42. arvernense 



43. Boutigny- 



[anum 



44. alpinum 



45. Boissieri 



1. poculiforme, Berger & DeWild. St. simple, erect, 

 more or less elongated: basal Ivs. in a rosette, oblong- 

 lanceolate, cuneate at the apex, serrate-ciliate, other- 

 wise glabrous; cauline Ivs. obovate-spatulate: fls. 9- 

 merous, in a glabrous panicle; calyx glabrous, segms. 

 lanceolate-triangular subacute; petals lanceolate, acute. 

 Canary Isls.(?). 



2. canariense, Linn. Subshrub: st. short, thick: Ivs. 

 in a flattened rosette, obovate-spatulate, mucronate, 

 attenuate to a petiole, villous; cauline Ivs. obovate- 

 rotundate: fls. 7-9-merous, pale yellow or whitish, in a 

 lax thyrsoid elongated panicle; calyx very villous, segms. 

 ovate-lanceolate; petals linear, acute. Canary Isls. 



3. arbdreum, Linn. St. arborescent, with terete 

 branches: rosettes concave: Ivs. spreading, obovate- 

 spatulate, obtuse, mucronate, base cuneate, rather gla- 

 brous: fls. golden yellow in a many-fld. leafy panicle; 

 calyx-segms. ovate, rather acute; petals spreading, 10-12, 

 elliptical. Medit. region. 



4. chrysanthum, Hqchst. Subshrub, 1-2 ft. high: st. 

 thick: Ivs. pectinate-ciliate, on barren shoots rosulate, 

 roundish ovate; cauline Ivs. obovate-oblong, rounded 

 above, apiculate: fls. about 8-merous, yellow, or 

 white (?), in a thyrsoid corymb; calyx-segms. short- 

 triangular; petals linear - lanceolate. Abyssinia. 

 Closely allied to S. arboreum and possibly not distinct 

 from it. 



5. tabulaeffirme, Haw. Shrubby: sts. erect-branched: 

 Ivs. oblong-spatulate, base attenuate, flat, ciliate, 

 gathered at the tips of the branches in a flat rosette: 

 peduncles minutely glandular: petals linear-lanceolate, 

 very pale sulfur. Canary Isls. 



6. spathulatum, Hornem. (S. barbdtum, C. Smith. 

 Mbnium barbdtum, Webb & Berth.). Shrubby: sts. 

 stout; branches horizontal near the st., then arched and 

 erect : rosettes flat, not dense: Ivs. of the rosettes oblong- 

 spatulate, acute, margin papillose, both surfaces with 

 linear, red-brown markings; cauline Ivs. linear-lanceo- 

 late, acuminate: fls. 8-10-merous, in rather open 

 panicles, the fls. on the upper side of the branches; 

 calyx-segms. deltoid; petals oblong-lanceolate, acute. 

 Canary Isls. Some of the material grown under this 

 name is certainly not the species above described, but 

 probably a form of S. tectorum. 



7. He&ffelii, Schott (S. pdtens, Griseb. & Schenk). 

 Barren rosette lJ^-2 in. diam., the young rosettes not 

 peduncled : Ivs. 30-40 to a rosette, obovate-cuneate, dis- 

 tinctly cuspidate, glabrous, lower part pale green, upper 

 third or even half tinted bright red-brown, margin 

 crowded, stiff, white-ciliate, outer Ivs. %-l x %in.;
