10 TWENTY-FIFTH REPORT ON THE STATE MUSEUM. 
full grown plants with mature fruit on the fourth. In noinstance 
were mature fruiting plants found on internodes younger than this. 
On the other hand, however, a few rather large and slightly 
branched plants were found on the fifth and stxth internodes. 
Thus it is evident that this plant requires three seasons for its 
entire growth and the perfecting of its fruit. In the first season 
the plant emerges from the bark, in the second it forms its flower- 
buds, in the third it blossoms, the male plants perishing soon after, 
the fertile or female plants enduring until the ripening of the fruit 
in autumn. It is possible that the seeds may sometimes germinate 
on internodes older than those next to the young shoots of the sea- 
son or else that the plant may sometimes continue longer than the 
third season as is indicated by the few specimens on the fifth and 
sixth internodes. I thought I detected a slight curvature and 
prolongation of the pith or central portion of the stem below the 
apparent base of the stem, whence it is not improbable that there 
is a subcortical or creeping stem which advances with the growth 
of the branch from year to year, sending up successive crops of 
plants. This would explain most readily the great abundance of 
plants and their regular gradation on successive internodes, but [ 
tailed to trace any such subcortical connecting stem. 
How are the seeds disseminated? Having visited the locality of 
the plant one month subsequent to its discovery in September, I 
was a little surprised to find almost no fruit-bearing specimens left. 
In their stead were here and there little heaps of fragments of 
stems, fruit and seeds all intermingled, adhering to each other and 
to the branches by the viscid coating of the seeds, in such a man- 
ner as to suggest the idea that some insect or bird had been among 
the plants, breaking them down and perhaps feeding upon the fruit. 
I have in no instance found both the male and the female plants 
on the same branch, nor even on the same tree. If such aremark- 
able separation is constant it would be interesting to know the 
cause of it.
