ROSA PALUSTRIS
Swamp Rose
Native of eastern North America
Rosa palustris Marsh. Arbust. 135. 1785.
The swamp rose is the most common of the wild roses of eastern North America. Its range of distribution extends from Nova Scotia to Florida, Mississippi, and Minnesota. It grows usually in wet places, in open woods and copses. It is a handsome plant but does not have the large flowers and fruit of the glossy rose, Rosa virginiana, or the delicate foliage of the pasture rose, Rosa Carolina.
Two or three decades ago this rose was usually known under the name Rosa Carolina L., but the latter name was originally given by Linnaeus in the first edition of "Species plantarum" to a rose described and figured by Dillenius in his "Hortus elthamensis." Both the description and the illustration show that Dillenius' rose was our pasture rose or the same as Rosa humilis Marsh. Later Linnaeus received specimens of the swamp rose from America. Thinking that it was the same as his Rosa Carolina, he modified his description in the second edition, so that it applied better to the swamp rose than to the original R. Carolina. Most botanists have perpetuated this error. The great Belgian rhodologist, Crépin, pointed out the discrepancy as early as 1876, but was reluctant to correct the naming of the North American roses, being afraid of causing more confusion. It is only lately that American botanists have dared to apply the proper name, Rosa palustris Marsh., to the swamp rose. This is very appropriate, as the scientific name and the common one have the same meaning.
It is a well-known fact that many hybrids have been produced artificially among the roses, but not many persons know that natural hybrids are also found among the wild species. This fact is better recognized in Europe than in America. On account of these hybrid forms, the study of the roses, both wild and cultivated, is very difficult and the lines between the species are very hard to draw. Native hybrids of Rosa palustris with Rosa blanda Ait., R. Carolina L., R. johannensis Fern., R. nitida Willd., R. serrulata Raf., and R. virginiana Mill, have been recorded.
The swamp rose is a shrub one to six feet high, with often reddish stems, armed with short recurved prickles, which are flattened and one sixth to one fourth of an inch long. The leaves are rather dull, glabrous above, finely short-hairy beneath, with seven, rarely nine, oblanceolate or oblong leaflets, which are one to three inches long, finely and closely toothed; the stipules (lobes on the leaf-stalks) are narrow, for a long distance united with the stalk, often glandular-toothed on the margins. The flowers are usually several in a cluster which is often flat-topped; the flower-stalks usually have stiff gland-tipped hairs or bristles. The sepals are lanceolate with long tail-like tips, glandular-hairy on the back, tomentose within. The petals are rose-red, reversed heart-shaped, three fifths to four fifths of an inch long. The fruit is globose or nearly so, a little less than half an inch broad, and usually a little broader than high, bright red when mature, and more or less covered by gland-tipped bristles.
