Note on Tiarella cordifolia. 
Yiarella cordifolia has more than once been sent to’ us with 
somewhat attenuated and dentate or even laciniate petals, lead- _ 
ing one to suspect a possible crossing with JJitella diphylla. 
This is to ask those who meet with this anomaly to notice, where _ 
they meet with it, whether it occurs in more than single plants, 
and whether accompanied by the two plants.
