occurred in C. Harrisoniana alba x C. 
Gaskelliana alba, the flowers being also of a 
delicate pink colour. 
Considerable attention was at one time 
devoted to Dendrobiums, but only the best 
yellow flowered varieties are now taken note 
of. DendWobium Chessingtonense (aureum x 
Wiganias) is one of the most important 
additions to the yellow section, and the same 
remark applies to D. atro-Brymerianum, an 
1 n t e r e s ting 
hybridbetween

Dend ro b ium 
nobile virgin- 
ale has been 
raised true 
from seed, the 
flowers of all 
the seedlings 
being pure- 
white. 
The seed- 
ling house 
contains a 
others ; some seedlings of Odontoglossum 
Clytie X O. eximium having been pricked out 
after the seed has only been sown four weeks. 
Odontoglossum Pescatorei x Oncidium cris- 
pum IS an exceedingly slow grower, and '\vill 
probably take many years of careful culture 
before a flower spike will be produced. One 
odd seedling has assumed a tuftedl (habit of 
growth, no less than ten growths are being 
produced from the small central seedling 
growth. 
There are

Many excellent 
results have 
been produced, 
the most beau-

B. -C. Mrs. J.

C. aurea), the

seedlings 
number of pans in which the 
germinate with astonishing rapidity, and also 
some propagating cases in which the small 
pots containing the pricked-out seedlings are 
placed for a short time. After a few days 
these pots are taken out and placed on the 
usual staging. It is interesting to note that 
Odontiodas and Odontoglossums can only be 
raised by sowing the seed on the surface of 
the compost in the pots in which seedling 
Odontoglossums, etc., are growing. Some of 
the crosses germinate much quicker than 
between B. Digbyana and L. grandiflora, the 
latter parent being also known as L. majalis. 
It remains to be said that Mr. Thwaites 
has been an enthusiastic Orchid fancier for 
some twenty years, and that he was elected 
a member of the Orchid Committee of the 
Royal Horticultural Society in 1904, since 
when he has been a regular attendant. 
Close application and enthusiasm are 
essentials of the successful Orchid grower, 
and both these Mr. J. M. Black has got in 
a high degree. This collection has risen
