species, which more careful examination would readily show were quite distinct. The points 

 from wliich characters are taken are the roots and leaves; form and mode of attachment, 

 by the middle or base, of the scales on the scape and the bracts at the origin of the 

 pedicels; the length of the pedicels in comparison with the bracts and flowers; the form 

 and she pf the calyx lobes, whether acute, blunt, or orbicular; the form and colour of 

 the corolla, the relative size of the lips to each other and to the length of the spur; the 

 ipur, whether long or short, pointed or obtuse; the capsule, whether ascending or droop- 

 ing, longer or shorter than the calyx, compressed or globose; and lastly the form of the 

 seed, whether globose, oblong, or compressed, elliptical, or ovate anS pointed at one end, 

 smooth) or reticulated, spirally furrowed or glochidiate. 



From this enumeration of the points whence distinctive characters may be drawn it 

 is obvious they furnish an ample store to ensure their ready discrimination in all cases 

 where carefully examined. And having subjected most of those in my collection to such 

 an examination I find, thouorh far from perfect, that it contains as many species as 



consider my collection imperfect, because I have 

 recently learned how to examine a Utricularia, and feel certain that I have 

 heeded many species on the supposition that I had already specimens in my Herbarium. 

 In collecting specimens care ought to be bestowed on getting them as perfect as possible, 



especially as regards the flower and fruit. This last should never be nedected, as the 

 eeed, though ' ...--.... h ^
