STACHYS 



8. lanata, Jacq. WOOLLY WOUNDWORT. A hardy 

 perennial 1-1 Yi ft. high, white-woolly throughout: Ivs. 

 oblong-elliptical, the upper smaller, the uppermost 

 much shorter and whorled: fls. small, purple, in dense 

 30- or more-fld. whorls in interrupted spikes. Caucasus 

 to Persia. Gn. 78, p. 543. Often grown as a bedding 

 plant. Valuable for its very white herbage.

9. alpina, Linn. Herbaceous, tall : sts. erect, pilosely 

 somewhat lanate: Ivs. petioled, ovate, serrate-crenate, 

 base cordate, both surfaces green or slightly canes- 

 cent beneath; floral Ivs. narrower, gradually smaller: 

 floral whorls all remote, 15-20-fld.: calyx rather 

 pilose, teeth lanceolate-ovate, strongly spined; corolla 

 obscurely purplish or red-brownish, about twice as long 

 as the calyx. Eu. 



10. sericea, Wall. Herbaceous, tall: st. erect, very 

 pilose: Ivs. petioled, ovate or ovate-oblong, rather 

 obtuse, crenate, base cordate, both surfaces villous, 

 green above, pale or hoary beneath, the younger Ivs. 

 sericeous-lanate: floral whorls all distant, 10-15-fld.: 

 calyx lanate, teeth ovate-lanceolate, very acute, spined; 

 corolla pink, spotted with purple, hairy, scarcely 

 longer than the calyx. Himalaya region and N. Asia. 

 There is an older S. sericea (of Cavanilles), but its 

 botanical status is unknown. It is a native of Chile.

AA. Species perennial. 



B. Corolla-tube long-exserted 11. coccinea 



BB. Corolla-tube included in the calyx or 



slightly exserted. 

 c. Plant with a basal rosette, below 



which thefloweiing shoots arise... 16. citrina 

 cc. Plant without a basal rosette. 



D. Angles of sts. not retrorse-hairy

 prickly, rarely glabrous: an- 

 nulus inside corolla, pilose, 

 complete.

BE. Tubers present. 



F. Lvs. ovate, deltoid-ovate or 

 ovate-lanceolate: tubers 

 slender, clavate, nodose. . . 12. Sieboldii 

 FF. Lvs. cordate-oblong-lanceo- 

 late, very obtuse: tubers 

 cylindrical, uniformly 

 nodose 14. floridana 



Subsection CALOSTACHYDES. 



11. coccinea, Jacq. One to 2 ft., slender, soft-pubes- 

 cent: Ivs. ovate-lanceolate, cordate at base or somewhat 

 deltoid, obtuse, crenate: fls. scarlet-red, the narrow tube 

 much exceeding the calyx, pedicelled, in an interrupted 

 spike, blooming in succession. W. Texas to Ariz. B.M. 

 666. P.M. 8:101. Showy. 



Subsection GENUINE. 



12. Sieboldii, Miq. (S. affinis, Bunge, not Fresenius. 

 S. tuberifera, Naudin). CHOROGI. CHINESE or JAPA- 

 NESE ARTICHOKE. KNOTROOT. CROSNES DU JAPAN. 

 Fig. 3672. Erect hairy mint-like plant, growing 

 10-18 in. tall: Ivs. ovate to deltoid-ovate to ovate- 

 lanceolate, cordate at base, obtuse-dentate, stalked: fls. 

 small, whitish or light red, in a small spike: 

 tubers (Fig. 3672) 2-3 in. long, slender, nodose, 

 white, produced in great numbers just under 

 the surface of the ground. China, Japan. G.C. 

 III. 3:13. Sent to France in 1882 from Pekin 

 by Dr. Bretschneider, and about ten years ago 

 intro. into this country. It is cult, for the crisp 

 tubers, which may be eaten either raw or cooked. 

 These tubers soon shrivel and lose their value if 

 exposed to the air. The tubers withstand the 

 ^winter in Cent. N. Y. without protection, so 

 that a well-established plant takes care of itself 

 and spreads. For history, chemical analyses, etc., 

 see Cornell Bull. No. 37. 



13. aspera, Michx. Erect, usually strict, 3-4 

 ft. high, the st. retrorsely hairy on the angles: 

 Ivs. oblong-ovate to oblong-lanceolate, mostly acumi- 

 nate, serrate, petiolate: corolla small, glabrous, pale red 

 or purple, in an interrupted spike. Wet places, Ont. 

 and Minn, to the Gulf. L.B.C. 15:1412. Has been 

 offered by dealers in native plants. 



14. floridana, Shuttlew. Slender, erect, 1-2 ft., 

 branching, glabrous: Ivs. cordate-oblong-lanceolate, 

 blunt-toothed, stalked: fls. small, light red, in an open 

 interrupted spike: tubers cylindrical, uniformly nodose. 

 4-6 in. long. Fla. Has been tested abroad as a food 

 plant, and also at the Cornell Exp. Sta. (see Bull. 

 No. 61), but practically unknown horticulturally. The 

 tubers are as good for eating as those of S. Sieboldii.

 petioled, oblong-ovate or lanceolate, obtuse, crenate, 

 \-\Y% in. long, base rounded or narrowed, rugose, 

 hairy; floral Ivs. sessile: floral whorls about 10-fld., dis- 

 tant : calyx ovate-campanulate, hairy, teeth ovate, sub- 

 spinose; corolla yellowish white, throat purplish, gla- 

 brous, twice as long as the calyx. S. Eu., Caucasus.

 linear: calyx somewhat scabrous, teeth as long as the 

 tube. Caucasus.

 terminal heads which 

 are short-ovate, dense,
