NOTES AND EXHIBITS. 207 



Mr. Hedley exhibited a recent conchological work published 

 in Japan, illustrating in colours one hundred Japanese shells, the 

 first Part of "Illustrations of one thousand Shells," by Y. Hirase 

 (1915). The exquisite native art of Japan is here employed in 

 the service of science. 



Mr. E. Cheel exhibited specimens of Digitaria glah'a Beau v., 

 {Panicnrn ylahruiyi Gaud.) from additional localities to those 

 already recorded in these Proceedings (1910, p. 688), namely: — 

 Botany Swamp (W. F. Blakely; January, 1912); Cundletown, 

 Manning River (M. Ahronson; December, 1913); Hill Top (E. 

 Cheel; March, 1914). This grass is of annual duration, but of 

 very little value as a forage-plant, and can be regarded only as a 

 weed, unsuitable as a lawn-grass. Specimens of D. didactyla 

 Willd., {Panicum didactylum Kunth) were also exhibited, for 

 comparison, as this latter species has been previously mistaken 

 for D. glabra, and recorded for Nudgee, Queensland (Queensland 

 Agric. Journal, xvi., p.410, 1906), and apparently for this State 

 also; as, although it has been stated to be common at Vaucluse 

 {vide these Proceedings, 1910, p. 804), three visits to this locality 

 resulted in failure to find it. Mr. F. M. Bailey has corrected his 

 determination of the Nudgee specimen in his "Comprehensive 

 Catalogue of Queensland Plants"(p.603). — Specimens oi Panicum 

 globoideum Domin, from Moree, together with authentic speci- 

 mens of P. Jlavidum Retz., from the Gangetic Plain, North- 

 Western India, collected by Dutliie; and from the Philippines, 

 collected by C. M. Weber (No.l048), were also exhibited to show 

 that P, globoideum Domin, is a vfery different and well marked 

 species. Specimens of P. ramisetum Scribn., and P. Reverchoni 

 Vasey, natives of Texas, from the National Herbarium Collec- 

 tion, were likewise exhibited for comparison, to show the much 

 closer resemblance to, and relationship with P. globoideum than 

 with P. Jlavidum. Hitchcock and Chase, in " Contributions 

 from the U. S. National Herbarium" (xv., p. 22, 1910), have set 

 up a subgenus, Paurochcetiuni, under which both P. ramisetum 

 and P. Reverchoni are included. Mr. F. M. Bailey, Colonial 

 Botanist of Queensland, has recognised P . globoideum a,s, a dis-
