Phajus Incarvillei 0. K. 



Coll. J. J. S. in horto bog., Nov. 1910. 



Habitat Arch. Mai. 



Two dimerous flowers (the ovaries are also two-celled). 



Sepals grown together to a tube which encloses the rest of 

 the flower, (fig. 13). 



In both we found a well-developed lip aud a petal of nor- 

 mal shape. 



Column straight, compressed from front to back. In one of 

 the flowers no anther, in the other a normal one. In the former 

 the labellum closed round the petal, in the latter it was folded 

 and pressed against the petal. 



The flowers in question, owing to the tubular shape of the 

 calyx, can not expand unless the latter be torn up through 

 the pressure of the growing lip '). 



Phalaenopsis amabilis Bl. 



Coll. Dr. W. Docters van Leeuwen in horto Jacobson. Samarang, 

 Febr. 1910. 



Habitat Arch. Mai. 



Very fine pelories, 3 specimens (fig. 1-4). Flower almost 

 regular. Petals much narrower than usual. Labellum aud petals 

 are perfectly alike without any incision or appendage. 



Pes columnae altogether wanting. The column shows six 

 little lobes at top which correspond with stamens, one of them 

 bearing a (somewhat transformed) anther, the others only 

 anther-like indications. At the base of the developed anther 

 we found a bifid rostellum. 



Masters, in his Vegetable Teratology, 2 ) mentions a pelory of 

 Phalaenopsis amabilis without, however, entering into details 

 and refers to a similar case in Ph. Schilleriana, which though 

 regular in its calyx and corolla, possessed unaffected column 

 and anther-cells. 



1) Attention is drawn to the fact that the flowers of Phajus on contusion and 

 also by immersion into alcohol show indigo-colouring. The same thing occurs in 

 Calanthe.
