oi the lobes seem to have been recurved. It is also pointed 

 out that Sphenopteris lolifolla Morr,, vS. alata Stenb., >S. 

 flexiwsa Mc. Coy, 6". crebra T, Woods probably represent 

 different portions or stages of growth of the same frond. 



From the Ipswich beds (Trias-Jura) two new species, 

 Palissya gracills and Oleandridlum jaciili, are described, as 

 well as a number of additional identifications. 



From Upper Cretaceous beds, a new species, Ficus siib- 

 _g(jepperti is recorded, and somewhat doubtful identifications 

 with Magnolla and Marsilea have been made; the latter on 

 the occurence of certain fruit-like bodies resembling the 

 sporocarps of that genus. 



The petrifactions from the Ipswich beds occur in a bed 

 of volcanic tuff. Taxoxylon Philpii is a new species, and is 

 the first fossil wood of the Yew section of the Coniferae 

 described from Queen sland. Another specimen is doubtfully 

 referred to the genus Araucarloxylon. Arber (Cambridge). 



Cousins, H. H., Grass Oils. (Bulletin, Department of Agri- 

 culture Jamaica. Vol. I. 1903. p. 53 — 56.) 



The results of experiments made in Jamaica with Andropogon 

 Schoenanthus, and Andropogon Nardiis are reported. 



Andropogon Schoenantltns, the „fever grass" of Jamaica gren 

 well but gave a vey disappointing field, only about 4 oz. per cwt. of green 

 grass. The best results were obtained with freshly cut grass cut into 

 lengths of about 6 in. before distillation. The oil was of lower specific 

 gravity than the oil obtained in previous similar experiments in Trini- 

 dad and laevo-rotatory instead of dextro-rotatory. 



Andropogon Nardus, the „citronella grass" of Ceylon, groun at 

 the Hope gardens Jamaica yielded 11,6 oz. of oil per cwt. of fresh 

 grass. Compared with the oil obtained in the Trinidad experiments it 

 was of lower specific gravity and higher dextro-rotation. A further tech- 

 nical report is awaited. W. G. Freeman.

Hart, T. H., The preparation of essential oils in the 

 West In dies. (West Indian Bulletin. Vol. III. 1902. p. 171 

 — 178.) 



A populär paper drawing attention to the neglect of this subject in 

 the West Indies in the past, and offering suggestions for its develop- 

 ment in the future. 



Lemon grass (Andropogon Schoenanthus) has long been known in 

 the West Indies, and Citronella grass (A. Nardus) has recently been 

 introduced from Ceylon.
