Coll. Dr. J. J. Smith in suo horto 1908 and 1909. 



Hab. The East Indies. 



The normally simple inflorescence splits up in two equal 

 branches of resp. 1.5 and 0.9 cM. which bifurcate in their turn. 

 The four tops are densely covered with undeveloped flowerbuds. 



The whole terminal portion does not surpass 2.5 cM. The 

 inflorescence has a length of 80 cM, of which the rachis is 

 60 cM. long. 



Although bifurcation of the inflorescence has been observed 

 in Orchis maculata, Anacamptis pyramidalis, Gymnadenia conop- 

 sea and I^igritella angustifolia '), a double dichotomy has till 

 now, for aught we know, not been registered with respect to 

 the family of the Orchidaceae. 



On this occasion we also call to mind the fasciated and 

 branched inflorescences of Bulbophyllum obscurum mentioned 

 in our former paper") and the case of bifurcation in Renan- 

 thera Lowei^). 



The specimen of Calanthe triplicata with terminal inflores- 

 cences, which Dr. Smith had also the kindness to send me, is 

 only represented by a fine drawing (fig. 6) but not described, 

 because Mr. Smith himself has devoted a paper to this and to 

 an analogous case in Grammatophyllum speciosum in the fes- 

 tive number^) in honour of Prof. Dr. M. Treub whose unex- 

 pected death in October 1910 excited general sympathy in the 

 scientific world. 



Also the flower has given occasion for observation. In looking 

 up Penzig's „Pflanzenteratologie" our attention is dwawu to 

 „somewhat incomplete pelories connected with meiophylly" 

 suppression of the labellum, synanthy acd dimery as occurring 

 in four species of the genus Calanthe. 



But the species triplicata not being of the number nor having
