to the food of the Hawaiians. Of these not more than 40 are com- 

 monly used, the others being insufficient in quantity. Each edible 

 limu häs its own distinctive native name, combined with the generic 

 name limu either as an adjective or as a sufifix. 



The subject is treated principally under the following heads: 

 Methods of gathering limus; native methods of preparing and ser- 

 ving limus for food; the most populär varieties of limus; methods 

 of preserving seaweeds; the limus most abundant and easily gathe- 

 red; native methods of cultivating limus; value and amount of 

 native seaweeds sold in Honolulu; value of seaweeds imported by 

 Orientais into Hawaii; use of limus for medicines and incantations; 

 Chemical analyses and comparative food values of seaweeds; amount 

 of gelatin or glue found in Hawaiian algae; Hawaiian limus for 

 making agar-agar for culture media; further utilization of Hawaiian 

 seaweeds for food, gelatin, farina glue, and mucilage; methods of 

 preparing jellies, soups, etc.; comparison of Hawaiian and Japanese 

 species of economic algae; possibility of cultivating native, Japanese, 

 Java, or Cej'-lon algae in favorable localities on the Hawaiian or 

 American coast; general summary of the possibilities of the seaweed 

 industry. 



Finally, there follows an enumeration of the scientific names of 

 the species of edible limu of Hawaii, with the corresponding native 

 Hawaiian names in opposite columns. Maxon. 



Hasselbring, H., Gravity as a form-stimulus in Fungi. (Bot. 

 Gaz. XLIII. p. 251—258. 1907.) 



Horizontal orientation of the pileus is brought about by two 

 methods: 1) In stalked froms the stalks are negatively geotropic and 

 by their curvature bring the pileus into the horizontal position; 

 2) In sessile forms the orientation is brought about by growth in 

 the trama-plates, which as Sachs has shown , are positively geotropic. 

 Klinostat experiments were performed with forms from a number of 

 families. The main species used were Polystictiis cinnaharimis, Schi- 

 sophyllum commune, Lentinus lepideus, and species of Coprinus. It 

 is concluded that gravily has no apparent effect on the Organization 

 of the hymenophore, but it has a marked influence on determining 

 the configuration of the fruit-body of some forms. The effect is most 

 marked in most primitive forms, therefore the most plastic forms 

 are to be found among the most primitive. When the force of gra- 

 vity is removed from Polystictiis the fruit-bod}' assumes the resupi- 

 nate or pulvinate form characteristic of the simplest Basidiomycetes.

11. Ueber den Bau des Stieles von Puccinia Geranii sylvatici 

 Karst. Der Stiel hat unmittelbar unter der Teleutospore eine Quer- 

 wand, welche die erste bei der Sporenbildung entstehende Wand 

 darstellt. (Dem Referent erscheint die obere kleine Stielzelle als 

 sterile Sporenzelle; die Art wäre somit eine Uebergangsform zur 

 Gattung Phragmidiinn). — 12. Ueber eine neue Taphridiuin- Avi,
