Jalapa of Linnaeus and Willdenow, or Ipomcea macrorhiza of Mi- 

 chaux, a native of Vera Cruz. It has recently been proved, however, 

 from various sources, to be the plant now under notice, which grows 

 in the hill country near Jalapa, in Mexico, at a height of about 6000 

 feet above the level of the sea. The plant was first sent to the Edin- 

 burgh Botanic Garden by Dr. Christison, who received it from Dr. 

 Coxe, of Philadelphia, and has flowered several times in a cold frame. 

 It belongs to the natural order Convolvulaceae. The genus Exogo- 

 viiini has been separated from Ipomcea by Choisy, on account of its 

 exserted stamens. Specimens of the recent plant were exhibited. Dr. 

 B. also described Stenocarpas Cunninghaini of Hooker, and exhibited 

 a fresh specimen in flower. This plant has been long known in gar- 

 dens under the name of Agnostus sinuaius. It is a small evergreen 

 tree, belonging to the natural order Proteaceae, sub-order Folliculares, 

 and tribe Grevilleae. It was found by Allan Cunningham on the banks 

 of the Brisbane River, Moreton Bay, and is remarkable for its umbel- 

 late inflorescence, and showy orange-scarlet flowers, with reflexed and 

 sub-secund segments of the perianth. The plant was first introduced 

 into the Royal Gardens at Kew, whence it has been distributed over 

 the kingdom. It has flowered this season for the first time in 

 Britain. 



2. Remarks on a Pyrola found in Lancashire, by Mr. Kenyon. 

 Specimens of this plant, which is considered by its discoverer as a 

 new species, and which he proposes to call P. maritima. in allusion 

 to the localities in which it is generally found, were shown to the 

 meeting. It is nearly allied to P. rotundifolia^ from which it may be 

 distinguished by its size, the form and length of its sepals, and length 

 of the stamens. Some excellent botanists who have examined it, are 

 of opinion that it is only a variety of that species. 



Mr. Wra. MTvor, of the Kew Gardens, sent specimens of an Oro- 

 hanche, considered by him to be O. liicornm, Braun, gathered on 

 Epsom Downs ; also Hormospora niutahilis, from Studley, Yorkshire, 

 and Thorea ramossissima, from the Thames, near Walton. 



A series of beautiful photographic delineations of various forms of 

 leaves, prepared by Mr. James Lumsdaine, jun., of Lathallan, Fife, was 

 exhibited, and an account read of the process by which they were 

 obtained. 



There was also exhibited a collection of Ruhi from the Rev. A. 

 Bloxam, of Twycross, Leicestershire, containing some new species 

 and varieties.
