16 TRANSACTIONS AND PK0CP:ED1NGS OF THE [Sess. LXV. 



casucal occurrence of GUmcmtn at one locality in 

 Shetland. 



In England and Wales there are existing records of 

 Glaucium in no fewer than twenty-eight out of the thirty 

 maritime counties, the two exceptions, strange to say, being 

 Northumberland and Durham. 



In Ireland the recently-issued second edition of the 

 " Cybele Hibernica," by Messrs. Colgan and Scully, states 

 Glaucium to be found on the coasts of almost all Ireland ; 

 and that, though local, it is abundant in Dublin and 

 Wicklow, rare in many of the other maritime counties, 

 and absent from the two north-easterly ones — Antrim and 

 Londonderry. 



In north-western Europe, Mr. Arthur Bennett, F.L.S., 

 kindly informs us that Glaucium occurs at eleven coast 

 localities in south Norway, and in the provinces of Halland 

 and Bohus, in Sweden ; in Holland also, though it is rare, 

 and in Belgium, though very rare. 



The home of the six species of Glaucium known to 

 science is the Mediterranean region. Two only, G. flavum 

 and G. corniculatum, occur in France, and the same two in 

 Italy ; but all six are met with in Syria and Palestine, and 

 are described in Dr. Post's recently issued " Flora of Syria 

 and Palestine." One, G. alcppicum, Boissier, has petals of 

 a rich crimson colour, and all, excepting G. Jiaimm, are, 

 strange to say, inhabitants, not of the coast - line, 

 but of arid ground inland. G. arabicum, Fresenius, is 

 met with in stony places between Jerusalem and 

 Jericho ; and G. grandijiorum, Boissier, in the valley 

 of the Kedron. 



We wish only to refer, in conclusion, to a structural point 

 which strikingly distinguishes the plant with which this 

 paper has to do, viz. its enormous mature pod, which 

 attains to a length of ten, and sometimes even twelve, 

 inches, and which leads to the plant's receiving its English 

 name. This pod is a siliqua, formed of two carpels having 

 parietal placentation. Though structurally one-celled, the 

 ovary becomes two-chambered, owing to a cellular spongy 

 development of the placentas, known only to occur in the 

 genus Glaucium.
