128 SUPPLEMENT. 



For fine specimens of this distinct and beautiful species I am indebted to its discoverer 

 Mr. Ashmead of Philadelphia, who sent them to me marked with the specific name here 

 adopted.

 peduncles, borne by the lesser branches, ovate or sub-urceolate, thin walled, without

3. NiTOPiiYLLUM Fryeanum,; frond sessile, full-red, nerveless, thickish, deeply divided 

 into many cuneate lobes, which are again vertically cleft, the segments rounded, frequently 

 crisped at the margin, specially towards the base, the sinuses narrow ; fruit ?

I propose this species with much hesitation, having as yet seen only very imperfect 

 specimens, which I know not how to dispose of but by giving them a local habitation 

 and name. Two specimens are before me ; one faded, tlie other in a better state of 

 preservation, but neither in fruit. The frond is about 3 inches long, and 4 in lateral 

 expansion, and is deeply divided into 4 or 5 principal segments which are broadly 

 cuneate, and each again partially cloven into 4 or 5 lesser, vertical segments. The 

 margin towards the base of the lobes is crisped or undulate ; in other parts it is plane. 

 The lesser lobes are somewhat crenate or sub-lobulate, and all the tips are rounded, and 

 the axils or sinuses very narrow. The substance of the membrane is thickish ; the 

 surface- cells large and tessellated ; the cells of the interior appear also to be of large 

 size, and quadrate, but the specimens examined have been too much squeezed in the 

 process of drying, and their cells are consequently broken and diflicult to examine. No 

 traces of veins in the specimens seen. More perfect specimens must be had before this 

 species can be considered as other than provisional. 



Fragments of one or two other Nitophylla have reached me from the Pacific Coast, 

 but not sufiiciently perfect to warrant me in naming them.

 a fan-shaped, many times dichotomous, rose-red frond ; lucinite linear, with rounded
