tliis climate, it is chiefly kept iu the stoves for 

 variety. 



Culture. — The propasiation in tliis tree is ef- 

 fected by sowing the seeds iu pots of h^'hl good 

 canh as soon as procured from abroad, i)hiiiiriiig 

 them in moderate hot-beds of dung or bark in 

 the stove, moderate waterings being given. 

 After the plants are risen a few inches, they 

 should be removed into separate small pots, and 

 replaced in the hot-beds, watering them as ne- 

 cessary. As thev advance in grow ih, they must 

 be removed into larsjer pots. 



It is a plant that deserves a place iu the stove, 

 tor its singularity and the beauty of its io- 

 liage. 



AKGE.MONK, a genus comprehending a 

 plant of the annual kind : The I'rickly I'oppv. 



It belongs to the class and order Poli/aiuliia 

 Monogynia, and ranks in the natural order of 

 Rhaaiiccs. 



The characters of which are : that the calvx 

 is a threc-kavvd, rouiulish perianth : tlie leaHcts 

 roundish w ith a point, concave aiul caducous : 

 the corolla consists of six roundish petals, from 

 erect spreading, larger than the calyx : the sta- 

 mina consist of numerous filiform tilaments, 

 the length of the calyx : the anthers are oblong 

 and erect : the pistiltum is an ovate, five-augled 

 germ : there is no stvlc : the stigma thiekish, 

 obtuse, reflex, quinquefid and permanent : the 

 pericarpium is an ovate, five-angled, one-celled, 

 Jialf-valved capsule : the seeds numerous and 

 very small : the receptacles linear, fastened to 

 the angles of the pericar|)ium, but not gaping: 

 the half-valved capsule distinguishes this from 

 the Paparcr. 



There is only one species cultivated in the 

 garden: A. ^lexicaim. 



It is an annual plant, rising to the height of 

 two or three feet, with stems armed with prickles : 

 leaves sinuate or jagged, soft, shining, stem- 

 clasping, the points of the jags ending in sharp 

 yellow spines ; on the upper side there are milky 

 veins, as in Our Ladv's Thistle ; on the under, 

 small prickles along the midrib and veins : the 

 flowers are solitary at the ends of the stem and 

 branches : the corolla is yellow, with from four 

 to six petals : the calyx consists of two or three 

 prickly leaves ; the stigma is capitate, Rmall, with 

 tive notches : the capsule superior, having live 

 or six ribs from top to bottom, and between the 

 ribs armed with bristle-shaped spines ; at the top 

 is the flatted stigma : the seeds are very nume- 

 rous, round, black, rough, with a compressed 

 .scar on one side : the valves of the capsule vary 

 in number, as well as the petals, from four to 

 six. It is a native of Mexico, and flovsers in 

 July and August. 



Citlliivt. — As this is an annu.il plant, it m.tv 

 be easily raised by sowinii the seeds iliinly in 

 sjjots of light canh in ilie j^Lues where the 

 plants are to remain. As the plants shed their 

 seeds, thev mosilv eonliiiue for sevcr.il vears af- 

 ter they have been once inlroiluecd. 



AKLST{)L(.)L'11IA, a genus eompreliindinn 

 various plains of the ln.rl)uctous and exotic

The characters are : tliat it has no calyx : the. 

 corolla is moiiopelalour, tubulous, irrejrular : 

 llie base swelling, subglohular, torulose : tlic 

 tube oblon<r, hexagon-eylindrie : limb dilated, 

 and extended htlow ii.io a long tongue; the 

 stamina have no lil.mients : the .inthero: six, 

 fastened at bottom to the stigmas, and four- 

 celled : the pisiillum is an oblong, inferior, an- 

 gular germ : style scarcely any : the stigma sub- 

 globular, six-parted, and concave : the pericar- 

 pium is a large, >ix-angkd, six-cilled cap^u!e : 

 the seeds several, depressed and incumbent : the 

 fruit varies in (isurc, being in some species 

 roundish, in others long. 



The species are numerous ; but those em- 

 ployed for ornaiiHnt in gardens are chiefly : \..i. 

 c-iicfa, I'pright Jjnthwort ; •2. A. Si/i/io, l?ruad- 

 leavcd I'irlhwort; 3. A. rtj/wwre;/?. Tree Hirth- 

 wort ; 4. A. semperrirani, I'lvergreen Hirtluvort ; 

 5. .-/. l)htoloAi'ia, Hamose-stalked ]5irtluvort. 



The first rises with an upright stalk to the 

 height of three feet : the leaves are long, nar- 

 row, hairv, growing close to the branches, 

 having scarce any foot-stalks : the flowers come 

 out singly from the axils, are near tour inches 

 long, of a dark purple colour, and grow erect ; 

 these are succeeded by slender vessels, about 

 one iueli long, lilled with flat heart-shapid 

 seeds. It is a native of N'era Cioiz in New 

 Spain.

 micylindric, grooved above, somewhat villose : 

 peduncles lateral, at the joints below the leaf, 

 pendulous, longer than the petiole, one or two
