ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 199 



Spores of Jurassic Ferns.* — H. H. Thomas records tlie discovery 

 of the spores and sporangia of two common Bathonian ferns, Goniopteris 

 hymenophylloides and Todites Will iamsoni. These structures he describes 

 and discusses. He doubts whether the distribution of the sporangia is 

 sufficient ground for separating Gladotheca Halle from Todites. 



Osmundites.f— J. Schuster describes a specimen of Osmundites found 

 with other fossil woods by H. Carnier near Villa Rica in South Paraguay. 

 He figures and explains the anatomical structure, and gives a diagnosis 

 of the new species 0. Carnieri. 



Xylopsaronius.J — J, Schuster discusses the question of whether 

 Xylopsaronius is the first fern in which secondary wood can be traced ; 

 and is decidedly of opinion that the so-called secondary wood is nothing 

 but the parenchyma of the root-sheath. 



Forbesia cancellata.§ — T. Johnson gives a description and figures 

 of Forhesia cancellata, a new genus and species of fossil fern, or rather 

 of an ancestor of the Filicinese, remarkable for its low organization, 

 namely for its lack of a definite vascular system. The specimens were 

 obtained from the Lower Carboniferous strata near Baudon, Co. Cork. 



- Protocorm of Ophioglossum. |1 — W. J. CI. Land gives a description 

 of a protocorm of Opltioglossum PrlngJei found in Mexico. It is nearly 

 spherical and 9 mm. in diameter, and bears a sterile le;if bh in. long. 

 The scars of former leaves show that it is seven years old. The growing 

 point is sunk in a pit. Rootlets penetrate the cortex in all directions. 

 The protocorm occurred 2 in. below the surface of the soil. The plants 

 of Ophioglossum were found to be in groups of 3 to 10, usually radiating 

 from a larger plant and connecting with it. The protocorm probably 

 has no phylogenetic significance, though its presence and the method of 

 vegetative reproduction may recall Phylloglossum and the Lycopodiales. 



Ophioglossum vulgatum.f — H. S. Holden figures and describes an 

 abnormal spike of Ophioglossum vulgatum. From the vascular bundles 

 he infers that it is an instance of choresis and not of deformity. 



Cyathea multiflora R. Br.** — W. R. Maxon writes on the identity of 

 Cyathea multifiora, the type of the genus Hemitelia R. Br. Robert Brown 

 established his Hemitelia in 1810 upon the following older species : Cyathea 

 multiflora Sm., C. horrida Sm., C. capensis Sm. Concerning G. multiflora 

 there has been little but confusion, almost from the time of its publica- 

 tion. J. E. Smith recorded it as from " Jamaica (ex herb. Banks)." But 

 the original specimen in the Banks collection in the British Museum is 

 endorsed "America merid. R. Shakespeare." Maxon states that this 

 original specimen is evidently part of a rather small frond of Hemitelia 

 nigricans, a Central American species described by Presl in 1849 ; that
