HACQUETIA (named after Balthasar Hacquct, 

 1740-1815, author of " Plante Alpinse Carniolicae "). 

 STNS. Dondia, Dondisia. OBD. Umbelliferoe. A mono- 

 typic genus. The species is a pretty little alpine her- 

 baceous perennial, thriving in good stiff loam. It is 

 a slow-growing subject, and should not be disturbed. 

 Propagation must, therefore, only be undertaken in the 

 case of strong healthy clumps, which are best divided 

 before growth commences, in spring. 

 H. Epipactis (Epipactis).* ft. yellow, on short pedicels ; scapes 



one to three, bearing at their tops simple umbels ; involucre 



of five or six obovate leaves, which are longer than the umbels. 



Spring. 1. radical, petiolate, palmate ; leaflets three, cuneated, 



two or three-cleft, h. Sin. to 6m. Europe, 1823. (L. B. C. 1832.)

H2EMANTHUS (from haima, blood, and anthos, a 

 flower; referring to the colour of the spathe and fila- 

 ments of some species). Blood Flower. OKD. Amaryllidece. 

 A genus of about thirty species of fine stove or green- 

 house bulbous plants, all with the exception of about 

 five species from tropical Africa natives of South Africa. 

 Scape, involucre, umbels, and stamens, all add their quota 

 to the interest and beauty of these curious flowers, which, 

 in some of the species, are gathered together into closely 

 compact umbels, and present in the mass a sort of 

 filamentous appearance, somewhat resembling that of the 

 feathered Hyacinth. The culture of H. sanguineus, and 

 its allies of similar habit, is of the simplest nature. The 

 various species blossom at different seasons, and it is 

 important that, after flowering, each should have a period 

 of growth, to be followed by one of rest. A mixture of 

 sandy loam and fibrous peat is most suitable, and the 

 plants flower more freely when under-potted. For this 

 reason, it is not necessary to shift them every year. 

 As the bulbs grow, and the strong roots increase, both 

 may be stimulated and supported with weak manure 

 water. Although some of the species of Hcemanthus are 

 frequently described as cool greenhouse bulbs, and some 

 even recommend cultivating them in warm borders in the 

 open air, yet they succeed best in a temperature of from 

 SOdog. to 60deg. during the growing season. The sorts 

 with well-developed bulbs should have these quite buried 

 in the soil. When in flower, the blossoms will last longer 

 in cooler quarters. Propagation is effected by offsets, 

 which are produced more or less profusely. They should 

 be removed and potted when the plants are commencing 

 new growth, and be kept in a close pit or house till 

 established. The offsets will reach flowering size all the 

 sooner if kept in a temperature as recommended above 

 for the growing season.

 spherical head, appearing before the leaves; peduncles lin. to

H. deformis (deformed). fl. pure white, numerous, shorter 

 than the involucre ; head compressed, parallel to the bulb ; 

 involucral spathes about six, equal, erect, obovate-oblong, obtuse, 

 ciliate, pure white ; perianth tube shorter than the erect, linear, 

 obtuse lobes ; stamens exserted ; anthers pale yellow ; scape very 

 short, sessile amongst the leaves. March. I. about two pairs, 

 3iin. to 4in. long and broad, dark green, smooth, hairy above, 

 pubescent beneath. Bulb 4in. to 5in. in diameter, slightly com- 

 pressed, h. 3in. Natal, 1869. A singular and grotesque species.

H, incarnatus (flesn-coloured). This species is closely allied 

 to H. tigrinui, but is a more elegant plant, with broader leaves ; 

 the scape more slender ; the divisions of the spathe smaller, nar- 

 rower, and less coloured; the flowers smaller, and of a different 

 colour. South Africa, 1865. (B. M. 5532.)

 one-hundred-flowered, dense, globose, about 6in. in diameter.

 spotted stem. Sierra Leone, 1783. (B. M. 961 and 1995.) 



H. natalensis (Natal).* This species is closely allied to H. 

 insignis, but may be distinguished from it by the large, beautifully 

 coloured and dotted, sheathing scales at the base of the plant, 

 by the much longer leaves, by the pale green flowers, the orange- 

 coloured stamens and styles, and by the nearly uniform bracts of 

 the involucre, of a rich ferruginous purple, shorter than the 

 flowers. February. Natal, 1862. A handsome greenhouse plant.
