DEWBEKRY 



(var. rorihaceus, Bailey), which is a stronger plant, 

 with weilge-ovate, jagged leaflets, long flower stalks, 

 large flow'ers and leaf-like sepals. Figs. 697, 698. (2)

The culture of tne Dewberry is much the s ime i 

 that of the blackberrj except m the matter of tr lining 

 though It IS thought to thrne better on lulit an 1 

 sandj soils than the blackbeirv No summer \ imiin, 

 of the canes is needed although the old cane m i\ 1 e 

 removed as soon as done fiuiting \ irious nieth 

 ods of training are emplcNed the object of all be 

 ing to keep the bearing cane ofi the ^round so that 

 they will not interfeie with cultivation and the fruit will 

 be kept clean. For this purpose the single stake and 

 the wire trellis methods are best known. Tying the 

 canes to stakes (Fig. 699) is perhaps the be.st method. 

 The fruiting canes are tied to the stake or trellis in 

 spring, being shortened to from 3 to 5 feet in length. 

 The young canes are allowed to grow upon the ground 

 at will, or at most are turned in the direction of the row 

 If they interfere with cultivation. They remain in this 

 position during winter, where they can be very con- 

 veniently protected, and take their place upon the trellis 

 or stakes the following summer. 



The Dewberries have proved successful and profitable 

 with some and a failure with others. Different varieties 

 should be planted together to insure proper fecundation 

 of the blossom.s. Their chief value lies in their season 

 of ripening, which is in advance of the blackberries. 

 Lucretia and Bartel are the most important varieties.

DIACKIUM (through and point; the stems are sur- 

 rounded by sheaths). Urchidicece, tribe Epidindrea. 

 Four tropical Amer. epiphytes, closely allied to Epi- 

 dendrum, with which they have been included. Differs 

 from that genus in the fact that the column and lip are 

 not united. Fls. showy, in loose racemes : Ivs. few, 

 sheathing : pseudobulbs slender. Culture of Epiden- 

 drum and Cattleya. 



bicomitum, Benth. (Epidendrum fticojiiiifion.Hook.). 

 Pseudobulbs 1-2 ft. long, hollow, bearing dry sheaths: 

 Ivs. short and leathery: raceme slender, 3-12-fld. : the 

 Hs. white, with small crimson spots on the 3-lobed lip, 

 fragrant. B.M. 3332. G.C. III. 16:337. J. H. III. 33:29. 

 — A handsome orchid, requiring high temperature. 



D. bidentatum. Hemsl. (Epidendrum bidentdtum, Lindl.), 

 of Mexico, has been listed in trade catalogues, but it is practi- 

 cally unknown to cult., and is probably not now in the Amer.

DIAMOND FLOWER. 



DIANELLA (diniinuth 



/..»« 



Tender 



perennial fibrous rooted id^aits. with hard, linear, sheath- 

 ing, grass-like Ivs., often 2-3 ft. long, large, loose 

 panicles of blue fls. on delicate, pendent pedicels, and 

 great numbers of pretty blue berries, which remain at- 

 tractive for several weeks, and are the chief charm of 

 the plant. There are about a dozen species of world- 

 wide distribution. They perhaps succeed best in the 

 open border of a cool greenhouse. Prop, by divisions, 

 or by seeds sown in spring in mild heat. A few plants 

 have lately been imported, but the species are not ad- 

 vertised. Latest monograph by J. G. Baker, in Journ. 

 Linn. Soo. 14:574 (1875).

 carelessly grasped : panicle very lax, sur-
