365. ACETABULARIA CRKNULATA, Lmx. Florida. — For the his- 

 tory of tlie development of this genus we are indebted to Woronin, 

 whose researches, however, were brought to an end befoi'e he had seen 

 the dispersion and germination of the spores. Dr. E. Palmer, while 

 at Key West last summer, collected specimens of this plant in fruit, 

 and in some of them the radiating cells at the summit had separated, 

 giving the appearance seen in the genas Poli/phi/sa. It might be asked 

 whether P. Clifloni, Harv., which is figured in fruit ia the Phyco'ogia 

 Australica and described as rare, is any thing more than the fruiting 

 state of some Acelabularia. i 



VALONIACEiE. 



366. Cham^doris annulata, Mont. Key West. 



367. Penicillus dumctosus, Dne. Florida. 



368. Penicillus capitatus, Lmk. Key West. 



369. Penicillus Piicenix, Lmk. Florida. 



370. Blodgettia confervoides, Harv. — This plant is certainly 

 worthy a most careful study. The figure of Harvey is most extraor- 

 dinary ; and, if correct, this plant deserves, at least, to be the type of a 

 new order. As M- Bornet suggests, however, the spores ? are parasitic 

 unicellular algse. The Blodgettia itself is probably nothing more than 

 a Cladophora nearly related to C. prolifera. 



371. Anadyojiene flabellata, Lmx. Key W^est. 



372. DiCTYOSPH^RiA FAVULOSA, Dne. Key West.
