I have specimens of Centaurea Cyaniis^ L., which I obtained from 

 a garden a few years since, and which exhibit this same sort 

 of prolification — the elongated axis bearing a second capital um very 

 slightly smaller than the primary one. At the same meeting of the 

 Club, Dr. Thurber, after remarking that double flowers are rare in 

 a state of nature, announced that he had recently received from Con- 

 necticut, specimens of Nesacaverticillatay H. B K., in which all of the 

 flowers were double ; and another member* reported that he had ob- 

 served, during the preceding spring, the same thing in a specimen of 



if^ 



In the note before alluded to, Prof. 



Harvey states that he had seen a plant of some species of Alliurn in 

 wdiich a stamen, in a flower otherwise normal, was replaced by a 

 bulblet ; and in another flow^er, one of the stamens w^as replaced by 

 a perfect flower. He says further : '' An ear of corn, which has 

 grown wrong side out, is in my possession. The ear has the form 

 of an inverted truncated cone, bearing the kernels on the walls of 

 the hollow. The cob has a smooth exposed surface, and a texture 

 somew^hat more compact than that of the cob of normal ears." *This 

 is perhaps a case of eversion of the axis, the termination of the lat- 

 ter becoming hollow^ through a disproportionate growth of the outer 

 as contrasted with the central parts of the rhachis, and the female 

 flowers and the seeds bein^ borne on the walls of the tube thus formed.

52. Publications. — i. Preliminary List of 



without cultivation in Alabama, from the collections made by Eugene 

 A. Smith, Tuscaloosa, and Charles Mohr, Mobile, compiled by 

 Charles Mohr; 629 genera, ending with ^£r^//^ Caroliniana, y!\\\6..\ 

 containing about 1,600 species and varieties, of which something like 

 half are strangers to our region. We notice that Mr. Smith is the auth- 

 ority for Asplenium ebenoides j it would be interesting to know w^hether 

 he found it in the locality discovered by Miss Tutweiler, or has a 

 new station for this disputed species. This list is preliminary to a 

 complete catalogue of the Flora of Alabama to be published here- 

 after in one of the Reports of the Geological Survey of the^ State. 

 Those who have authentic specimens of plants not in the list are 

 invited to communicate them to Messrs. Smith and Mohr. 



2: Porest Trees of North America. — It is proposed to join to the 

 Report on the Forest Wealth of the United States now in prepara- 

 tion for the Tenth Census, a Catalogue of the Forest Trees of North 

 America, wdth special reference to their geographical distribution 

 and economic properties and uses. To facilitate the collection and 

 preservation of such information Prof. Chas. S. Sargent, Urookline, 

 Mass., issues this preliminary catalogue, wath blank pages for field 

 notes and corrections. Any information which will serve to make 

 the final publication more exact and complete will be gratefully 

 received and duly acknowledged. Almost every botanist has it in 

 his power to contribute something. Information on the following 



points is particularly needed. 



1. The extreme geographical range of any species. 



2. The region and elevation where any species is prmcipally multi- 



plied and reaches its greatest perfection.
