Chimborazo Gentian. PI. dwarf. 



j- f The following plants hare been described as species of 

 Gentiana by various authors , but none of them are legitimate 

 species of that genus. 



40 G. ? DC'BIA (Thunb. prod. 1. p. 48. fl. cap. 2. p. 174.) 

 fructiferous stem terete, leafless, or the leaves fall off early, they 

 are therefore unknown ; panicles terminal, trichotomous, supra- 

 decompound ; corolla 4-cleft. Native of the Cape of Good 

 Hope. Stem simple, erect. Calyx 4-parted; with small, acute 

 segments. Corolla 4-parted, purple ; segments acute. Cap- 

 sule oblong, ending in 4 points. Styles 2, divisible.

 very narrow linear leaves, and slender branched stems ; flowers 

 terminal, cymose ; corolla funnel-shaped, 4~cleft ; limb rather

 no. 5 1 . Plant becoming black on drying. Stem dichotomously 

 branched at top. Leaves capillary : lower ones nearly an inch

 species of Houslunia. 



Blackish Gentian. PI. | foot. 



42 G. ? CALTciXA (Lam. diet. 2. p. 639.) stem articulated, di- 

 chotomously panicled, and rather angular at top ; leaves ovate- 

 oblong: lower ones obtuse: the rest acute; flowers solitary, 

 terminal, on long peduncles ; corolla deeply 5-6-cleft, hardly 

 exceeding the calyx, which is large and 5-6-parted. Native of 

 Louisiana, ex herb. Juss. Flowers yellowish. Calycine seg- 

 ments linear, acute, rather unequal. Corolla rotate, with oblong 

 obtuse segments. Stamens free. Stigmas oblong, large ; style

43 G. ? MITZNOFA'NA (Roem. et Schultes, syst. 6. p. 18C.) 

 stem erect, terete, simple ; leaves sessile, cordate-ovate, acute, 

 7 -nerved : floral ones the narrowest ; flowers terminal, twin, 

 erect ; calycine segments acute, length of the tube of the corolla. 

 Native of Japan, in boggy places. Planta Japanensis, Mitz- 

 nofana, i. e. flos aquaticus, Clever, in misc. nat. cur. dec. 2. 

 ann. 8. p. 489. f. 51. 2 icones. * Frcel. gent. p. 119. Habit 

 altogether different from Gentiana. Root fibry. Corolla with 

 a grey tube, blue limb, and obtuse segments. 



Mitznofana Gentian. PI. ^ foot. 



44 G. ? SCILLOIDES (Lin. suppl. 1. p. 175.) stem 1-flowered, 

 prostrate ; leaves obovate, obtuse, 3-nerved ; corolla funnel- 

 shaped, 5-cleft; bracteas twin. Native of the Azores, Masson, 

 Hfppion scilloides, Schmidt. Leaves on short petioles : the 

 upper ones more remote. Peduncles long, naked, terminal, 1- 

 flowered. Bracteas opposite, subulate, erect, beneath the flowers. 

 Calycine segments linear. Tube of corolla funnel-shaped, 

 longer than the calyx ; limb 5-cleft, flat, beardless, yellow. This 

 plant does not probably belong to the genus, from the form of 

 the calyx and corolla; but nothing is said of the style by 

 Linnaeus. Perhaps a genus of Campanulaceae. 



Scillu-like Gentian. PI. 1 foot, prostrate. 



t 1 1 If hat are the following species ? 



1 Gentiana major Mariana, angustiori folio Gentiariella? 

 vernae, floribus cosruleis plurimis in summitate congestis. Pluk. 

 mant. 89. Perhaps Gentiana cruciata. 



2 Gentiana angustifolia Americana, flore ex ochro cyaneo 

 mixto in fastigio caulis unico. Plukn. mant. 89. Ray. suppl. 

 p. 370. no. 4. 



3 Gentiana orientalis, amplissimo et acutissimo asclepiadis 

 folio. Tourn. cor. 2. Said by Cham, in Linnaea. 1. p. 175. to 

 be the same as Gentiana septemflda. 



4 Gentiana orientalis, foliis venosis, flore magno candidissimo, 

 Tourn. cor. 2. var. flore exalbo-virescente. Tourn. 1. c. Said 

 by Cham, in Linnaea. 1. p. 174. to be the same as Gentiana 

 gelida. 



5 Gentiana orientalis, minor autumnalis myrtifolia flore mag- 

 no coeruleo, Tourn. cor. 2. Said by Cham, in Linnaea. 1. p. 

 175. to be Gentiana septemfida. 



6 Gentiana rivularis and Gentiana pallens, Thunb. mus. 

 nat. acad. ups. 11. p. 180. are probably a species of Sebt&a. 



Cult. The South American and New Zealand species of 

 Gentian should be grown in pots, well drained with sherds, in a 

 mixture of peat and sand, and placed among other alpine 

 plants. They will require protection in winter. The seeds of 

 annual kinds may be sown in pots, in the same kind of soil, or 

 even in the open border. Gentiana macrophyUa, the only 

 hardy perennial, is well fitted for a border flower, but grows 

 best in a peat soil. All the perennial species are either to be 

 increased by dividing at the root, or by seed.
