genera. Urginea he regards as a good genus, separable from all the rest 
by its uniseriate discoidal seeds, and holds that a great deal of the confu- 
sion that has arisen in the tribe has been caused by its species being 
separate genus apart by themselves.——‘ Note on the Structure of the 
Flowers of Cochliostema.” By M. T. Masters, M.D. The author de- 
sired to correct the view which he published a few years since of the 
structure of the andreecium in this very singular Commelynaccous genus. 
rom his examination of the fully-developed flower he had been led to be- 
lieve that there were nine st , the inner three at the posterior part of the 
flower, with the remarkable spiral anthers, two vertical and one horizontal ; 
then three other bodies, believed to be staminodes, two anterior and one 
posterior, and an indication of an inner row of three more. An exami- 
nation of the young condition of the flowers has, however, shown that 
the single posterior apparent staminode is developed long subsequently to 
the other two, and is evidently merely an adventitious production; there 
are, therefore, only six stamens.——-* On Mesotus celatus, Mitten.” By 
S. O. Lindberg. Specimens were received by the author from Dr. Knight, 
of Auckland, N. Z., and the plant was considered to be probably a mem- 
ber of the Dicranee. “On a hybrid Vaccinium, between the Bilberry 
(F. Myrtillus) and Cowberry (VF. Vitis-Idea).”” By R. Garner. The 
specimens, which were collected late in the year, in Staffordshire, were ex- 
hibited. The general opinion elicited by their examination was, that they 
were a luxuriant state of V. Vj itis-Idæa, due to situation, rather than a 
ybrid.—— * On the Marine Algee of St. Helena.” By G. Dickie, M.D.
