KEY TO SECTION'S. 



A. Outer bracts developed, reaching at least half-way 

 up the calyx, often equaling or even exceeding it. 

 B. Annulus or ring at base of corolla absent; 

 corolla-tube mostly exserted; anther-cells^ 

 parallel. Section I. BETONICA. Species 1-5. 



BB. Annulus or nng at base of corolla oblique and 

 hairy; corolla-tube usually inclosed; anther- 

 cells divergent or divaricate. 



Section II. ERIOSTOMTTM. Species 6-10. 

 AA. Outer bracts minute, very much shorter than the 



calyx. Section III. EUSTACHYS. Species 11-17. 



Section I. BETONICA. 



A. Lowest floral-hs. cordate-ovate. 



B. Corolla, more than 1 in. long 3. grandiflora 



BB. Corolla scarcely %in. long 1. densiflora 



AA. Lowest floral hs. lanceolate. 



B. Lrs. white beneath 5. discolor 



BB. Lrs. green or pale beneath. 



c. Calyx y<iin. or more long 4. longifolia 



cc. Calyx scarcely %in. long 2. officinalis 



1. densiflora, Benth. (Betoniea incana, Ait.). Peren- 

 nial, l/^ ft. high: sts. erect, hirsute: Ivs. 2-3 in. long, 

 petioled, ovate-oblong, obtuse, crenate, base cordate, 

 soft-pilose or more or less villous; floral Ivs., lowest cor- 

 date-ovate, short -petioled: floral whorls approximate 

 in a dense spike, lower whorls remote: calyx campanu- 

 late ; corolla villous outside, flesh-colored. S. Eu. B.M. 

 2125. There are older names referred to this species, 

 but it is not certain that they are truly synonyms; even 

 Betoniea incana may not belong here. 



2. officinalis, Franch. (S. Betoniea, Benth. Betoniea 

 officinalis, Linn.). BETONT. Fig. 3671. A hardy per- 

 ennial herb 1-3 ft. high: lower Ivs. long-pet ioled, ovate- 

 oblong, crenate, obtuse, cordate at the base, 



3-6 in. long; upper Ivs. distant, sessile, 

 oblong -lanceolate, acute: fls. purple, in a 

 dense, terminal spike. July. Eu., Asia Minor. 

 Rarely found as an escape in this country, 

 and once cult, for use in domestic medicine. 

 Useful for ornament, and now advertised for 

 that purpose. There are white-fld. forms of 

 the species offered in the trade under the 

 names of S. Betoniea alba and S. Betoniea 

 albiflora and there is also a large-fld. form 

 with soft rose-colored fls. known as S. Betoniea 

 grandiflora. 



3. grandiflSra, Benth. (Belonica rosea, Hort. 

 B. spicata, Hort. B. grandiflora, Willd.). A 

 hardy perennial about 1 ft. high: lower Ivs. 

 broadly ovate, obtuse-crenate, long-pet ioled, 

 base broadly heart-shaped; the upper gradu- 

 ally smaller, nearly similar and sessile, the 

 uppermost bract-like: fls. violet, large and 

 showy, the curving tube about 1 in. long and 

 3 or 4 times surpassing the calyx, in 2-3 dis- 

 tinct whorls of 10-20 fls. each. Asia Minor, 

 etc. B.M. 700. G.M. 53:628. Var. robusta, 

 Hort. (Belonica grandiflora robusta, Hort. B. 

 spicata robu-sta, Hort.), is said to have tufts 

 of corrugated Ivs., to grow 18 in. high and 



spikes 3 in. long of rosy pink fls. Gn.W. 25: 3671 



204 



299. Var. superba, Hort. (Betoniea grandiflora superba, 

 Hort. B. superba, Hort.), is said to have showy spikes 

 of intense mauve or a rich shade of purple-violet fls. 

 There is a white variant of this known in the trade as 

 Betoniea superba alba. 



4. longiffilia, Benth. (Betoniea orienialis, Linn.). A 

 hardy perennial herb about 1 ft. high, densely villous: 

 lower Ivs. petioled, oblong-lanceolate, obtuse, crenate, 

 deeply cordate at the base, 4-6 in. long; the upper Ivs. 

 similar in shape but sessile, those of the infl. bract-like: 

 fls. reddish purple to pink, in a cylindrical, somewhat 

 interrupted spike about %ft. long. July. Caucasus. 

 Briquet in Engler & PrantFs Pflanzenfamilien has 

 adopted macrostachys as the specific name, basing his 

 name on Betoniea macrostachys, Wender, but authori- 

 ties differ as to the identity of Wender's material, hence 

 the Bentham name has been retained. 



5. discolor, Benth. (S. nivea, Benth., not Labill. 

 Betoniea nivea, Stev.). Perennial, about 1 ft. high, vil- 

 lous: Ivs. petiolate, oblong-lanceolate, obtuse, deeply 

 crenate, rugose above, white-lanate beneath; floral Ivs., 

 upper lanceolate: floral whorls many-fld., somewhat dis- 

 tinct, few: calyx lanugmose-villous; corolla large, vil- 

 lous, rose, rarely yellowish white. Caucasus.

c. LTS. green on both 



surfaces 9. alpina 



cc. Lvs. green above, canes-

6. tmolea, Boiss. Perennial, about 

 1 ft. high: sts. ascending, densely serice- 

 ous-pannose: Ivs. lanceolate or oblong- 

 lanceolate, obtuse, obscurely dentate, 

 petioled, the radical about 3 in. long; 

 floral Ivs. oblong, acuminate: floral 

 whorls densely many-fld., far remote: 

 calyx pedicellate, hirsute, long-cam- 

 panulate; corolla yellow, tube included. 

 Mt. Tmolus region, Asia Minor. 



7. germanica, Linn. Perennial, 1-4 

 ft. high: sts. herbaceous, tall, loosely 

 white-lanate: radical Ivs. 2-5 in. long, 

 rather long-petiqled; cauline Ivs. short- 



petioled, ovate or ovate- 

 lanceolate, obtuse, base 

 usually cordate, crenate; 

 lower floral Ivs. subsessile, 

 somewhat clasping, cre- 

 nate, white-lanate: floral 

 whorls many-fld., distinct, 

 racemose, upper approxi- 

 mate: calyx lanate inside; 

 corolla pale pink, varie- 

 gated with white, lanate 

 outside, tube included. 

 Eu., Cent. Asia and N. 

 Afr. B.R. 1289. Var. Bois- 

 sieri, Briq. (S. cretica,

 late floral Ivs. and a rose- 

 colored corolla, the upper 

 lip of which is lanate. S.E.
