BäDOUSE, H., Ein eigenthümlicher Auswuchs an einer 

 Buche. (Schweiz. Zeitschr. für Forstwesen. 1903. Jahr- 

 gang LIV. p. 87—89. Mit Abbildung.) 



Der abgebildete Auswuchs besteht ausschliesslich aus Rinden- 

 substanz, besondeus aus Kork und ist reichlieh mit Sklerenchym durch- 

 setzt, er erinnert einigermassen an eine Blume mit 6 Kronblättern, von 

 denen die 3 unteren stärker entwickelt sind als die oberen, aus der 

 Mitte erhebt sich ein zapfenartiges Gebilde. Verf. spricht die Vermuthung 

 aus, dass dieser merkwürdige Auswuchs als eine hypertrophe Wucherung in- 

 folge Entgipfelung des Stammes zu deuten sei, er befindet sich genau an der 

 Ursprungsstelle zweier Wurzeln. Die betreffende Buche stand an einem 

 steilen Westhange im Walde La Tete de Massillon der Gemeinde 

 Les Planches-Montreux (Vaadt) bei 750 m. M. Rikli. 



Barton, Ethel g., List of Marine Algae with a note on 

 the fructification of Halimeda. (Report to the Govern- 

 ment of Ceylon on the Pearl Oyster Fisheries of the Gulf of 

 Manaar, by W. A. Herdman, D. Sc. F. R. S. pubüshed 

 by the Royal Society 1903. Supplementary Report II. p. 163 

 — 164. 3 figs. in text.) 



A list of 25 species, the most interesting of which is Halimeda 

 gracilis, since this is here for the first time recorded in fruit. Sporangia 

 are borne on sporangiophores, as in H. Tuna, which form a continuation of 

 the filaments composing a branch of the central Strand. These Strands 

 emerge at the upper margin of a point and form tuits of sporangio- 

 phores. Each filament branches dichotomously and forms two sporangio- 

 phores, from which the sporangia emerge all round and form a kind of 

 loose raceme. E. G. Gepp (nee Barton).

Gracilaria confervoides (L.) Grev. collected at M a 1 1 ap oise : t, 

 Massachusetts constitutes the first definite record for this species on 

 the Atlantic coast north of the Carolinas. 



Actinococcus peltaeformis Schmitz , parasitic on Gymnogongrus 

 Norvegicus, is reported from two stations on the coast of Maine. 

 Codiolam pusillum (Lyng.) Foslie is reported from Cutler, M ai n e, the 

 plants in all stages from the typical European form to the Massa- 

 chusetts form distinguished by Foslie as forma Americanum. Spiro- 

 gyra decimina triplicata Collins n. var. is described from Somerville, 

 Massachusetts. Note on the relationship of Plectonema Battersii 

 Gom., which is reported from an additional Station in Maine and from 

 Marblehead, Massachusetts. 



Microcoleus tenerrimus Gom. was found associated with the com- 

 moner M. chthonoplastes at Southwest Harbor, Mount Desert Is- 

 land, Maine. Xenococcus A>r«m'Hansgirg, described iromBohemia 

 and later distributed from East Africa, was found to be abundant in 

 a high tide pool at Cohasset, Massachusetts; the first Ameri- 

 can record. William R. Maxon.
