AXD THEIR MANAGEMENT. 



Dendrobium. 



liin. broad, deciduous. Flowers in pairs from the joints of tlie 

 ripened new growths, each 4in. across ; sepals lance-shaped, 

 petals as broad again, both rich magenta-purple ; lip folded 

 at the base, heart-shaped in front, hairy on the upper surface, 

 and coloured crimson-purple, paler at the apex. Odour powerful, 

 like that of rhubarb. Philippines, 1S40. Syns. D. jiiacrantludii, 

 D. macrophylluiu. (B. M., t. 3970.) 



A'ar. anosmiiin. — Stems shorter. Flowers usually produced 

 singly, and almost odourless. 



Yar. Biirkei. — Flowers white, with two light blush rose cheeks 

 on the base of the disk of the yellowish-white lip. 18S4. A 

 very scarce and desirable variety. 



Var. Hiittoiii. — Stems slender. Flowers white, purple in the 

 throat. 



D. thyrsiflorum {Rchb. /.). — This plant is almost identical 

 with that already described under the name of D. di-iisi_florum 

 var. Schriederi, the only difterence between the two being in 

 the characters of the pseudo-bulbs, those of the former being 

 without angles, from i-Jjft. to 2ft. high, and brownish when 

 mature ; whilst in the latter they are four-angled, short, and 

 green. The flowers of the two are identical. Both plants are 

 ranked among the most beautiful of all Orchids ; they are easily 

 grown, and blossom freely and regularly every spring (about 

 April). Burma, 1S64. (B, M., t. 57S0.) 



D. tortile (Liiidl.). — A pretty species, not unlike D. pri)itu- 

 linuin. The pseudo-bulbs are club-shaped, ift. long, slightly 

 compressed and zigzag, yellowish when old. Leaves lance- 

 shaped, 3in. long. Flowers 3in. across ; sepals and petals 

 narrow, twisted, rosy-lilac; lip broad, woolly or "frosted" on 

 the upper surface, and coloured pale primrose-yellow, with a 

 purplish blotch in the throat. Tenasserim, 1847. (B. M., t. 4477.) 



D. transparens (IVall.). — A beautiful species, with erect, 

 smooth, slender pseudo-bulbs, about ift. long, and narrow 

 deciduous leaves 3in. long. Flowers in pairs on the ripened 

 leafless pseudo-bulbs, each i?,in. across; sepals lance-shaped; 

 petals broader, both coloured pale lilac, tipped with rose; lip 

 shaped as in D. nobile, white, with two purple blotches in front, 

 and pale purple at the apex. Assam, 1S52. (B. M., t, 4663.) 



D. Wardianum ( ]Var?i.). — One of the most useful and beauti- 

 ful Dendrobiums. The pseudo-bulbs are from 2ft. to 4ft. long, 

 as thick as a man's finger, knotted and pendent. The leaves are 

 lance-shaped, 4in. long, deciduous (falling off before the blossoms 

 appear). The flowers are produced during the months 'of March 

 and April ; they grow in threes on opposite sides of the greater
