64 AMERICAN MIDLAND NATUI^ALIST ( 



fallen off. I select as type No. 1043 1 of • my herbarium, found 

 myself Oct. 17, 1912, one mile north of Hudson Lake (Laporte 

 Co.), Ind., a short distance in a Tamarack- White Pine bog. The 

 swamp formerly contained an abundance of Pinus Sirobus Linn., 

 which has since disappeared almost completely by the woodman's 

 ax. Though the plant possesses a number of good characters 

 that led me at first glance in its native habitat to recognize it 

 as very different from the other Witch Hazels of our region, I 

 refrain from publishing it as a species not having studied it in 

 all its seasonal changes, nor having found any trace whatever of 

 fruit. 



Hamamelis virginiana var. orbiculata var. nov. 



Frutex cum ramis atro-cinereis glabris nisi in summitate et 

 ibi tomentulosis. Folia orbiculata, firma, vel subcoriacea, parva, 

 1.5-5 cm. longa, (saepe latiora quam longa, maxima nunquam 

 longiora quam 5 cm.) apice obtuso vel rotundato, basi cordata plus 

 minusve inaequali; margine dentato vel eroso-undulato vel crenato; 

 folia subtus dense tomentulosa ferrugineis pilis, vel glabra, in 

 superficie aliquando pubescentia, Petioli i cm. haud excedentes, 

 crassi, tomentulosi. 



This plant differs from the preceding in shape and texture of 

 the leaves very strikingly. The habit of the plant with its smooth 

 gray branches and short internodes and numerous flowers is 

 noticeable at first glance. The buds are pubescent and the outer 

 bracts short, giving them the appearance of a minute acorn. The 

 shape of the leaves is very constant and notable, the apex scarcely 

 •larger than a marginal tooth and often undefined. The teeth are 

 small. The plant called H. rotundifolia Raf. or H. macro phylla 

 of the south could not be mistaken for it owing to the larger leaves 

 of the southern plant, whether the latter be recognized ever as 

 either species or variety. The leaves of the southern plant are 

 described as 3-4 inches long. 



The type of H. virginiana var. orbiculata was found in the 

 dune region of Lake Michigan at Tamarack about 7 or 8 miles 

 west of Michigan City, Ind., on Sept. 22, igif"", and is No. 719 

 of my herbarium. The flowers were not as yet in bloom and the 

 plant perhaps deserves specific rank owing to its striking vegetative 

 characters alone.
