On the Development of Arum maculatum 
from the Seed. 
BY 
RINA SCOTT and ETHEL SARGANT, 
With Plate XXV, 
I N April, 1895, a large patch of Anivi maculatum was 
noticed by one of us growing on an open common at 
Instow, in Devonshire. Most of the plants had but one small 
ovate-shaped leaf above ground. There were no mature 
plants anywhere in the neighbourhood. 
On digging some of these up, it was clear that they were 
seedlings, though not very young, but each plant was quite 
distinct from its fellows. One could trace at least two 
dead tubers of previous years in most cases, though the 
plants as yet had not produced the characteristic sagittate 
Arum -leaf. 
It seemed worth while to collect some Arum-fruits, in order 
to study the germination of the seed and generally to test 
under what conditions the plant is reproduced by seeds and 
under what by vegetative budding. 
Amongst the clumps of mature plants with sagittate leaves 
a large number of plantlets with ovate leaves are always 
found. If a clump be dug up, most of these will be found 
to arise by vegetative budding from the mature tuber (see 
Fig. 10 A), while a few are true seedlings.
