to potted plants. Heaths, New Holland species, and, indeed, every sort of exotic 
shrub, grows and blooms better when its collar is above the soil, so that the trunk 
of the principal roots is just visible. We always consider it a mark of a skilful 
cultivator, when the outline of the ball of earth which the plant had while in a 
previous pot, is perceptible after it has been shifted into a larger one, and is not 
buried as is most usually done. It is exceedingly doubtful whether the practice of 
renewing the surface soil of plants that are not shifted at the periodical potting be 
not open to all the objections we have urged against deep planting. ^ ^

NEW OR BEAUTIFUL PLANTS FIGURED IN THE LEADING BOTANICAL PERIODICALS 
FOR OCTOBER. 
Ae'rides CRi'sPUM. The same species lately figured in oui' Magazine under the name of 
A. Brookii, and to which, it appears, Mr. Bateman had inadvertently applied that title, under the 
belief that it had not been previously described. Dr. Lindley, however, identifies it with the 
A. crispum of his work on Orchidacese, and it must, therefore, in future, bear that appellation.

Dendro'bium macra'nthum. In figuring this splendid plant, Sir W. J. Hooker suggests that 
the name of D. macrophyllum, which it has heretofore been known by, must be a misprint for 
D. macranihum. This was at first our impression, and we noticed it originally by the latter 
name ; but altered it to D. macrophyllum on the authority of Dr. Lindley, as occurring in the 
Botanical Register. We now await further explanations. Bot. Mag. 3970. 
Echinoca'ctus centete^rius. " This has been for some time cultivated in the Royal Botanic 
Gardens of Kew, under the name here adopted. If it be the same with the E. centeterius 
Lehmann and Pfeiffer, the plant from which the latter author's description was made was bui, 
young, for it is mentioned as two inches and three-quarters high, and three inches broad, with 
flowers an inch and a half in diameter. In other respects, the two plants appear to be the same. 
The best of descriptions, however, give but an imperfect idea of the distinguishing marks in this 
extensive and curious family. In the specimen before us, the height is above six inches, and 
the breadth somewhat less. The flowers arc copious, five to seven or eight on the summit of the 
plant ; each is nearly three inches across ; the petals are deep straw colour, with a reddish 
streak down the centre. The filaments are reddish, and the anthers yellow." It is handsome, 
and flowers abundantly in July. Bot. Mag. 3974. 
Gloxi'nia tubiflo'ra. a remarkable new species, which "seems to have nearly as strong a » 
claim to be considered a Gesnera as a Gloxinia^ or, rather, it appearsalmost to unite the two genera. 
It is one of the many interesting novelties reared by Mr. Moore, of the Glasnevin Botanic 
Garden, from seeds sent by Mr. Tweedie from Buenos Ayres. It is probable he obtained the 
seeds from South Brazil, or, it has been suspected, from Paraguay." The plant has short stems, 
opposite oblong leaves, and graceful terminal panicles of flowers. These last are white and 
downy, with a " tube four inches long, a little enlarged and curved upwards, with a very con- 
spicuous broad spur or gibbosity ; the limb an inch and a half broad, spreading, equally five-lobed." 
The length of the tube of the blossoms, and their delicate whiteness, will render the species 
exceedingly desirable. Bot. Mag. 3971. 
Helle'borus oly'mptcus. " A native of the Bithynian Olympus, whence it was sent to the 
Horticultural Society by Mr. Sandison, her Majesty's consul at Brusa." Its leaves are palmate 
and thick, and the leaflets are finely toothed. The flowers are large, greenish-white, and 
appearing late in the autumn. " It is a hardy herbaceous plant, requiring a rather moist situation,
