[August, 1916. 



Odonfoglossum Insleayi. 



Odontoglossum Insleayi. — The bulbs 

 and leaves of this plant resemble closely those 

 of the better known O. grande. The sepals 

 and petals are pale greenish-yellow barred 

 with reddish-brown ; the lip bright yellow 

 bordered with a belt of red spots. In the 

 variety splendens the flowers are larger, 

 especially the lip ; in the variety aureum the 

 red blotches are absent. O. Insleayi was 

 introduced by Mr. Barker, of Birmingham, 

 about the year 1838, through his collector, 

 Ross, who met with it in the neighbourhood 

 of Oaxaca in Mexico. In 1866 it was 

 imported in quantity by Messrs. Low and Co., 

 who were also the introducers of the variety 

 splendens. The specific name was given by 

 Mr. Barker, in compliment to Insleay, his 

 gardener, at the time of its introduction. A 

 warm position in the Odontoglossum house, 

 with slightly more light than usually given to 

 the genus suits its requirements. The plant 

 enjoys a certain period of rest during the 

 winter season, when only sufficient water to 

 prevent the bulbs shrivelling will be required.

ODONTOGLOSSUM ASTILBE. 



(tripudians X crispo-Harryanum.) 



For the purposes of analogy I made this 

 cross to watch the resulting parallelism to the 

 crispum Harryanum line of hybrids. The 

 result is almost identical in the progression 

 and reversion respectively. 



The sepals are basically yellow, which 

 forms a narrow margin around them ; the 

 front and backs are overlaid by rose colour, 

 and the inner two-thirds heavily covered by 

 a lilac shaded brown marbling ; in the dorsal 

 sepal it is almost solid. 



The petals have a similar arrangement of 

 colour, but are more marbled than solid as 

 regards the lilac-brown. The lip is white, 

 tinged with a lilac suffusion, the lower half 

 covered by minute spots of deep lilac. Crest 

 and column bright yellow. 



The evidence of tripudians is very strong 

 in the shade of lilac in the lip. The petals 

 are in flatter plane with the sepals, owing to 

 the influence of crispum, than in Astarte, 

 which is tripudians and Harryanum, and in 

 whose sepals and petals the heavy brown is 

 almost absolutely solid. The Harryanum 

 influence in the general form is also very 

 evident. — de B. Crawshay, July 2nd, igi6.
