(See Fig. 7.) with 34 in Uiiiotlicra lamankiaiia. The brittleness character- istic of the tissues of nibrincivis may be seen to extend even to the hairs, since these structures are easily detachable from the dried specimens, and hence giving rise to the conclusion that lubrincn'is is less densely pubescent than lamankiaiia as given in the systematic description Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York Botanical Garden.
