STURTEVANT S NOTES ON EDIBLE PLANTS 323 



kinds, such as the curled, are frequently, and the sharp-leaved and oak-leaved are occa- 

 sionally grown as novelities. In these lettuces there can be offered only the synon^Tny of 

 a few of the varieties now known those which indicate the antiquity of our cultivated 



types. 



I. 



The Lanceolate-Leaved Type. 



Lactuca longifolia. Bauh. Phytopinat 200. 1596. 



Lattuga franzese. Dur. C. 244. 1617. cum ic. 



Lactuca folio oblongo acuta. Bauh. Pin. 125. 1623. Prod. 60. 1671. 



Lactuca Ion go at valde angusto folio. Bauh. J. 2:999. 1651; Chabr. 313. 1677. 



Deer Tongue. Greg. 1883. 



IL 

 The Cos Type. 



Pena and Lobel,' 1570, say that this form is but rarely grown in France and Germany, 

 although common in the gardens of Italy; and Heuze ^ says it was brought from Rome 

 to France by Rabelais in 1537. 



Lactuca intyhacea. Lombard Lettuce Ger. 240. 1597. 



Lactuca foliis endivae. Matth. Op. 399. 1598. 



Lactuca Romana longa dulcis. Bauh. J. 2:998. 1651. Chabr. 313. 1677. 



La Romaine Jard. Solit. 161 2 



Romaines. Vilm. 307. 1883. 



We can reasonably believe the lettuce of Camerarius to be very close to the Florence 

 Cos. The Lombard lettuce was grown as a sport in the garden of the New York Agri- 

 cultural Experiment Station in 1886, and the figures by Bauhin and Chabraeus may well 

 be the Paris Cos. It is not to be understood, however, that these figures represent the 

 improved forms of our present culture but the prototj'pes from which our plants have 

 appeared, as shown not only by resemblance of leaf -form but through the study of variables 

 in the garden. Ray, 1686, describes the Cos as having light green and dark green varieties, 

 and these, as well as the Spotted Cos, are indicated by Bauhin in 1623. 



III. 

 Headed Lettuce. 

 A . This is the sort commonly grown, and the figures given in the sixteenth century 

 indicate that the heading habit was even then firmly established. We have the 

 following synonyms to offer, premising that types are referred to: 

 Luctuca crispa. Matth. 264. 1554; Pin. 195. 1561. 

 Lattuga. Cast. Dur. 243. 1617. 

 La royalef Le Jard. Solit. 161 2. Quintyne 1690. 

 Laitue Blonde de Berlin syn. Laitue royale. 295. 1884. 

 Berlin 

 B. Lactuca sativa sessilis sive capitata. hob. Icon. 1:242. 1591. 

 Lactuca capitata. Dod. 645. 1616. 

 Very Early Dwarf Green. 



' Pena and Lobel Advers. 90. 1570. 

 'Heuze. G. Pis. Aliment i, v. 1873.
