Epidendrum vitellinum, Lindl. 455 
consisting of but a few spiral vessels, and branch in an 
irregular manner. A longitudinal section of a young bud 
(Fig. 5) shows clearly the four whorls in which the members 
are arranged. 
Conclusion . The flower has attempted to assume a regular 
form by the arrest of the irregular parts (regular peloria). 
This has been accomplished in the case of the sepals and 
petals. The stamens have become free from one another, and 
more or less petaloid. The styles are probably still connate 
with the inner whorl of stamens. No trace of pollen or ovules 
was to be found. 
The flowers, from which this description has been drawn 
up, were received in July, 1891, from Mr. W. Swan, gardener 
to G. C. Raphael, Esq., of Castle Hill, Englefield Green.
