of the same natural family, agreeing with it in the singular structure of the capsule, seeds, 
and filaments, still, the form of the leaves is so different, that no difficulty will be found in 
distinguishing the two plants. 
Although I have called the little spherical bodies, observable upon the stems. Gemma, 1 
Ought to remark, that they are quite of a different nature from those minute particles, (to 
which I have given the same name) that are produced upon the extremities of the stems or 
leaves of J. bicuspidata, J. exsecta, J. ventricosa, &c. ; these having no apparent internal orga- 
nization, while the former are composed of cellules as large as those of the leaf. Similar Gemma 
(if such they may be called) are found on J. minutissima and J. hamatifolia , and, probably, 
also (though I have not yet been so fortunate as to meet with them) upon J. serpyllifolia.

of the plant would have prevented its appearing otherwise than as a small, green, shapeless mass.
