 In Miocene formations at Kumi in Negropont. 



Leaf f in. long by J in. wide ; petiole ^ in. long. Not unlike a short leaf of E. glabra 

 L., but placed in this genus on insufficient evidence. 



II. KEY TO THE FOSSIL SPECIES OF EUCLEA. 

 Leaves petiolate, 



Leaf 3 in. long, acuminate at both ends, 1. E. miocenica. 



Leaf 4 in. long, narrowed at both ends, not acuminate. 2. E. Apollinis. 



Leaf sessile. 3. E, relicta. 



1. EUCLEA MIOCENICA, Ung. Syll. PI. Foss. in. p. 25. t. vni. fig. 8, 8* (1866). 



E. foliis lanceolatis utrinque acuminatis petiolatis integerrimis coriaceis, nervo primario 

 valido, nervis secundariis flexuosis ramosis rete nervorum tertiariorum laxo inter se conjunctis. 



Heer Mioc. Bait. FL p. 84. t. XXYIII. fig. 38 (1869) ; Schimp. Pal. Veg. n. p. 956. 

 n. 1 (1872). 



In marly schist, Croatia, Unger ; Rixhoft, Samland, W. Prussia. 



Leaf Sin. long by fin. wide; petiole ^in. long. Genus and family quite uncertain. 



2. EUCLEA APOLLINIS, Ung. Syll. PL Foss. in. p. 26. t. vm. fig. 10, 10* (1866). 



E. foliis lanceolatis breviter petiolatis integerrimis coriaceis, nervo primario valido, nervis 

 secundariis crebris flexuosis ramosisque rete nervorum tertiariorum laxo inter se conjunctis. 



Rhododendron Apollinis, Ettingsh. ex Ung. I.e. 

 In marly schist, Eocene ; Radoboj, Croatia, Unger. 



Leaf 4 in. long by fin. wide; petiole scarcely Jin. long, narrowed at both ends. Leaf 

 very like E. miocenica Ung. but rather larger. Prof. Schimper unites this with E. miocenica. 



3. EUCLEA RELICTA, Ung. Foss. Fl. Eub. in Denkschr. Kais. Wissensch. Math.-Naturw. 



VoL xxvii. p. 68. t. XL f. 39 (1867). 



E. foliis lanceolatis utrinque attenuatis sessilibus integerrimis coriaceis, nervo primario 

 valido, nervis secundariis angulo subrecto exorientibus flexuosis ramosissimis in retem nervorum 

 tertiariorum laxum divisis.
