Q6 HOLLICK. 



24. GnapJialhun piirpiireiun L. Not common. Found with 

 G. iiligijiosujn L. in the vicinity of Clay Head. 



With the above additions the Hst now comprises 309 Sper- 

 matophyta and 9 Pteridophyta, but there is no doubt that it 

 could be largely increased if collections were made in the spring 

 and autumn. I was unfortunate in having explored the same 

 region as did Mr. Bailey, at the same time of year, so that I 

 was able to accomplish but little more than to pick up a few spe- 

 cies which he had somehow missed. 



Discussion of the Flora. 



If the flora be now examined as a whole several significant 

 facts may be noted. Many curious lacunae will at once attract 

 attention, as remarked by Mr. Bailey, and not only are species 

 wanting which one might reasonably expect to find, but so also 

 are whole genera and even families. 



For example, the Liliaceae are not represented, and of the Smi- 

 laceae only two species (Smilax rotiuidifolia L. and ^. glmica 

 Walt.) were found in very limited numbers. The Boraginaceae 

 are wanting and, except for a few scattered trees of Nyssa aqiiatica 

 L., the Cornaceae would be likewise. The genera Comics, Vac- 

 ciniuni (excluding the cranberry), Veronica, Mcibomia, Lcspedeza 

 and Baptisia are entirely absent. Only four species of Car ex 

 were found, one Pycnantlieniuin and one Vibtirmiin, while many 

 other species are represented by only a few individuals. Among 

 the species which might be reasonably expected to occur, but 

 which were not seen, may be noted Solaniini Dulcamara L. and 

 V erbasc7un Blattaria L., which usually follow in the wake of 

 civilization ; Hibiscus Mosclietitos L., Vernonia Novcboracensis 

 (L.) Willd., Iva fnitesccns L., Kneiffia linearis (Michx.) Spach., 

 K. piiniila (L.) Spach. and Liniodonun tiiberosiuti L. The ab- 

 sence of the latter would perhaps not be remarkable except for 

 the fact that its usual companion, Pogonia opJdoglossoides (L.) 

 Ker. is quite abundant. 



This list of lacunar could be readily extended by a careful 

 analysis of the flora, but it should also be borne in mind that 

 more thorough search might and probably would reveal the 

 existence of species which have thus far escaped notice.
