D. thyrsiflo'ra is the handsomest plant of this 

 order, and one of the best stove plants in cultiva- 

 tion, for winter or late autumnal flowering. We 

 have seen it, under liberal treatment, rise to ten 

 feet, branched all round, and every branch ending 

 in a long spike or thyrse of densely-set, sky-blue 

 flowers. When the flowers begin to expand, it 

 may be removed to a warm conservatory, where ii 

 will last in bloom from six weeks to two months 

 Stove herbaceous perennials, from Brazil. Di- 

 vision of the plant, when growth is commencing ; 

 seeds sown in a hotbed in spring ; peat and loan 

 with sand and leaf-mould. Summer temp., 60 

 to 80 ; winter, 45 to 55.

DICKS O'NIA. (Named after James 

 Dickson, a British /botanist, who studied 

 this Nat. ord., Ferns [Polypodiacesej. 

 Linn., 2-Cryptoyamia 1-Filices.) 



Who that has visited the first resting-place of 

 the remains of Napoleon Buonaparte, at St. 

 Helena, did not admire the native tree-ferns, 

 D. arbore'scens, a little beyond ? To transport 

 this memorial, with the weeping willow, to our own 

 and other shores, any time within a month before 

 your departure from the island, cut off all the 

 branches or fronds to within two inches of the 

 stem, making a clean cut from the under-side ; 

 clear away the soil till you see the fang-like roots ; 

 cut them with a chisel and mallet without moving 

 the stem ; smooth the cut end of the roots, and 

 the trunk is ready to travel, packed in a dry case, 

 When the gardener receives it, let him set the 

 bottom of the trunk on a bed or box of half sand, 

 and half peat, in a temperature of 80, and give 

 no water for the first six weeks. The new leaves 

 by that time issue from the top ; water then in 

 abundance. Thus any of the colossal Ferns or 

 Cacti may be safely removed. Division of the 

 roots ; best done when growth is commencing ; 

 peat and loam. Summer temp., 60 to 80; 

 winter, 48 to 55.

Annuals, by seed in a hotbed, in spring ; peren- 

 nials, by cuttings of side-shoots, or the points of 

 shoots, in sandy soil, in bottom-heat, with a 

 hand-light, not so close as a bell-glass. Loam 

 and peat, open and fibry, with a little rotten leaf- 

 mould. Summer temp., 60 to 85 ; winter, 48 

 to 55.

DICTA'MNUS. Fraxinella, or Dittany. 

 (Diclamnus, a name adopted from Virgil; 

 Fraxinella a diminutive of fraxinus, the 

 ash, from the similarity of their leaves. 

 Nat. ord., Rueworts [Rutacese]. Linn., 

 IQ-Decandria l-Monogynia.) 



This is one of the oldest and best border-plants 

 of our cottage-gardens. Instances are known 

 here the Fraxinella has outlived father, son, and 

 and grandson in the same spot, without increase, 

 all attempts at multiplying it, to give away a 

 rooted slip to a newly-married member of the 

 "amily, having failed ; yet the Fraxinella is easily 

 ncreased from seeds. Sow, as soon as they are 

 ipe, in the common soil of the border, and cover 

 jne inch deep ; they will not sprout till the follow- 

 ng April. If they are kept over the winter, and 

 sown in the following spring, they will remain 

 ;welve months before they sprout ; and not one 

 iced put of a hundred sprouts at all. When the 

 seedlings are two years old, transplant them 

 vhere they are to remain, &nd they will flower the 

 bird season. They prefer a deep, rich border, OQ 

 a dry bottom, and all flower in June.
