to injure the tubers during the process of potting. 

 The crowns should not be entirely covered with 

 the compost, but it should be brought up to where 

 roots are produced. little direct watering is 

 necessary for the first few weeks, but, as root 

 action increases, more moisture may be applied ; 

 at no time should the base of the plant be allowed 

 to become dry, for Disas are never completely at 



rest. 

 During the summer months slight sprayings 



overhead are beneficial whenever the weather is 



favourable, and air may be admitted by both the 



top and bottom ventilators; even in winter the

 highburiensis of a clear rose colour with purple 

 front to the lip. These narrow-petalled hybrids 

 exhibit bright colours and they are very flori- 

 ferous.

RHODODENDRON VASEYI. 



From a garden standpoint this species is in- 

 cluded amongst the Azaleas, for it is deciduous 

 and closely related to the various Ndrth 

 American species, from which, with one or two 

 other species, the race of shrubs known collep- 

 tively as Ghent Azaleas has originated. It 

 occupies positions on the mountain sides of Nor 

 and South Carolina, and has been known for -yd 

 considerable period, though it has never tfeen 

 grown largely in this country. Attention was 

 directed to its merits in the Garden and Forest 

 for 1888, p. 376, where an illustration also 

 appeared, and from time to time since it has 

 been noted in the pages of English horticultural 

 journals. But it is not yet so well knoNvn as

eary to shade the plants from the direct rays of

ORCHIDS FROM EVERSHOT, DORSET. 



Mr. Eustace F. Clark sends a very fine 



°wer of Odontoglossum Rossii ma jus taken from 



* Plant purchased in 1893 ; a flower of Cattleya 



^askelhana x Lselia Iona; a very distinct and 



j>ngntly-coloured form of Ladio-Cattleya high-

deep rose-veined petals. The front of the lip 



regard to parentage, to 



be checked by the 

 probabilities" as shown in the flowers. Where 

 any doubt exists, it is far better to de- 

 clare the parentage as unknown or doubt- 

 ful, as in the case of complex crosses even 

 an 'expert, in defining parentage, may easily be 

 wrong in his conclusions. The flowers from Wal- 

 ton Grange include three which are probably 

 seedlings of blotched 0. crispum, several of the 

 ardentissimum type, a clear canary-yellow 

 flower like an unblotched 0. waltoniense, a very 

 pretty 0. Adriame cross, 0. Hallio-crispum, and 

 some pretty flowers, probably sec ondary crosse s, 

 of Rolfea3. One very remarkable hybrid has 

 the flower almost entirely of a bright claret colour, 

 with spiny yellow crest, the front of the lip being 

 white. 



its usefulness warrants, therefore it may not 

 be out of place to direct attention to it again. 

 Flowering in advance of the other North Ameri- 

 can Rhododendrons, it may be found in blossom 

 towards the end of April or during the early 

 part of May. The somewhat rounded flowers 

 are from f to 1 inch across, and vary consider- 

 ably in colour on various plants, for, while the 

 blooms on one plant may be white, or white 

 slightly flushed with rose, those on other ex- 

 amples are deep rose. In the hands of the 

 hybridist it ought to prove productive of useful 

 hybrids which would flower early and so prolong 

 the season, though for some parts of the country 

 it is doubtful whether Azaleas which bloom be- 

 fore the beginning of May are to be encouraged 

 on the score of April frosts. W. IF.
