1. cordifolia, Haw. (Megdsea cordifolia, Haw. Ber- 

 genia cordifolia, Sternb.) . Twelve to 20 in. high, robust : 

 Ivs. orbiculate-cordate, broad -and fleshy, margin undu- 

 late-serrate, glabrous, shining; petioles long and thick: 

 infl. a short, thick, angled, shiny scape: fls. clear rose, in 

 dense nodding cymes partly hidden in the Ivs. ; pedicels 

 short and thick; calyx-lobes short and broad; petals 

 roundish. March-May. Siberia. Gn.M.3:136. 

 Closely allied to S. crassifolia but differing in the 

 broader cordate-based Ivs. and in the rounder petals. 

 Var. alba, Hort. (Megdsea cordifolia yar. alba, Hort.). 

 Fls. delicate blush-pink, not true white. Var. grandi- 

 flora, Hort. Said to be unusually handsome in 

 If. and fl. Var. purpfcrea, Hort. (S. purpurea, Hort. 

 Megdsea cordifolia var. purpurea, Hort.). Lvs. smooth 

 and coarsely serrate, the panicles larger than the type 

 and carried well above the Ivs.: petals broad rounded 

 and deep reddish purple. Var. rdsea, Hort. (Megdsea 

 cordifolia var. rdsea, Hort.) has been offered. 



2. crassif dlia, Linn. (S. cuneifolia, Hort., not Linn. 

 S. sibirica, Hort., not Linn. Megdsea crassifolia, Haw. 

 Bergenia crassifolia, Fritsch). Fig. 3555. Six to 16 in. 

 high, stout: rhizomes woody: Ivs. obovate to long-obo- 

 vate, large and thick, narrowed at the base and decur- 

 rent on the petiole, margin serrate to nearly entire, 

 apex obtuse, glabrous, shining: infl. a fairly tall, angled, 

 reddish or purplish scape: fls. deep rose, lilac or pur- 

 plish, in dense panicles, elevated above the Ivs.; calyx- 

 lobes oblong, obtuse;

 is only a variation of 

 this species, with 

 lighter pink fls. Var. 

 orbicularis, Hort. (S. 



orbicularis, Hort. Bergenia orbicularis, Stein. Megdsea 

 orbicularis, Hort.). A small-growing form with broad 

 rather rounded Ivs., a branching habit and an abun- 

 dance of light rosy fls. which are borne well above 

 the foliage. 



3. purpurdscens, Hook. f. & Thorn. (Megdsea pur- 

 purascens, Hort. Bergenia purpurascens, Engl.). 

 Three to 12 in. high: Ivs. roundish-obovate to short- 

 oblong, 2-3 in. long, base somewhat cordate, margin 

 more or less undulate, glabrous: infl. a scape about 1 

 ft. high, purple, this and the pedicels very pubescent: 

 fls. deep purple, nodding, in few-fld. corymbose panicles; 

 calyx-lobes very obtuse; petals %in. long, obovate- 

 oblong, sometimes long-clawed: fr. elliptic-lanceolate,

 5066. H.F. II. 1:172. B.H. 9:1. F.S. 14:1401. A 

 very handsome species because of its purple scapes and 

 fls. and the beautiful purple-and-crimson autumnal 

 foliage. Succeeds best in a rather sheltered spot. 



4. ligulata, Wall. (Megdsea ligulata, Hort. Bergenia 

 ligulata, Engl.). One foot high, stout: radical Ivs. large, 

 orbicular or obovate, 2-12 in. diam., base cordate, mar- 



3555. Saxifraga crassifolia. 



gins entire but ciliate, both surfaces glabrous: infl. an 

 erect naked scape, this and the pedicels and calyx gla- 

 brous: fls. white, rose or purplish, campanulate in nod- 

 ding 1-sided racemes; calyx-lobes ovate, not narrowed 

 at base; petals J^-l in. long, orbicular and clawed: fr. 

 subglobose, cernuous. March-May. Himalayan region. 

 B.M. 3046 ("the sepals too acute and the leaves too 

 undulate," according to Hooker). L.B.C. 8:747 RH 

 1868:270. J.H. III. 69:136. Gn. 62, p. 25; 76, p. 204. 

 Not perfectly hardy at Boston. Sometimes erro- 

 neously written S. lingulata which is a very different 

 species (No. 67). S. orndta, Decne. (Bergenia orndta, 

 Stein), is said to have large coriaceous, persistent Ivs., 

 fleshy sts., and large rose fls. in cymes. Apparently 

 does not possess any character to distinguish it from S. 

 ligulata except the fls. are a shade lighter in color. Var. 

 ciliata, Hook. (S. ciliata, Royle. S. thysanodes, Lindl. 

 S. Stracheyi var. thysanodes, Hort. Megdsea ciliata, 

 Haw. M. ligulata var. ciliata, Hort. Bergenia ciliata, 

 Stein). Lvs. hirsute on both surfaces, margins strongly 

 ciliate. B.M. 4915. B.R. 32:33 (as S. thysanodes). 

 G.C. III. 5:365. F.E. 16:472. Var. Leichtlinii, Hort. 

 (S.Leichtlinii,HoTt. Megdsea Leichtlinii, Hort.). Grows 

 about 1 ft. high and has large crimson Ivs. and rose- 

 colored fls. Var. rdsea, Hort., is a form with rose- 

 colored fls. Var. rftbra, Hort., is an early-flowering, low 

 form with red or red-purple fls. Var. speciosa, Hort. 

 (S. speciosa, Hort., not Doerfl. & Hayek. Megdsea 

 speciosa, Hort.). Lvs. broadly ovate/ leathery : fls. 

 crimson or deep rosy crimson. Gn. 71, p. 250. J.H. III. 

 60:393. By some this is thought to be a garden hybrid 

 . S. ligulata x S. crassifolia. 



5. Stracheyi, Hook. f. & Thom. (S.unguiculdta, Hort., 

 not Engl. Megdsea Stracheyi, Hort. Bergenia Stracheyi, 

 Stein). Fig. 3556. Six inches to 1 ft. or more high: Ivs. 

 obovate, usually not cordate at base, margin subentire, 

 ciliate or crenate-serrate, both surfaces glabrous: infl. 

 a scape about 1 ft. high with the pedicels and calyx 

 pubescent or puberulous: fls. blush-pink to rose (some- 

 times yellow), in broad branching panicles %-l in. 

 diam.; calyx-lobes oblong. March. Kashmir, 8.000- 

 14,000 ft. B.M. 5967(?). G.M. 39:233. J.H. III. 

 32:281. G. 12:337. More hardy than S. ligulata.

 Mllesii, Hort. Leicht. Bergenia Milesii, Stein. Megdsea 

 Stracheyi var. Mllesii, Hort.). Differs from the type in 

 having longer Ivs. (9-12 x 4-5 in. at the middle) : fls. 

 white; petals distinctly clawed. March. Himalaya. 

 Var. Schmidtii, Hubb. (S. thysanodes, Hort. Haage 

 & Schmidt, not Lindl. S. Schmidtii, Regel. Bergenia 

 Schmidtii, Hort.). Lvs. ovate, base equally rotundate 

 or attenuate to the petiole, margin coarsely crenate 

 and then dentate, the teeth cuspidate-ciliate : fls. pani- 

 cled, similar to those of S. crassifolia. Himalaya . Gt. 

 27:946. B.R. 29:65 (as S. ciliata). 



Section II. CTMBALARIA. 



A. Lower Ivs. 7-11-lobed; the lobes acute.. 6. Cymbalaria

very shortly apiculate 7. Huetiana 



6. Cymbalaria, Linn. Annual or biennial: sts.

 faces, margin glandular-pilose; lower Ivs. reniform, 

 cordate or truncate at base, 7-11-lobed, lobes broad- 

 acute; upper Ivs. short-petioled, 3-7-lobed, base atten- 

 uate: infl. cymose with elongated axis; pedicels long,
