latter to show that it belonged to a small group of mosses, § Urocladium of the 

 genus Pinnatella Fleisch., {Porotrichum spp. auctorum), consisting of some half 

 dozen species confined to the southeastern region of Asia (India, Malay Archi- 

 pelago, Tonkin, Formosa, Japan), and especially characterized by an intra- 

 marginal border or band of elongate cells, such as is found in a very few groups of 

 mosses only {Calymperes, Fissidens, particularly). The Reuverian moss is 

 scarcely distinguishable from P. alopecurioides (Hook.) Fleisch., except in the 

 shorter nerve (35-40^1 wide) and the leaf-cells slightly larger and with a pro- 

 nounced tendency to be elliptical. These characters are probably quite sufficient 

 to indicate a specific difference, but the relationship is close, and the fragment 

 bears out in an interesting way the indications given by the rest of the plant 

 remains. 



"The second from- Reuver is perhaps still more interesting. It is a species of 

 Mnium of the § Trachycystis, represented at the present day by two species 

 only, both confined to China (including Saghalin and the Amur region) and 

 Japan. It differs however from both of these, and in conjunction with Mons. 

 Cardot, who has kindly examined it, I propose the following name for it: 



"Mnium antiquorum Card. & Dixon, sp. nov. A M. microphyllo Doz. & Molk, 

 differt cellulis minoribus, parietibus magis incrassatis, atque foliis limbo incrassato 

 bistratoso circumscriptis; a M. flagellari Sull. & Lesq. proximo foliis minoribus^ 

 irregulariter, obscure, simpliciter dentatis, nec spinulis bigeminatis armatis."

THE MOSSES OF THE PECH CATALOGUE— MISSOURI 



B. F. Bush 



It is just a half a century since F. Pech, an obscure collector residing in 

 Washington, D. C, prepared a list of plants collected by himself in various parts 

 of Missouri, chiefly during a temporary residence at Louisiana, Missouri, and 

 through several visits to Potosi, Washington County. Scarcely any one ever 

 saw this catalogue and it has remained almost unknown up to the present. 

 Tracy, ^ in his Catalogue of Missouri Plants in 1886, includes about 1725 species 

 in his list, and in the preface he says "The following Catalogue is, I believe, the 

 first publication of any list of the plants of the State, excepting a 'Partial Cata- 

 logue of the Plants of Illinois and Missouri,' published by Mr. Geyer about 1842 

 M^hich has long been out of print." This statement is completely at variance 

 with the Catalogue itself in which he cites many species of plants collected by 

 Pech, a thing he could not have done, unless he had seen the Pech catalogue, 

 either in the Englemann Library or in that of the Missouri Botanic Garden, and 

 he makes no mention of it in the preface. As the Pech catalogue contains about 

 950 species of the higher plants of Missouri, Prof. Tracy added to the flora of the 



1 Tracy, vS. M. Catalogue of the Phanerogams and Vascular Cryptogamous Plants of Mis- 

 souir. 1886.
