the frond is held to the light there is seen a 



clear line along each side of the axis of the 



pinna, between it and the pinnules, a line quite 



absent in the case of acideatum. Further, with 



regard to the pinnules of angulare, it is also 



pointed out by Dr. Scott that they possess a 



characteristic rounded lobe at the lower outer 



extremity of the triangle, a lobe absent in 



aculeatum. 



o. In aculeaiuiii the ijiiince of the lower part of the 



rachis gradually diminish in size downwards till 



near its lower end ; 



in angidare the pinncc stop abruptly, and somewhat 



higher up the stipes, or part of the stem below 



the pinnce. 



4. In both species, while the stipes is clothed with 



membranous, chaffy, reddish-coloured ramenta or 



scales, these scales, in the case of angidare, are 



larger, shaggier, and more copious than in 



acideatum. 



1 have to apologise, not only for the length of this 



" Note," but also for the fact that so much that is stated 



in it is common knowledge, still I hope it may afford 



interest to some, and that it may also stimulate a desire 



to study those nature-forms to which we have been 



referring;.
