78 SUMMARY OF CURRENT RESEARCHES RELATING TO 



from various Queensland localities. From the Permo-carboniferous of 

 Dawson river he records several species of Sphenopteris and Glossopteris, 

 and describes a new seed, Cycadospermum Dawsoni. It is suggested 

 that Sphenopteris lolifolia, S. alata, S. flexuosa and S. crebra represent 

 different parts or growth-stages of the same frond, which a discovery 

 of the fertile leaves places in the genus Mertensia. Taxoxylon Philpii 

 is a new species from the Ipswich beds, and represents the first taxaceous 

 fossil wood from Queensland. 



Plant-Life in the Sihlthal at Einsiedeln.* — Max Duggeli gives 

 an account of the geographical position, the geology, climatology and 

 flora of this high valley, and the plant-associations which it comprises. 

 The district, which has an area of 12 kilometres, is soon to be sub- 

 merged to form a reservoir in connection with some electric works. 

 Under the heading vegetation, the author gives a list of about 150 

 cultivated plants, followed by a list of those growing wild. The latter 

 comprise nearly 200 species of fresh-water algge, 50 fungi, 75 lichens, 

 130 mosses, 25 vascular cryptogams, and 560 seed-plants. In his 

 description of the cacology of the valley the author distinguishes the 

 following formations : — (a) forest ; (b) bush-vegetation ; (c) schutt- 

 fluren ; (d) meadow-formation (the most important), and the various 

 types comprising it ; (e) water-vegetation, both of flowing and stagnant 

 water, including the plankton ; and (/) culture-formation. The text 

 is accompanied by several sectional diagrams, showing the characteristic 

 plants at the different levels in several of the formations. Another 

 feature of interest is the tabulation which the author gives of the plant- 

 remains found in the peat at various stations in the valley, compiled 

 from a study of numerous sections. There is also a good general map 

 of the district. 



Swedish Saxifrages.f — G. Lindmark gives a somewhat detailed 

 account of the vegetative and floral morphology of the Swedish species 

 of Saxijraga. A short general account containing an organographic 

 key to the species is followed by a special portion, comprising for each 

 species an account of the germination of the seed, the development of 

 the seedling, and the vegetative and floral characters of the adult plant. 

 The paper is well illustrated by five plates ; four of these are double- 

 page. 



Chinese Cyperaceae.J — C. B. Clarke has elaborated this order for 

 Messrs. Forbes' and Hemsley's Enumeration of the Plants of China. 

 The order is well represented in the Chinese flora. Mr. Clarke's 

 enumeration includes a number of new species, especially in the genus 

 Carex, which is by far the largest. There are also various critical notes 

 of some general interest. 



Teratology.§ — K. Schilberszky describes and figures the following 

 examples of teratology : twin-bulbs in an onion (Allium Cepa), the
