In the "more advaiieed growth of the plants 

 they may be plaeed ahroail a few nionihs in the 

 .summer season, in such situations as are warm 

 and sheltered. 



These plants afford v.ariety among other stove 

 plants, and were formerly supposed to be the 

 tea-tree bv some.

 1X)1{0NICUM, a genus comprehending 

 plants of the hardy herbaceous perennial kind. 



Tt belongs to the class and order Si/iigc/w^ia 

 Polygamia Siipcr/lufr, and ranks in the natural 

 order of Compoiitie Discoidete. 



The eharactcrs are : that the ealyx is common, 

 with leaflets lanee-subulate, about twenty in num- 

 ber, equal, upright, of a double scries, length ge- 

 nerally of the rav of the corolla: the corolla com- 

 pound rayed : eorollules hermaphrodite tubular, 

 numerous, in the disk : females ligulate, of the 

 number of calvcular leaves, in the ray. Proper 

 of the hermaphrodite funnel-form ; border five- 

 cleft, patulous : female ligulate, lanceolate, three- 

 toothed : the stamina in the hermaphrodites 

 have five capillary filaments, very short : anther 

 cvlindric, tubular : the pistillum in the herma- 

 phrodites is an oblong germ: style lililbrui, 

 length of the stanii iis : stigma emarginatc : in 

 the females, gemi oblong: style filiform, length 

 of the hermaphrodite : stigmas two, refle.x : there 

 is no pericarpiuni : calvx slightly converging : 

 the seeds in the hermapiirodite solitary, obmate, 

 furrowed, a little compressed : down hairy: in 

 the females soliian', obovate, furrowed a little, 

 and compressed : down none : the receptacle is 

 naked and flat. 



The species are : ] . D. fiardfiliainhes, Great 

 Leopard's Bane ; 2. D. ptaiitagincinii, I'lantain- 

 Icaved Leopard's Banc ; 3. D. hiUidiuslruin, 

 Daisv-leavcd Leopard's Uane. 



The first has thick fle>hv roots, divided into 



many knots, sendins out strong lleshy fibres, 



which penetrate deep into the ground. The 



'root-leaves arc heart-shaped, hairy, pelioled: 



among these arise tlie flower-stalks, whiili are 



channelled .tnd hairy, mar three feet high, put- 

 tins out one or two smaller stalks from the side; 

 these iirow erect, and have one or two lieart- 

 shapecT leaves closely embracing the stalk ; this 

 and each braneli is terminated by one lariie yel- 

 low flower. It is a native of France, 8ic. flower- 

 ing in May. 



In the second species the leaves are indented 

 on their ediies towards their base; their upper 

 parts arc eiuire. The stalks rise about two teel 

 liish ; each is terminated by a large yellow flower, 

 like that of the first sort : they have two or 

 three alternate, embracing leaves, not so iiairy 

 as those of the first species. It is a native of 

 (Germany, iscc. flowering at the same time with 

 the lirst. 



Tlie third has also a perennial root. The 

 leaves are like those of the common daisy, but 

 longer, and not so broad. The flower grows on 

 a iKiked stalk near a foot long, and the root sel- 

 dom sends out more than one stalk. It is of a 

 white and yellow colour, and a native of the 

 Swiss Alps, flowering in A]>ril. 



Culture. — The methods of increasing the.sc 

 plants arc either by sow ing the seeds, or plant- 

 ing oflsets of their spreading roots, in the spring 

 or autumn, in shady spots of ground, either 

 where the plants are to remain, or, in the former 

 case, to be afterwards removed to them when 

 they have attained some inches growth. The, 

 last sort is best increased by parting the roots, 

 and succeeds most perfectly wheu the soil is 

 moist and the situation shady. 



All the sorts are well suited to the large bor- 

 ders, clumps, and other parts of extensive plea- 

 sure-grounds. 



DKACtENA, a genus containing plants of 

 the herbaceous and tree-like kind. 



It belongs to the class and order Hciandria 

 Moiiiigi/iiia, and ranka in the natural order of 

 Sarnii ntaccte. 



The characters are: that there is no calyx: 

 the corolla has six petals, oblong, somewhat up- 

 right, ccpial, cohering by the claws: the stamina 

 consist of SIX filaments, inserted into the claws, 

 subulate, thicker in the middle, membranace- 

 ous at the base, length seareclv of the corolla : 

 anthers oblong, incumbent : the pistillum is an 

 ovate aerm, six-striated: style filiform, Icngili 

 of the stamens: stigma three-cleft, obtuse: the 

 periearpium is an ~ovaie berry, six-furroweii, 

 three-celled : the seed* solitary, ovate-oblong, 

 ineurved at the tip. 



The species are : 1 . D. Dnuo, Dragon Tree ; 

 2. D. flrictt. Purple l>raea'na; 3. I). i-iiufolUi, 

 Sworci-leaved Drae:ena; 1. D. wiirg'innla. Aloe- 

 leaved Draea-na; 5. D. bwiul'is, ()\al leaved 

 Draeieiia.
