Glabrous or pubescent, but not glandular. When conspicuously downy it is T. pubescens Nuitt. The achenia are rarely pubescent. So far as I have been able to observe, glandular and non-glandular trichomes never occur on the same plant, nor have I seen any glandular specimens with the characteristic stamens of T. polygamum, so that the presence of glands appears to be characteristic of T. purpurascens, so far as these two species are concerned. Where no stamens occur it is impossible to identify fertile plants with certainty unless this character can be utilized, and it must then be used only as a positive character, since glabrous or pubescent forms occur in both species. In T. purpurascens a variety can not conveniently be based on it, for several other species of the genus (e. g. T. sparsiflorum) include both glabrous and glandular forms, not separable by associated characters. No good reason exists for separating T. purpurascens into two species (revolutum and dasycarpum) as has been done by Lecoyer ; nor, in the opiniion of Dr. Gray, is there sufficient doubt as to the plant intended by Linnaeus to warrant the rejection of his name in this instance, though this is necessary in the case of T. polygamtim. Specimens occur both in the north and south which resemble T. dioicum in having very thin glabrous (rarely sparingly pubescent) pale leaflets rounded and with 7 to 9 round lobes at the apex, but with the fruit, as in these species, i. e., thin-walled, stipitate, 2-edged and wing-nerved (not subsessile, thick-walled, terete and deeply and evenly grooved). It is doubtful whether these forms should not be regarded as hybrids, and cases of the simultaneous flowering of T. dioicum and either of the late species should be noted.-WM. TRELEASE. The Brothers Tulasne.-It is but a few months since the botanical journals announced the death of Charles Tulasne at Hyeres in the south of France, on August 21, 1884, and we are now called to mourn the death of his elder brother, Louis Ren6 Tulasne, who died at Hyeres on December 22, 1885. In their lives and botanical work the two brothers were so intimately associated that botanists have almost come to use the name Tulasne as representing a single person. They were so modest and reticent with regard to themselves that few details of their lives could be learned even by their associates. The older brother, Louis Rend, was born at Azay-le-Rideau, Indre-et-Loire, September 12, 1815, and studied law at Paris. His first botanical work was in coninection with Auguste St. Hilaire in the preparation of his flora of Brazil. In 1842 he was appointed aide-naturaliste at the museum of the Jardin des Plantes, and, in 1854, he was elected to the Academy as the successor of Adrien de Jussieu. About 1864 his health failed and he was obliged to retire from active service at the museum. His brother Charles was born at Langeais, Indre-et-Loire,
