The garden varieties of Delphinium, as given 

 in the catalogues of nurserymen, are some of 

 them exceedingly beautiful. A few may he 

 named — dclicatwm, cardiopliaium, Sender- 

 sbni, magnificum, grandiflbrvMi, maximum, 

 formdsum, Montm&rency, Mooreanwm. 



Delta-leaved, shaped like the Greek A. 



Deltoides, triangular. 



DemAtitjm, Persoon. From a diminutive of 

 dema, a "bundle ; in reference to the mode of 

 growth. Linn. 24, Or. 9, Nat. Or. JBotrytctccce. 

 An extremely minute species of Fungi, of a 

 bluish colour, found on the stems of herbs in 

 autumn — arliculatum. 



Demulcent, having the property of softening 

 anything. 



Dendb6bium, Swartz. From dendron, a tree, 

 and bios, life ; in the places of their natural 

 growth, the species are generally found upon 

 trees. Linn. 20, Or. 1, Nat. Or. Orclvidacem. 

 No orchidaceous plants contribute more to the 

 gaiety of the stove than the species of this 

 splendid genus. D. nbbile, chrysdnthum, Qib- 

 sbni, fimbriatum, densiflbrum, and many 

 others, are equalled by few, and certainly not 

 surpassed, in the beauty of their flowers, by 

 any other orchidaceous plants ; and if the fol- 

 lowing directions be attended to, they will be 

 found very easy of culture : — All orchidaceous 

 plants require (to cultivate them successfully), 

 a season of growth, a season of rest, and a sea- 

 son for flowering ; all of which should coincide, 

 as much as possible, with the corresponding 

 seasons of those parts of the globe which they 

 so profusely inhabit ; and the species of this 

 genus should especially; be subjected to a 

 change of treatment assimilating as much as 



possible to that before mentioned, without 

 which, they will never flower in perfection. 

 In India, three seasons only are known ; the 

 hot, or dry season, which is succeeded by the 

 rainy season, and the cold, or winter season. 

 In the hot season, all, or the greater part, of 

 the plants belonging to this genus produce 

 their flowers ; in the rainy season, they make 

 their shoots ; and during the cold season, they 

 have a period of repose. The different seasons 

 being so well known, it is very easy to imitate 

 them in our hothouses, and by attending to 

 these simple rules, we should be enabled to 

 flower the species of this more abundantly 

 than those of any other orchidaceous genus, 

 besides which, they might be easily induced 

 to flower in this country at any season of the 

 year. B. chrysdnlhum, Pierardi, and some 

 others grow well when fastened singly on 

 pieces of wood, and treated as is recommended 

 under Burlinglbnia ; but they all succeed well 

 when potted in very turfy peat, raised above 

 the pot, in the same way as is recommended 

 in potting Stanhbpeas. A strong moist heat 

 is indispensable in the growing season, when 

 they may be frequently slightly syringed over- 

 head. They will be found to succeed best in 

 a warmer part of the house than the Stanhbpeas 

 require. They are propagated by detaching 

 one or more of the stems while, in a dormant 

 state, taking care not to injure the roots, and 

 potting it carefully in turfy peat soil, and not 

 much raised above the pot, which must be 

 carefully drained; the pot should then be 

 plunged in a gentle bottom heat, where the 

 plant will speedily produce new shoots. Sy-
