FARWELL, DETROIT, MIOHKJAN Reprinted from the Second Annual Report of the MICHIGAN ACADEMY OF SCIENCE A CATALOGUE OP THE FLOE A OF DETROIT. O. A. FARWELL, DETROIT. (Reprinted, with additions, from Eleventh Annual Report (,'ommissioners of Parks and Boulevards, Detroit.) My field work at Detroit has been extended over a series of eight years and has been confined for tlie most part to the eastern part of the city. In Detroit, as in most western cities with a territory of several miles in extent, there are several localities where the soil' has not been turned b}' the ploughshare nor the forest disturbed by the woodman's ax. Such a place is that known as the Linden Park sub- division. It is a plat of land comprising several acres and lies east of the boulevard between Kercheval avenue on the south and Gratiot avenue on the north; at the. northeast corner of this plat is situated the old race course and driving park, now overgrown with shrubbery, etc. Belle Isle is an island at the head of Detroit river, about two miles long by one-half in width. The lower half has been largely cleared and improved for park purposes, but the upper half is still adorned with its virginal vegetable splendors. It is to Detroit what Coney Island, Central Park, etc., is to New York and is visited by thousands of pleasure seekers every day during the hot summer months. It is a }»art of the Detroit park system and in order to gather any of the wild plants that grow ui)on the island a permit from the Board of Park and Boulevard Commissioners is a si)ie qua noii : I have been most fortunate in this respect, having been able, with but one exception, to obtain a permit each year. The greater part of the plants mentioned in this list have been collected from one or the other of these localities, but the grass}' banks along the thinly populated streets, the ditches or gutters, and the ballast grounds have yielded some interesting things; also the wooded fields near Palmer Park (of the park system of Detroit) but this locality is outside of the city. The character of the soil is much the same in all these places, it being a low, slightly undulating plain mainly of clayey composition. We will not therefore find a varied flora. In the canals, rivers, and ponds may be seen the water lilies, the millfoils, the potamogetons and the utricu- larias; the low marshy grounds give rise to the buttercups, lilies and sedges; while such })lants as the St. John's Wort, compositiB and figworts are usually found growing on the drier grounds. In the River Rouge in the western part of the- city may be found the rare American lotus, Xchimho Icutva (Willd.) Pers. This, however, I have been given to understand is not indigenous to this river but has probably been intro- duced from near Monroe. In Gray's Synoptical Flora the plant is said to be indigenous from Michigan and Minnesota to Texas and eastward. It has been said, however, that throughout the central states the plant is only an introduction, brought north by the Indians from farther south. Pota)iio(/cton rutilus, Mr. Wheeler informs me, was collected by himself in Detroit river just above Belle Isle but I have not as yet 32 MICHIGAN ACADEMY OF SCIENCE. seen it, it is a rare species in Michigan, liaviiijj; been found, I belie\'e, in only one or two localities. The ferns are few in number and each s])ecies is itself scarce; in the woods on Belle Isle may be found the Urijopterls simulata, recently se[)arated from J>. Thcli/ptcri.s (Lin.) A. Gray by Mr. Davenport. It is a rare fern and more commonly met with in the eastern states. Michi- gan has not before been included in its range. Some eastern plants have been creeping west; among these may be mentioned the Cardainlne hirsuta Lin., th6 bitter cress; the Geum vcnunn (Raf.) T. & G. or spring avens; the Phjjsalis PhUadelphica Lam., one of the ground cherries; the Euphorbia hirsuta (Torr.) Wiegd., the hairy spurge; and a variety of chicory Chicorium Intijhus Lin. rar. divaricdta DC. The Cardaniine is rare in this country, being confined generally to the eastern Atlantic states, it is the first time, I believe, that it has been reported from west of the Aj^palachians. It was found in moist dense woods on the upper half of Belle Isle. The Euphorbia is another rare plant not before refwrted from west of New York; it has recently been separated from the E. nutans or E. hyperici- folia which aggregate has given rise to several so called species. Another, the Aster cricoides L. var. pJati/phi/Uus T. & G. has crept up from the south; it is the first time it has been recorded for Michigan, and is quite common near the water works, on grassy banks. There is another peculiar form of aster which, perhaps, may turn out to be the rare Aster amcthj/stinus Nutt. but it requires further study. A rare and interesting find, as ballast waifs, were the Pacific coasi Lupin us poll/carpus Greene, Trifolium furcatuin Lindl. and the T. dc- pHupvratuin Desv. Among other ballast plants may be mentioned the Belladonna {Atropu Belladonna Lin.); the Ajowan (Caruin Copticum (Lin.) Bth. & Hk.f.); and the common garden beet [Beta rulgaris Lin.) I'robably a number of plants found on Belle Isl^ have been introduced by means of bou(iuets taken to the island by pleasure seekers and picnickers; as such, perhaps may be mentioned the American cowslip, {f)odecathcon Meadia Lin.), the Hellebore [Hellehorus viridis Lin.), the Kattlebox (Crotalaria sae/ittalis Lin.), and the False Kue Anemone [Isopf/runi biternatuni (Raf.) T. iV: G.). Several of our old and well known ])lants considered as single species by our older botanists have been split up into several by the younger botanists of the present generation. Whether or not these segregations are well taken can be told only by future field work and careful study. Among the old species so treated may be mentioned Fanicum diehotoinuni. Lin. which has been split into innumerable species of which we have three, the P. Columbianum Scribn., P. pubescens Lam., and P. lanuginosa Ell. Agropi/ron repens (L.) Beauv. has been divided and we now have in addition to the type Ihe varieties agreste Anders, and pilosum Scribn. ^: Sin. and .1. l^niiUiii Rydb. Sisi/rincliiuin Bcrniudlana Lin. has also been segregated and we now have aS*. graniinoides Bicknell and S. albiduni Raf. On the northeast corner of Belle Isle is an artificial lake constructed to reclaim a large tract of marshy ground. On the present site of the lake was discovered, several years ago, a peculiar Sisi/rinrhiuni. Instead of having flat winged stems and leaves as usual these were almost thread-like or terete; Ihe bases of the leaves were FARWELL ON THE FLORA OF DETROIT. 33 somewhat broadened and slightly hastate hence the name S. hastilc. The construction of the lake mentioned above, I have no doubt, has destroyed the locality. Another species collected by the author near Birmingham has been named by Mr. Bicknell after the discoverer. I believe that several other new species from Michigan have been described as well as a score or more from other districts of the country. Tiola ohliqua Hill and Viola sororia Wild, have been eliminated from V. ciicidata Ait.; V. emarginata (Nutt.) Le Conte and V. ovata Kutt. have been separated from V. saglttata Ait. The common plantain ever- lasting {Antennaria plantaf/inifoUum (Lin.) Richards.) has been divided into a score or more species. Among those found at Detroit may be mentioned A. neodioica Greene rar. attenuata Fernald; A. neglecta Greene; A. occidentalis Greene; and A. arnoglossa Greene var. amhigens Greene. This list does not by any means represent a complete flora of Detroit, but only the results of such work as I have been enabled to do in the field. The sequence of families and nomenclature adopted in this list, except where the application of the rules of priority would require a change, are those exemplified in the Naturlichen Pflanzenfamilien of Engler and Prantl.
