Masters’ Vegetable Teratology ') it is stated that this devia- 
tion, though of rare occurrence, is especially observed in aérial 
roots of tropical plants, as Aérides crispum, Phalaenopsis Schille- 
rianum, Cactus, Epiphyllum and some Dioscoreae.

Fig. 28 is intended to illustrate the occurrence of two op- 
posite spathae of the spadix of Anthurium cristallinum, instead 
of one. According to Penzig II p. 440 the occurrence of two 
spathae has already been observed in Anthurium Andraeanum , and 
many times in 4. Scherzerianum. 
The next figure 29 shows the fasciation of the inflorescence 
of Ledenbergia rosea aenea (fam. Phytolaccaceae) , as it developed 
in the garden of Buitenzorg. The splitting up of the growing 
point has proceeded very far and explains how the originally 
round axis has been flattened to such an extraordinary degree. 
When the seeds have come to maturity, the heredity of this 
fasciation could be easily tested. The numerous specimens which 
I brought to Europe in 1892, and the intelligence which in 
1894 I received from Mr. Smith about fresh collections render 
it probable that an investigation as above suggested would 
lead to a confirmatory result. 
Lactuca sativa (fam. Compositae) Fasciation of stem and in- 
florescence. 
Spilanthes oleracea (2) (fam. Compositae). One specimen showed 
a number of capitula clustered together. 
One morning when at work in the visitors’ laboratory, I 
got from Mr. Treub a stem of Musa, of which a much reduced 
drawing is given in fig. 30. The deviation concerns the spot
