led to suspect 

 that it may be of hybrid origin. 



EE. Infl. simple throughout; corolla bright-colored. 

 F. Plant pubescent throughout. 



7. pulvinata, Rose (Cotyledon pulvinata, Hook.). 

 Sts. 4-6 in. high, somewhat branching, becoming naked 

 below: young branches, Ivs. and sepals covered with a 

 velvety pubescence: Ivs. clustered in rosettes at the top 

 branches, about 1 in. long, very thick: fls. in a leafy ra- 

 ceme; corolla scarlet, sharply 5-angled. Mex. This is 

 a very distinct echeveria, with a remarkable pubescence. 



8. Pringlei, Rose (Cotyledon Pringlei, Wats.). This 

 is perhaps nearest E. pulvinata, although not so pubes- 

 cent nor so attractive a plant. 



FF. Plant glabrous throughout. 



9. atropurpurea, Baker (Cotyledon atropurpurea, 

 Baker. E. sanguinea, Morr.). Sts. 4-8 in. high, 

 glabrous throughout: Ivs. aggregated at the top of the 

 st. in a dense rosette, usually dark purple above, some- 

 what glaucous: flowering branches elongated; sepals 

 somewhat unequal; corolla bright red, strongly angled. 

 Probably native of Mex., but known only from cult, 

 specimens. Page 870. 



DD. Species not caulescent. 



10. lurida, Haw. (Cotyledon lurida, Baker). Plants 

 stemless, glabrous and glaucous throughout: Ivs. 

 forming a flat, rather open rosette, narrowly oblong, 

 2-4 in. long, acute, tinged with purple, especially when 

 old: flowering branches 12-32-fld.; sepals thick, spread- 

 ing or even reflexed; corolla bright red. Known only 

 from garden material, but undoubtedly from Mex. 

 B.R. 27:1. 



11. racemdsa, Schlecht. & Cham. This is similar to 

 E. lurida, and was considered by Baker to be a syn- 

 onym; but they are here kept distinct. The material 

 of E. racemosa now in cult, was secured at the type 

 locality of the species, Jalapa, Mex. 



12. carnicolor, Morr. (Cotyledon carnicolor, Baker). 

 Another somewhat similar species, but with only 6-8 

 fls. It is known only from garden specimens. 



13. maculata, Rose. This belongs also to this, alli- 

 ance, but grows at higher localities in Mex., and has 

 brighter green Ivs. It ought to live throughout the 

 year in our southern gardens. 



BB Fls. terminal, arranged in secund spikes or racemes, 



either simple or compound. 



c. Infl. a simple raceme. 



D. Plant hairy throughout. 



14. setosa, Rose & Purpus. Plants stemless, giving 

 out offsets from the base : Ivs. often 100 or more, form- 

 ing a dense, almost globular, rosette, thickish but 

 flattened, about 2 in. long, covered on both sides with 

 setiform hairs: infl. usually a simple secund raceme with 

 8-10 fls. ; petals red at base, yellow at tip, setose without. 

 Contr. Nat. Herb. 13: pi. 10. A very peculiar species, 

 recently collected by C. A. Purpus in Puebla, Mex. 



DD. Plant glabrous throughout. 

 E. The fls. sessile. 



15. Peacockii, Croucher (Cotyledon Peacockii, Baker). 

 Stemless: Ivs. about 50 in a close rosette, obovate, 

 spatulate, white-glaucous, slightly red toward the tip, 

 faintly keeled on the back: flowering branches form- 

 ing a scorpioid spike; corolla bright red, 6 Unes long. 

 It is doubtless of Mexican origin, although often 

 reported as from New Mex. or Calif. Page 870. 



EE. The fls. pedicelled. 

 F. Lower pedicels short. 



16. subsessilis, Rose. This is very similar to E. 

 Peacockii, but has shortly pedicelled fls. It is a very 

 beautiful species, well suited for flat bedding. Native 

 of Cent. Mex. 



FF. Lower pedicels elongated. 

 G. Lvs. very turgid. 



17. elegans. Rose. Stemless: Ivs. numerous, some- 

 times 80-100 in cult, specimens, forming very compact 

 rosettes, very glaucous, pale bluish green, very turgid, 

 with translucent margins, these sometimes reddish: 

 flowering branches pinkish, with 8-12 Ivs.; fls. in a 

 succulent raceme; corolla 5 lines long, its segms. dis- 

 tinct nearly to the base, pinkish with yellow spreading 

 tips. Known only from material collected near 

 Pachuca, Mex., by J. N. Rose. This is one of the most 

 beautiful species of the genus, and is well suited for 

 rockeries or for use in flat bedding. This is not to be 

 confused with Cotyledon elegans, N. E. Br., which is 

 Oliveranthus elegans. 



18. simulans, Rose. A similar species with somewhat 

 different habit and Ivs., and with slightly different 

 corolla; sepals appressed rather than spreading. 



GG. Lvs. not turgid. 

 H. The Ivs. glaucous green. 



19. glauca, Baker (Cotyledon glauca, Baker). Stem- 

 less: Ivs. in small but dense rosettes, nearly orbicular,
