Nov. 4. — The Lord Bishop of Norwich, President, in the Chair. 

 Read a memoir "On the Amhrosinia ciliata of Roxburgh." By 

 the late William Griffith, Esq., F.L.S. &c. Communicated by R. 

 H. Solly, Esq., F.R.S., L.S. &c. 



In this paper, written at Calcutta in the year 1835, Mr. Griffith 

 enters into a lengthened examination of the characters and deve- 

 lopment of the singular plant above named, to which he states his 

 attention to have been first directed by Dr. Wallich, who was pre- 

 viously acquainted with many parts of its structure. It forms, in 

 conjunction with Amhrosinia spiralis, retrospiralis and unilocularis 

 of Roxburgh, a genus of Aroidece, for which Mr. Griffith regrets his 

 inability to adopt the highly appropriate name of Myriohlastus pro- 

 posed by Dr. Wallich, inasmuch as M. Fischer had previously pro- 

 posed the generic name of Cryptocoryne for the Ambr. ciliata and 

 spiralis of Roxburgh, together with Caladium ovatum, Vent., in which 

 latter, however, the structure of the fruit, as described by Rheede, 

 appears to be somewhat different. 



The following are the amended characters of the genus, proposed 

 by Mr. Griffith :— 



Cryptocoryne, Fisch. in Schott and Endl. Mel. Bot. fasc. 1. p. 6. 

 Spatha tubo brevi ad apicem septo obliquo incomplete semipartito ; limbo 

 elongato. Spadix basin versus ovariis cincta, medio filiformis nuda, 

 supra antherifera, apice conico nudo calloso spathae septo pilei instar 

 tecto. ^/i^^er^biloculares, transversim dehiscentes. GlandulcB n\x\\?e. 

 Ovaria 5 — 7, coalita ; styli nuUi ; stigmata 5 — 7, obliqua. Fructus nu- 

 dus, 5— 7-locularis (in unic^ specie 1-locularis) ; dehiscentia septicida.
