May, 1913-] THE ORCHID REVIEW. 139 
side branches and seventy flowers, forming a picture. Many others were 
noticed elsewhere, and various secondary hybrids were beginning to flower, 
and showed great diversity in coloration. Three of these were specially 
striking, and as Messrs. Charlesworth kindly gave us a series of flowers it 
was possible to study them in some detail. Two forms of O. Royal Gem 
(Vuylstekeze x Odontoglossum armainvillierense) were very diverse, one 
having a white ground with a large rosy blotch above the base of the 
segments and some small spots towards the apex, while the other had a rosy 
ground with numerous darker spots. Four seedlings of O. Joan (Charles- 
worthii X Odontoglossum armainvillierense) were producing their first 
flowers, and showed a wide range of variation. One had light yellow ground 
colour, and the sepals and petals barred with rich red brown, the ‘ip being 
pandurate, with a large red-brown blotch in front of the crest, and numerous 
smaller spots at the base. A second was larger, and so much more blotched 
as to have only yellow lines all over the segments, while the similarly- 
coloured lip was deltoid in shape. A third was again larger, with a deltoid 
lip, and many basal spots, while the other segments were heavily blotched 
with red on a yellow ground. The fourth had almost brick-red flowers, 
with traces of yellow lines, and a deltoid lip with a very broad base. 
Lastly may be mentioned five seedlings of O. Patricia (Charlesworthii X 
‘Odontoglossum Phoebe), showing a remarkable range of variation. As they 
are described in the Scientific Committee’s Report at page 167 their 
characters need not be repeated. 
Passing along to Odontoglossums, another remarkable case of variation 
Was pointed out. Odontoglossum Scottianum, named in compliment to 
Sir Benjamin Scott, of Carlisle, showed several distinct forms out of the 
Same batch. The parentage is rather interesting, viz., O. oakwoodiense X 
armainvillierense. O. oakwoodiense is a plant of Mr. Cookson’s, which we do 
not distinctly remember, but it is said to be either a form of O. Wileckeanum 
or a natural hybrid between O. luteopurpureum and some other species. 
The results obtained from crossing this with a finely spotted O. armain- 
villierense were very extraordinary. There were in flower plants which to 
the casual observer looked like pure spotted armainvillierense, others more 
like large plain Pescatorei, and some looking fairly intermediate but with 
the blotching more inclined towards the brown of the luteopurpureum. 
There is also a plain white form resembling a particularly good O. crispum, 
the flower being almost round, and of splendid substance. Upon looking 
at it carefully one can see a slight influence of O. luteopurpureum in the 
lip, but to all intents and purposes it looks like a pure crispum. One very 
Pretty form had'the ground colour of the lip clear yellow, and a tinge of the 
Same colour in the sepals and petals, showing clearly a-reversion to the 
8tound colour of O. luteopurpureum.
