Grandidens, Moore. (Fig. 52.) — The present very interesting 

 and distinct variety was found in Devonshire by Mr. E,. 

 Penwell, and brought under notice by Mr. Hodges, of Chel- 

 tenham. This is another of those dwarfish forms of Polystichum 

 angiilare, having narrow lanceolate fronds. In a species so 

 subject to variety as the present Polystichum, there are varieties 

 which run into each other and mingle their several peculiarities, 

 in a manner that makes it difficult to determine to which 

 these varieties should belong: these of course are not distinct 

 enough to warrant being figured and described. Sub-varieties 

 of certain forms are numerovis, as, for instance, those of the 

 variety CHstatum; and, although there is occasionally a 

 marked difference between them, nevertheless there is not 

 sufficient distinction, and therefore they are passed over with 

 merely a remark. Another class of varieties are also discarded.
