GENTIANA 



GENTIANA 



43. Gaudiniana, Thorn. Natural hybrid with the 

 habit of G. purpurea, but the membranous corolla of G. 

 punctata: fls. rosy violet. Eu., but not widely cult. 



44. macrophylla, Pall. Perennial, with erect or ascend- 

 ing St.: Ivs. lanceolate, distant, very spreading, 3- 

 nerved, the upper often connate-perfoliate; internodes 

 unequal: fls. dark blue. July, Aug. B.M. 1414, not 

 L.B.C. 3:218. N. Eu. and Asia. Cult, like G. lutea. 



45. Cruciata, Linn. (Crucidta verticilldta, Gilib.). An 

 erect and leafy perennial: Ivs. ovate-lanceolate, 

 crowded, erect-spreading, the upper connate-perf oliate ; 

 internodes equal: fls. axillary, in sparse clusters, dark 

 blue. June-Aug. Eu., N. Asia. Cult, like G. lutea. 

 Prefers limestone and full sunlight. 



46. carpatica, Kit. (Probably G. nivdlis, Linn.). A 

 slender perennial with small obovate Ivs.: fls. solitary, 

 axillary or terminal, dark blue (as are the next 4 spe- 

 cies); corolla funnel-shaped, scarcely exceeding %in. 

 long. Carpathian Mts. Little known. 



47. imbricata, Froel. Lvs. acute, margins scabrous, 

 (the next 3 species with smooth margins) : corolla-lobes 

 subrotund. June, July. Limestone rocks, Alps. In 

 this and the next 3 species, the corolla-lobes are usually 

 crenate, half the length of the tube, and 6 times the 

 length of the plaits. "Eastern and granitic Alps." 

 Correvon. Cult, like G. bavarica. 



48. verna, Linn. Fig. 1627. Tufted: st. angled: Ivs. 

 ovate or ovate-lanceolate : fls. solitary; calyx membran- 

 aceous; corolla nearly bowl-shaped; lobes ovate, obtuse. 

 Apr.-June. Eu., Caucasus. B.M. 491. L.B.C. 1:62. 

 R.H. 1859, p. 250. Gn. 48, p. 139; 75, p. 284. 

 G.C. II. 24:373. J.H. III. 52:58. G.W. 23:431. Var. 

 alata, Griseb. (G. angulbsa, Bieb.), is taller and has the 

 nerves of the ventricose calyx produced into wings. 

 Rockwork, in a compost of heath-soil, finely crushed 

 granite, and vegetable-mold, with full sunlight. A 

 supposed hybrid between this and the following has 

 been described as G. Favrdtii, Hort. The plant is 

 practically unknown in Amer. 



49. bavSrica, Linn. Calyx-lobes lanceolate; corolla 

 funnel- or nearly bowl-shaped; lobes obovate, obtuse; 

 ovary sessile: seeds not winged. May-Aug. Cent. Eu. 

 F.S. 7:651. L.B.C. 13:1256. J.H. III. 35:585. Gn. 

 15:278 (poor). The pictures cited all show a salver- 

 shaped corolla. "Requires a soil that is peaty, or at the 

 very least porous and cool, well drained, and capable of 

 retaining an abundant supply of moisture, although it 



may be fully ex- 

 posed to the sun. 

 In the alpine 

 garden here we 

 grow them in 

 pure sphagnum 

 moss on a wall 

 facing due south, 

 but the plants 

 which we raise 

 for sale are grown 

 in pots in a com- 

 post of sphag- 

 num, heath -soil 

 and sand. Finest 

 of Group III." 

 Correvon. 



1627. Gentiana verna. ( X %) 50. pftmila, 



Jacq. A tiny 



almost moss-like gentian with a 3-4-angled st.: Ivs. 

 clustered, scarcely more than J^in. long: fls. solitary 

 terminal; calyx-lobes linear; corolla deep blue, the lobes 

 ovate, acute. June, July. Tyrolese and Carinthian Alps. 



51. acaulis, Linn. (G. exdsa, Presl.). GENTIANELLA. 

 STEMLESS GENTIAN. Fig. 1628. By the botanists of 

 continental Eu. this is often split up into the 4 or 5 

 following species. The plants that Linnaeus had in 



mind were probably mostly G. Clusii and G. Kochiana. 

 For pictures of G. acaulis in its widest sense, see B. M. 

 52. G.C. III. 15:236. G.W. 3, p. 289. J.H. III. 52:59. 

 R.B. 28:204. Gn. 48, p. 146; 54, p. 39. F.S. 23:2421, 

 where a more detailed account of the 4 following species 



1628. Gentiana acaulis. 



is given. A var. Kochii, Hort., is known but it may 

 well be G. Kochiana. A white-fld. form, var. alba, is 

 advertised. 



52. angustifdlia, Vill., not Michx. Stoloniferous: 

 Ivs. linear-oblong, narrowing toward the base, 

 glistening above: fls. spotted with sprightly green; 

 calyx-lobes more or less spreading, oval, abruptly con- 

 tracted at the base. May, June. Limestone rocks, 

 Alps. Considered by Correvon the handsomest spe- 

 cies of the whole genus. 



53. Kochiana, Perr. & Song. Lvs. large, flat, thin, 

 spreading, oval or broadly oblong, light green: calyx- 

 lobes oblong, limp, more or less contracted at the base 

 and separated by truncate sinuses; corolla with 5 black- 

 ish green spots on the throat. May, June. Common in 

 pastures on granitic Alps. Dislikes lime. It seems 

 almost certain that this is the G. acaulis var. Kochii of 

 many gardeners. 



54. Clftsii, Perr. & Song. A low acaulescent peren- 

 nial perhaps not different from G. acaulis and so con- 

 sidered in "Index Kewensis:" Ivs. lanceolate-acute, 

 leathery: fls. dark blue; calyx-lobes pressed close 

 against corolla, not contracted at base, and separated 

 by acute sinuses. May, June. Limestone rocks, Alps. 



55. alpina, Vill. St. almost wanting: Ivs. small, 

 glistening, curving inward and imbricated, forming 

 rosettes which incurve at about the middle: fls. dark 

 blue. May, June. Granitic Alps. This and G. Kochi- 

 ana "require a compost of one-third crushed granite, 

 one-third heath soil, and one-third vegetable loam, and 

 should be planted on rockwork half exposed to the sun." 



56. dinarica, Beck. Lvs. broad, thick, erect: fls. 

 dark blue. Certainly a mere form of G. acaulis, but 

 described as differing from that species in having no 

 spots on the corolla. Alps of S. and E. Austria. 



The following are names of gentians not sufficiently described 

 for insertion above or as yet scarcely known in cult. : G. arverntnsis, 

 Hort. Perhaps a var. of G. Pneumonanthe. Fls. Napoleon blue. 

 See G.C. II. 20:40, desc. G. 29:7. G. Charpentieri, Thorn. Natural 

 hybrid, intermediate between G. lutea and G. punctata: corolla 

 spotted red; calyx 5-cut. Grisebach does not say whether the 

 corolla is not plaited, anthers always free, and style none. Alps, 

 above Engadine. G. corymbifera, Hort., is described as 12-18 in. 

 high, with usually simple sts. branching toward the top: fls. white, 

 about 1 in. diam. New Zeal. G.C. III. 46:203. G. Fetisdwii, Regel. 

 St. erect, tall: fls. deep blue. China. Gt. 31:1069. G. Hsengsiii, 

 Hausm.=G. Kummeriana. G. Kesselringii, Regel. Height about 

 8 in.: fls. whitish, dotted violet outside. Turkestan. Gt. 31:1087. 

 G. Kummeriana, Sendt. Hybrid between G. lutea and G. Pannonica. 

 Fls. yellowish. G. L&wrencei, Burkill. Allied to G. ornata but dis- 

 tinguished by the much longer linear Ivs. : corolla about 1 % i n 

 long, blue above, the tube paler with dark blue lines. Mongolia. 

 G.C. III. 38:307. G. Wallichiana. Height 8-12 in.: fls. clear blue. 

 G. Walujewi, Regel & Schmalh. Fls. whitish, dotted pale blue. 

 Turkestan. Gt. 33:1140. WlLHELM MlLLER.
