ellipsioid simple spores •008-012 millim. long, -OOiS-'OOSS millim. 

 thick, and paraphyses usually somewhat thickish, clavate. Com- 

 mon on maritime rocks on the coast of Kincardineshire, including 

 X. lainea^ Frs., and L, Jielicopts, f. dilittior, Njl. 3. Lecanora varia, 

 var. symmicta^ f. Uvescens, Nyl. Distinguished chiefly by its small 

 livid apothecia. Sparingly on trunks of old trees at High-beech, 

 Epping Forest. 4. Lecanora ventosa^ var. siihfestiva, Nyh, with 

 thallus greyish yellow, verrucose, granulate, thick, and apothecia 

 rusty red, margined. Eare, on a schistose boulder at base of Mor-

 to those of f. /estiva, Ach., of Lecanora ferruginea. 5. Lecidea 

 lapicida, * lithopMloides, Ny^-? with evanescent thallus, apothecia 

 white within; spores oblong, '011-015 millim. long, •0035-'0045

 dineshire coast and on Ben-nahoord, Braemar. 6. Lecidea ocel- 

 lata, * prcjeponensy Nyl., with thallus yellow, areolate or granulate- 

 verruculose ; apothecia subinnate, rugulose, immarginate ; spores 

 '015--017 millim. long, '008-*010 millim. thick. On stones of 

 the railway-wall between Nigg and Cove on the coast of Kincar-

Petalody * of the Sejpals in Serapias. 

 By J. T. MoGGHiT^E, Esq., F.L.S. 



(Plate III.) 

 [Read June 16, 1870.] 



It was in April, 1867, at Mentone, in the Departement des Alpes 

 Maritimes, that I first observed a plant of Serapias linguaj L., 

 presenting the abnormal development which I am about to de- 

 scribe. In this individual there were five expanded flowers, m 

 all of which the lateral sepals were modified so as to become 

 semilabelliform — that is to say, presenting all the characters ot 

 one half of the labellum along one side, and this the side ad- 

 jacent to the true labellum, while the opposite or posterior side 



* I borrow here the term uaed by Dr. Masters in his * Vegetable Teratology, 

 which conveys the assumption of the petal structure by the sepals, stamens, o 

 carpels. It will be remembered that the labellum is itself a modified petal.
