sent it to Grisebach. Prioria is one of the largest trees of Jama- 

 ica, sometimes attaining a height of ninety feet, and is a member 

 of the senna family. So far as is known, this tree is found only 

 on two estates in Jamaica, and grows at an elevation of from five 

 to six hundred feet. This species is characterized by having a 

 one-seeded legume, which is indehiscent. The genus Pi'ioria is 

 reported to be represented also in the Republic of Panama. 



Dr. Murrill displayed photographs and colored drawings of 

 several of the larger local fungi. He also explained reproduc- 

 tion of colored drawings by the four-color process. This process 

 seems to be the most satisfactory for representing fungi in colors. 



Mr. Nash exhibited a living plant of Dendrobimn Coelogyne, 

 a rare orchid from Burma, which has just flowered in the con- 

 servatories of the New York Botanical Garden. Specimens of 

 Coelogyne and of other species of Dendrobiiini were also shown to 

 illustrate the characters of these two genera. While the tiowers 

 of Dendrobium Coelogyne resemble those of a Dendrobiiini, the 

 habit is that of a Coelogyne.

 apparatus constructed by Professor Bose for the purpose of
