lular body (quoted from Goxrsz1). This development of threads 
from prothallia is promoted by breeding the plants in faint light. 
But all the cases cited above are more or less pathological, 
whereas in Taeniophyllum proliferum the reversion to the pro- 
togenic form is a hereditary property, playing an important 
part, side by side with the seminal reproduction, in the propa- 
gation of this plant.

This interesting species was discovered by Miss C. C. Rern- 
vAAN in a village naar Bandung. The plants grew on the 
hanging branches of a big tree in a grave-yard. At first the 
plants displayed nothing extraordinary; a couple of long slender 
roots, a young flower-stalk on which fructification had already 
taken place as is usual with this species, and on which flower- 
buds occurred. The two plants were placed on a young Ficus- 
tree in my garden at Bandung, and there they grew slowly but 
regularly. After a couple of months a flower-stalk and some small 
roots developed at the extremity of some of the earlier roots. 
This of course aroused my attention, but at first I supposed it 
Was a case of an occasional production of advententitious buds 
on the roots, which would be remarkable enough in an orchid. — 
On removing to Buitenzorg I took the two plants along, 
preserved in alcohol, but the material was not sufficient to 
allow my making an inquiry into the question of gemmation. 
Dr. J. J. Smirn kindly examined them for me, and informed me 
that they belonged to a new species of Z'aeniophyllum, to which 
he gave the above name. 
Miss Reinvaan looked for them once more in she’ same : 
finding-spot and succeeded in collecting more material. Part of — 
these I put on a little tree in my garden, where they now grow 
and flourish well and continue forming buds. Also among the 
ed on the finding-spot there were 
several plants bearing ‘adventitious buds. ‘This formation mS
