102 THE ORCHID REVIEW. [APRIL, Ig9I0.. 
THE AMATEUR’S COLLECTION. 
THE Cool house is now brightening up considerably, and a number of 
Odontoglossums are in flower, particularly O. Pescatorei, various forms of 
O. crispum, and the bright yellow and brown O. triumphans, which looks 
unusually brilliant among a number of its paler relations. O. Pescatorei is 
a particularly charming thing when well grown, for under such conditions 
the flowers are borne in ample panicles, and the effect is very telling. Some 
of the forms are of the purest white, brightened up with a few clear purple 
markings on the base of the lip, while others are prettily tinged with rose. 
Spotted forms are not numerous, but a few very attractive ones are to be 
met with. It grows in company with O. triumphans, and the natural hybrid 
O. X excellens, as well as O. triumphans itself, sometimes flowers among 
batches of imported plants. Of course there is not the same element 
of uncertainty as to what will appear as in growing batches of 
imported O. crispum, which presents a range of variation that is 
quite bewildering, apart from the recognised natural hybrids, some of 
which are almost certain to put in an appearance. These include O. X 
Andersonianum, x Adriane, x Wilckeanum, and x Coradinei, and all are 
worth growing for their variety and interest, as well as a plant or two of the 
parents, O. gloriosum, Hunnewellianum, luteopurpureum, and Lindley- 
anum. Various other species are flowering well, as O. Edwardii, sceptrum, 
and the charming little O. Rossii, which succeeds best when grown in deep 
pans suspended from the roof. 
The hybrids of garden origin are now becoming a very numerous class, 
and some of them are quite within the reach of the amateur grower. The 
hybrids of O. Harryanum form almost a class of themselves, and the forms 
of O. X spectabile and O. x Rolfez are easily grown and very beautiful. 
O. x Lambeauianum is a secondary hybrid of the same, which presents a 
bewildering amount of variability. O. x armainvillierense, the hybrid 
between O. Pescatorei and O. crispum, is as easily grown as its parents, and 
_ presents a varied series of exquisitely blotched, as well as a few white, forms, 
while O. x amabile is also very variable and beautiful. 
Masdevallias are flowering in increasing numbers, and the scarlet-flowered 
section will soon present an imposing display where their requirements are 
well looked after. M.caudata and severa! of the smaller flowered species 
are very attractive, and deserve more attention than they sometimes receive. 
Ada aurantiaca is an easily grown and floriferous plant, and its orange- 
coloured flowers, sometimes spotted with brown, are very effective. 
In the Intermediate house Cattleya Schroeder is now one of the most 
attractive species, but several others are rapidly approaching the flowering 
stage, and great care should be taken to prevent the developing buds from
