and consequently do not diverge but bend inward. The concave 

 portion is moreover at the innerside irregularly striped yellow 

 and shoves a few little red specklets (normally snow-v^ite). 

 On the left petal there is a swollen excrescence calling to 

 mind the „Scliwiele" of the lip. Evidently we have here to do 

 with a beginning transformation of the petals into labella. The 

 lateral sepals show a yellowish hue. All the flowers of the 

 raceme had been thus affected.

The normal plant has flat pseudo- tubers bearing one narrow 

 leaf at the top. The peduncle springs from the axil of one of 

 the sheaths at the base of the tubers. The erratic specimen of 

 which Dr. S. writes has already been cultivated in the Gardens 

 a long time without showing any deviation. Towards the end 

 of 1908, however, the plant bore a couple of pseudo-tubers 

 each with a leaf the margins of which firmly cohered. In con- 

 sequence of this the leaves were much like sheaths somewhat 

 flattened and with a small hole at the top. 



At the same time the plant produced an abnormal peduncle 

 on which were to be distinguished the following ijortions : 



1". with normal bracts and flowers, length 92.5 cM. 



2". with 7 ordinary leaves, ') length 24- cM. 



S*^. with normal bracts and flowers, length 48 cM. 



After the flowers of the lowest portion had fallen there were 

 created buds in the axils of the bracts, two of which grew to 

 normal, stout, root bearing shoots. 



1) These leaves, to 82 mm. long, were much shorter than those at the top of 

 the tubers.
