It evident, as T think, that the latter was such as the former would 

 produce if cultivated. If guessing be allowable, I would say- 

 that the originals of the European cultures emanated from near 

 the Atlantic coast, in rich soil, alluvial deposit, just such as is 

 most favorable to a very vigorous growth ; that to all intents and 

 purposes they differ not from what is recognized by us as R, In- 

 ctda [R. huniilis, var. lucida). 



Another problem, perhaps still more difficult, is to know what 

 are the actual relationships, between eastern forms oi the humilis 

 group and those of the south and w^est. Are they in reality but 

 one polymorphous species, the transitional forms due to difference 

 m location and climate — in a word — to environment ? Or are they 



distinct species, the intermediate forms hybrids?* To the solu- 

 tion of this problem I bespeak the indulgent aid of all botanists, 

 especially the Eastern, reminding them of the possibility of cross- 

 ing between species and the production of fertile hybrids; and 

 that environment modifies all forms but in all probability the most 

 markedly those of hybridic origin. 



Botanical Notes. 



Corrections. There are two mistakes in the May BULLETIN. 

 I rofcssor Bailey's report of the blooming of Houstonia cccrzdca on 

 February 26th, is just a month earlier than what he intended to 

 report, March 26th. In the enumeration of Richmond County 

 plants Aster cordifolins, V2.x. glabratus, should read var. Ic^vigatiis, 

 under which name it was published by Professor Porter in the 

 March issue; the other name had been used in manuscript and 

 was inadvertently retained when Mr. Holh'ck made up the copy. 



Pinus rigida. Mill. At South Amboy, New Jersey, a short 

 tune ago, I noticed some young shoots about sixteen inches high 

 growing from the stump of a pine about six inches in diameter. 

 While examining the shoots, T was interested to note that the 

 primary leaves were about one and a quarter inches in length, and 

 horn tlieir axils grew fascicles In some cases of four leaves, 

 though the majority of the secondary leaves were in threes. 



At Cliffwood, New Jersey, I have since found a small pine
