PLANT NOTES, ETO., FOR 1926. 31
1645. T. HAMATIFRONS Dahlst. in Trans. Bot. Soc. Edin. 302, 1926.
In its spotted leaves it has a resemblance to the Spectabilia, but its fruits
remind us of Vulgaria to which group it probably belongs. In the form
of its leaves and their lobes it is very like hamatum, but differs especially
from it in its narrow recurved, not marginated, outer phyllaries. Clouster
