seeds or more in each, about an inch and half 

 deep: when the plants are come up, they should 

 he thinned out to one or two of the strongest. 

 But to have the plants more forward, so as to 

 produce ripe seed-spikes more eflectu.slly, some 

 should be sown in a hot-bed at the same time, 

 and when the plants are three or four inches 

 high, he forwarded by pricking them out upon 

 another hot-bed, cither under a deep frame or 

 an awning of hoop arches to be covered with 

 mats occasionall-y, allowing them plenty of free 

 air; and when they have sufficient growth, as 

 in May, they may be transplanted, with balls 

 of earth about their roots, inio the full ground 

 in the borders or shrubbery clumps, in warm 

 sunny situations, being well watered; and when 

 the summer proves warm and dry, they often 

 produce perfect heads, and the seeds ripen in a 

 good manner. 



As the plants mostly nui up in tall stalks, it 

 is proper to support each with a tall neat stake, 

 especially where much exposed to wind and 

 rain. 



These plants in the different varieties have a 

 fine effect in the back parts of borders, clumpj, 

 and other places, in warm sheltered situaiions. 



ZINNfA, a oenus containing plants of the 

 annual flowering kind. 



It belonirs to the class and order S!/7?gcnesia 

 Puli/irumia Sii/)fi;fiiia. 



The characters are : that the calvx has the 

 general cup oval, cvlindric, and imbricated, 

 with many bluni, upright, persistent scales: the 

 corolla compound and radiated, consisting of 

 hermaphrodite florets, placed in the disk, and 

 female ones, which are lisrulated, and form the 

 ravs : the stamina of the hermaphrodites are 

 five short filaments, with cylindric lubulose 

 antherae : the pistilluni is an oblong aristated 

 germ, with a slender seniibifid style, and two 

 erect obtuse stigma''.: in the female flowers the 

 sermen is oblong and triquetrous, with a capil- 

 lary style, and two recurved stigmas : the peri- 

 carpium has the calvx containing oblong solitary 

 seeds crowned with down, and placed on a pa- 

 leaceous receptacle. 



The species cultivated are: 1. Z. patic'ijhra, 

 Few-flowered Yellow Zinnia; 2. Z. muuiflora. 

 Many-flowered Red Zinnia. 



The first has the root fibrous, from which 

 arises the stalk to abo-it I'lio feet high ; it is 

 woody below, and branches upwards, which are 

 placed opjjosile : the^e arc furnished with oblong 

 leaves of a pleasing green colour : the flowers 

 terminate the ends of the branches on long foot- 

 stalks ; they arc of a yellow colour, whieh 

 decays before the seeds are ripe. It is an an- 

 nual. 



The second species is also annual : th? sLilk 

 rises erect with upright branches ; these are 

 channelled and hairy : the leaves are oval, lan- 

 ceolate, and placed opposite : the flowers come 

 out at the extreme part of the branches : the 

 florets of the disk are yellow, and those which 

 form the rays are of a dusky red ; these continue 

 till the seed is ripe, which is in the autuinn. 



Culture. — These animal plants are increased 

 from seeds, vihich should be sown on a slight 

 hot-bed in the early spring, as March, and 

 when the plants arc a few inches high, they 

 should be pricked out on another bed previously 

 prepared to receive them, where they should re- 

 main till the advance of summer, when thev 

 may be taken up and planted out in the borders 

 of the pleasure-ground, where thev blow and 

 complete their seeds for the year following. 



They have a fine effect in their leaves and 

 flov\'crs in these situations. 



ZYGOPflVI.LUM, a genus comprising 

 plants of the herbaceous and woody succulent 

 exotic kind. 



It belongs to the class and order Decanchia 

 Monogynia, and ranks in the natural order of 

 Ri/fjiea. 



The characters are: that the calyx consists of 

 five oval, obtuse, concave, erect leaves : the 

 corolla has five obtuse petals emarginated at top, 

 and a ten-leaved closed nectarium, which in- 

 cludes the germcn : the stamina, ten awl-shaped 

 filaments, and oblong iucuinbent antherie : the 

 pistilluni, an oblong germen, awl-shaped stvle, 

 crowned by a simple stigina: the pericarpium, 

 an oval, pentaeonous, quinquevalvulous capsule 

 of five cells, having; many roundish seeds. 



The species are : 1 . Z. Fahago, Common Bean 

 Caper; 2. Z. sasi/ijotium, Atiican'Bean Caper; 

 3. Z Morgsana, Purslane-leaved ^Ethiopian Bean 

 Caper; 4. Z. spinostim, Thorny Bean Caper j 

 3. Z. allium. White Eg\ptian Bean Caper. 



The first has a thick, fleshy, deeply-striking, 

 perennial root: the stalks upright, round, 

 smooth, jointed, herbaceous, green, three or 

 four feet in height, being set with oval, smooth, 

 flcthy, blueish-green leaves, two or three to- 

 gether on each petiole, and reddish flowers by 

 two or three together at the axillas of the stalks, 

 ajipearing in July, succeeded by long capsules, 

 corilaining the seed, ripening in autumn. It is 

 durable in root ; but the stalks, being herbaceous, 

 perish every autumn. It is a native of Asia. 



The second species rises with an upright 

 woody stem, branching numerously and iriegn- 

 larly, three or four feet in height : the leaves 

 oval spear-shaped, thick, smooth, succulent, 

 sessile, surrounding the branches by fours : the 

 flowers yellow, on long slender footstalks at the
