180 THE ORCHID REVIEW. [JUNE, 1907, 
ODONTOGLOSSUM x PRINCE EDWARD OF WALES. 
THE spike of the very handsome Odontoglossam x Prince Edward of 
Wales has been sent from the collection of William Thompson, Esq., 
Walton Grange, Stone, by Mr. Stevens. It was exhibited by Messrs.. 
Sander and Sons, St. Albans, at the R.H.S. meeting held on April 30th, 
under the name of O. X Prince Edward of Wales, and received a First- 
class Certificate, the parentage being given as O. X Rolfe. @ X crispo- 
Harryanum ¢. The plant is remarkably vigorous, and the spike originally 
bore twelve very fine flowers. In shape these are most comparable with O. 
X crispo-Harryanum, but the ground colour is white, and the very copious: 
blotching may be described as light claret-purple, with the centre of the: 
disc yellow. The lower flowers measure over 3} inches from tip to tip of 
the petals, which themselves are 1} inches broad, and the dorsal sepal an 
inch broad. The markings on the sepals take the form of three broad barsr 
and those on the petals are more like zones of confluent blotches, while the 
basal half of the lip is crowded with numerous small blotches and dots,. 
the latter chiefly near the margin. It also received a First-class Certificate 
from the Manchester Orchid Society on May 16th, when exhibited by Mr. 
Thompson. 
The appearance of this hybrid raises a rather curious question of nomen- 
clature, one phase of which is alluded to by Mr. Stevens. There is a strong 
family resemblance to several earlier hybrids, and an analysis of parentage 
shows that we have five recognised hybrids, of distinct origin, descended 
from the same three original species, O. crispum, Harryanum, and Pesca~ 
torei, as follows :— 
I. O. X percultum (Rolfee x ardentissimum). 
O. X Ossultoni (crispo-Harryanum X Pescatorei). 
O. X venustulum (crispo-Harryanum X ardentissimum). 
O. X Lambeauianum (Rolfez xX crispum). 
O. X Prince Edward of Wales (Rolfee x crispo-Harryanum). 
ll would appear distinct, but an analysis of parentage would bracket © 
and 2 together, also 3 and 4, thus :-— 
O. Pescatorei 4, crispum 4, Harryanum } = O. x percultum (Ossul- 
toni). 
O. crispum 4, Harryanum 4, Pescatorei 4, == O. X venustulum (Lam- 
_ beauianum). ; 
O. Harryanum 4, crispum }, Pescatorei +, = O. X Prince Edward of 
Wales. 
And a hybrid of identical composition to the last might be obtained by 
crossing O. Harryanum with O. X ardentissimum. 
Later on we may get further combinations i in-which these three species
