1. Halleria Lucida; African Fly-Honeysuckle. This plant 

 grows to the height of six or eight feet, with a woody stem, 

 well furnished with branches ; leaves ovate, serrate, opposite, 

 and continuing' green through the year; the flowers come 

 out singly, and are of a red colour, but being intermixed 

 with the leaves, and growing scatteringly on the branches, 

 are not easily discerned ; they come out in June, and the 

 seeds ripen in September. Native of the Cape of Good 

 Hope. These may be propagated by cuttings; which, if 

 planted in June, in pots of light earth, will soon take root: 

 the plants may be exposed in summer, and will require plenty 

 of water at that season ; in the winter they must be housed 

 with the Myrtles, and other hardy exotics, which require 

 much air in mild weather. 



2. Halleria Elliptica. Leaves elliptical, acute, strongly 

 serrated ; calix four-cleft. The leaves of this are thicker 

 than those of the former, tapering at each end, and more 

 coarsely serrated ; and the corolla less curved. Common in 

 woods at the Cape. 



Halm, or Helme. See Arundo Arenana.

 petals four, oblong, blunt, concave, spreading, with narrow 

 claws, inserted into the calix. Stamina: filamenta eight, 

 filiform, upright, shorter than the corolla, inserted into the 

 calix; antheree oblong, four-furrowed, upright Pistil: ger- 

 men inferior; styles four, upright; stigmas simple, blunt.

 cell. ESSENTIAL CHARACTER. Calix : four-cleft, superior. 



Petals : four. Drupe : dry, enclosing a four-celled nut. 



The species are, 



1. Haloragis Prostrata. Leaves oblong, quite entire, mu- 

 cronate ; branches four-cornered, smooth ; flowers axillary, 

 solitary, pedicelled ; fruits globular. When the fruit is in a 

 state of maturity, the plant greatly resembles the Ammannia 

 Latifotia. Native of Botany island, near New Caledonia; 

 and found in the Isle of Pines, in the South Seas. 



2. Haloragis Cercodia. Leaves serrate; flowers about six 

 in a whorl. The plant is about two feet high, branched, 

 panicled, and upright; stalk quadrangular, and red, small, 

 green, with a red tinge, pendulous. Native of New Zealand. 



3. Haloragis Racemosa. Leaves lanceolate, serrated ; 

 flowers in terminal and axillary clusters ; stem shrubby, 

 branched, near two feet high. Native of the south coast of 

 New Holland. 



4. Haloragis Diygnia. Leaves scattered, linear, entire ; 

 clusters leafy, terminal. Native of the same part as the 

 preceding. 



Hamamelis ; a genus of the class Tetrandria, order Digy- 

 nia. -GENERIC CHARACTER. Calix: involucre three-leaved, 

 three-flowered; the two inner leaflets roundish, smaller, 

 blunt; the outmost larger, lanceolate; perianth double; 

 the outer two-leaved, smaller, roundish ; the inner four- 

 leaved, upright; the leaflets oblong, blunt, equal. Corolla: 

 petals four, linear, equal, very long, blunt, reflex ; nectary of 

 four truncate leaflets, growing to the corolla. Stamina: h'la- 

 menta four, linear, snorter than the calix ; antherse two- 

 horned, bent in. Pistil: germen ovate, villose, ending in 

 two styles, which are of the same length with the stamina; 

 stigmas capitate. Pericarp : nut ovate, half covered with 

 the calix, blunt, furrowed on both sides at the tip, having 

 two little horns spreading horizontally, two-celled, two- 

 valved. Seeds : one in each cell, oblong, narrow at the base. 

 ESSENTIAL CHARACTER. Involucre: three-leaved. Peri- 



anth: four-leaved. Petals: four. Nut: two-horned, two- 

 celled. The species are, 



1. Hamamelis Virginica; Witch Hazel. This tree has a 

 woody stem, from two to three feet high, sending out many 

 slender branches ; leaves oval, indented on their edges, hav- 

 ing great resemblance to those of the Hazel, and placed 

 alternately on the branches : these leaves fall away in autumn, 

 and then the flowers come out in clusters from the joints, 

 but are not followed by seeds in England. The Indians con- 

 sider this tree as a valuable article in their materia medica; 

 they apply the bark, which is sedative and discutient, to 

 painful tumors and external inflammations. A cataplasm of 

 the inner rind is said to be very efficacious in removing 

 painful inflammations of the eyes. Native of America, 

 from Canada to Carolina. This plant is propagated by 

 laying down the young branches in autumn ; they will take 

 root in a year, if sufficiently watered in dry weather. Many 

 of the plants in our gardens have been produced from seeds 

 imported from America : these always remain a year in the 

 ground, so that they should be sown in pots for the conve- 

 nience of plunging them into the earth in a shady part of 

 the garden, where they may remain all the summer, and will 

 only require to be kept free from weeds, and to be watered 

 in very dry weather. 



2. Hamamelis Macrophylla. Leaves large, punctated on 

 their lower side with rough tubercles. Found in Georgia, 

 and North Carolina. 



3. Hamamelis Parvifolia. Leaves smaller, oblong-ovate, 

 upper part undulated and grossly crenate, under side pubes- 

 cent, somewhat hirsute ; segments of the calix oblong ; sta- 

 mens and perigynous filaments often nearly equal. A shrub 

 every way smaller than the first species ; the calix somewhat 

 coloured and diaphanous, and petals bright yellow. Found 

 on the mountains of Pennsylvania. 



Hamellia; a genus of the class Pentandria, order Mono- 

 gynia. GENERIC CHARACTER. Calix: perianth five- 

 parted, acute, very small, superior, upright, permanent. 

 Corolla : monopetalous ; tube five-cornered, very long ; bor- 

 der five-parted, equal, small, acute. Stamina : filamenta 

 subulate, inserted at the middle of the corolla; antherse 

 oblong, linear, the same length with the corolla. Pistil : 

 germen ovate, with a conical tip, inferior; style filiform, the 

 same length with the corolla; stigma linear, blunt. Pericarp: 

 berry oval, furrowed, five-celled, crowned. Seeds: very 

 many, roundish, compressed, very small. ESSENTIAL 

 CHARACTER. Corolla: five-cleft. Berry: five-celled, in- 

 ferior, many-seeded. The species are, 



1. Hamellia Patens. Racemes terminating, coloured; 

 leaves ternate, villose, pubescent. This is a shrub, or small 

 tree, growing five or six feet high ; branches diverging, 

 spreading, round, smooth ; petioles coloured ; the midrib red ; 

 flowers directed one way, subsessile, distant, bright red or 

 scarlet. Native of the hedges and mountains of Hispaniola. 

 This plant is propagated by seeds when they can be procured 

 ffesh from the country where it naturally grows. They 

 should be sown in small pots, and plunged into a moderate 

 hot-bed. The plants generally appear in five or six weeks, 

 and should then be treated in the same way as other plants 

 from the same countries ; admitting air in warm weather, 

 and gently refreshing them with water. As the seeds are 

 seldom brought to England, the plant may be propagated by 

 cuttings, which, if planted in small pots, plunged into a 

 moderate hot-bed, and closely covered with either bell or 

 hand glasses, will put out roots in about six weeks. They 

 flower in July, and make a pretty appearance. 



2. Hamellia Grandiflora. Clusters terminal or axillary;
