CONTRIBUTIONS TO THE BOTANY OF MICHIGAN. 205 



C. interior Bailey is another form common in wet soil tliroughout the 

 State. C. canescens var. disjuncta Fernald and tlie var. siibloliacea 

 Lwstad are frequent in Keweenaw county. C. Muskingumensis ScJidv. is 

 common in moist woods near Ypsilanti and on Belle Isle. C. Crawfordii 

 Fernald and its variety vigens Fernald, are frequent in Keweenaw county. 

 C. tribuloides Wahl. var. turbata Bailey is a rare form of the species with 

 club-shaped spikes on the banks of the Montreal R. in Keweenaw county. 



Jiuicacece. 



The plant that has long passed as Juncus effusus L. is the form which 

 that author made his var. B. in the Sp. PI. of 1853; the type of the Lin- 

 nean species is the plant that is better known as J. arcticus Willd.; the 

 var. B. (J. effusus Am. Authors) should be known as J. communis C. A. 

 Meyer. 



J. communis C. A. Meyer var. pseudoconglomeratus {J. effusus var. 

 cougolomeratus Englm. mostly not J. conglomeratus Lin.). This is the 

 form with a sessile, compact, globular inflorescence and constituted the 

 greater part of Engelman's var. conglomeratus. 



J. bufonius L. var. hybridus (Brot.). This is the dwarf form with 

 the flowers crowded at the ends of the branches and is Engelman's 

 var. fasciculatus. 



J. tenuis Willd. has been split up into several species and varieties by 

 Mr. Wiegand. We have the J. tenuis Willd. J. Dudleyi Wieg.. J. interior 

 Wieg., and J. occidentalis (Coville) Wicg. The first two I have collected 

 at Detroit and in Keweenaw county ; they are probably common through- 

 out. The third is not common around Detroit in vicinity of Palmer Park, 

 and the last is rare in Keweenaw county. J. Canadensis J. Gay. var. 

 hnichjcephalusEngelm. is common at Orion, and the variety brevicauda- 

 tus Engelm. is common in Keweenaw county. 



Liliacece. 



The Tulipa Gesneriana Lin., the common tulip, has escaped near Ypsi- 

 lanti; it probably should be classed as adventive. Ornithogalum nutans 

 Lin., the so called Star-of-Bethlehem, has escaped near Ypsilanti. Muscari 

 botryoides (L.) Mill., the grape hyacinth, is frequent in woods and along 

 fences near Y'^psilanti. 



Amaryllidacew. 



Narcissus Poeticus Lin., is an escape near l^psilanti. 



Orchidacece. 



Recent revisions of Orchidaceous genera show that the Keweenaw 

 plant I referred to Peramium repens (L.) Salish. is not the type as sup- 

 posed but the var. ophioides {Fernald) Heller.; and that the P. pubescens 

 (Willd.) MacM. includes also the P. tesselatum (Lodd) Heller. The 

 latter is the more common and I have collected it at Ypsilanti and 

 near Orion.
