C. PHAENOPYRUM (L. f.) Medic. Gesch. der Bot. 83 (1793). Mespi- 
lus Phaenopyrum L. f. Suppl. 254 (1781). Crataegus cordata Ait. 
Hort. Kew. ed. I, 2: 168 (1789); not M. cordata Mill. Dict. ed. VIII, 
no. 4 (1769) and in Fig. of Plants, 119, t. 179 (1760). This fine spe- 
cles was one of the first American thorns raised in Great Britain, 
being listed and illustrated by a fine colored plate (t. 13, f. 1) in the 
Catalogus plantarum...quae in hortis non procul a Londino pro- 
pagantur (1730). Philip Miller, who was one of the gardeners who 
prepared this catalogue and was doubtless familiar with this species, 
tells us in regard to his Mespilus cordata of later date, that it was 
raised in the Chelsea Garden (where he was gardener) in 1738 from 
seeds which came from America. Furthermore neither his descrip- 
tion nor his excellent colored plate of this later species corresponds to 
C. Phaenopyrum, but rather to some form of the Tenuifoliae, appar- 
ently nearest to C. macrosperma Ashe.
