HiLDEBEAND. — Uebcr ein Chroolepus mit Zoosporenbildung, von 

 Dr. Hildebrand. Bot. Zeit. 29 March, 1S61. Vol. xix. p. 81. 



Dr. Hildebrand gives an account of a species of Chroolepus 

 considered by the author to be new, but which he states to have 

 been pronounced by Kiitzing to be a form of the protean Chroo- 

 lepus aureum. The author gives an account of the production 

 of zoospores from flask-shaped cells which appear to be some- 

 times terminal, sometimes lateral. The zoospores do not difter 

 materially from those described by Caspary in the Flora for 

 1858 as produced by 0. aureum var. tomentosum. The author's 

 experiments tend to show that warmth and moisture are neces- 

 sary for the production of the zoospores, but that the presence 

 of light is not essential. He observed that as a rule the number 

 of zoospores is always either 32 or 61;. He observed the com- 

 mencement of their germination by self-division. Tlie author 

 proposes " lageniferum" as the specific name on account of the 

 shape of the zoosporangia. The plant occurred on the bark of 

 climbing plants in the Palm House of the Botanical Garden at 

 Bonn.
