No. 443-] MUTATION IN PLANTS. 755 



In the first of these references Caspar Bauhin in Pinax on p. 

 245 (1671) writes of an American evening primrose under the 

 name of LysimacJiia Intea cortiicn/ata, as being a Virginian Lysi- 

 machia growing in the Garden at Padua in 16 19 and adds that 

 it was a pleasing plant and easy to propagate from seed. The 

 second reference goes back to Hermann's Catalogus, 1687, where 

 on p. 396 he records a species of Virginian Lysimacliia with 

 sulj^hur colored flowers as growing in the Garden at Ley den. 

 The third reference is to a plant with larger leaves and larger 

 flowers from the Altdorf Garden. In Jungermann's Catalogus 

 plantanivi quae in horto Medico Altdorpliino rcpcrinntur we read 

 that a Lysiviachia Intea Fl. inajoiibiis, adore Tabaci. and a (Lysi- 

 machia) Vitginiaiia Intea Delphininni qnonindnvi, were known in 

 the old Bavarian garden at Altdorf in 1635 and the statement is 

 again repeated in another Catalogns in 1640. It was a suffi- 

 ciently remarkable plant for Tournefort to note especially in his 

 Institutiones, and it might be inferred that this large flowered 

 plant from Altdorf was the ancestor of Ginothera lainarckiana. 

 It would appear as if a form of what is generally claimed to be 

 Qinothem biennis L. with delicate sulphureous flowers grew in 

 the Leyden Garden and another with larger flowers in the gar- 

 den at Altdorf. Under the same name, LysimacJiia corniculata, 

 an American evening primrose is said to have been growing in 

 the Messina Garden in 1640 and it was known in the Paris Gar- 

 den at about the same time or a little earlier and in 1653 in the 

 Copenhagen Garden. Morison also records it as occurring in 

 the Hortus Blesensis in 1669. This last reference is the one 

 quoted by Tournefort as his fourth species. Again under the 

 same name of L. coniicnlata Sherard speaks of it on p. 44 of his 

 Schola Botanica as growing in the Paris Garden in 1689 and, 

 presumably, descendents of the plants he saw were those col- 

 lected by Abbe Pourret a century or so after and later made the 

 type of the much discussed Qi. grandiflora Lem. = Qi. lamarck- 

 iana Sen. The plant described by Linnaeus in the Species 

 Plantarum was doubtless a composite species and it would be 

 particularly interesting in this connection to know just what he 

 meant by the plant described in the Hortns Cliffortianns as 

 being plentiful in the fields of Holland. A tracing of the speci-
