Q. pseudosuher ^. aegj/lopifolia A. De Candolle, ProJr. xvi. pt. ii. 44 

 (1864). — Q. Cerris e. mhperennis /3. Lucombcana Dippel, Ilaiidb. Laubli. 

 II. 97 (189!^). — Q. fulhamensis Lucombcana Zabel in Beissner, Schelle & 



Zabel, Handb. 71 (1903). 



This variety forms a round-headed tree with the bark not corky; the 

 leaves are narrower and k)nger than in the typical form and liave about 7 

 pairs of trianguUir lar^e teetli; the subulate scales of the tur])inate cup are 

 partly reflcxed and partly erect.

Loudon, Arb. Brit. iii. 1856 figs. 1715, 1717c, 1718 (1838). — Q. Lucom- 

 beana var. crispa Henry in Elwcs & Henry, Trees Gt. Brit. v. 1261 (1910). 



This dilTers from the preceding variety chiefly in the very corky bark and 

 in the smaller leaves w^ith wrinkled margin. 



X Q. hispanica var. heterophylla, comb. nov. — Q. Cerris 14. ketero- 

 phylla Loudon, Arb. Brit. m. 1857, fig. 1719 (1838). — Q. Lucombeana var. 

 heterophylla Henry in Elwes & Henry, Trees Gt. Brit, v., 1261 (1838). 



Leaves oblong, irregularly and deejjly lobed, in the middle often with a 

 deep wide sinus on each side leaving only a narrow margin at the midrib.

Q. Ilex Var. divers if ol 



Hort. apud Nicholson, Hand-list Arb. Kew, ii. 189 (1896).— Q. Lucom- 

 beana var. diversijolia Henry hi Elwes & Henry, Trees Gt. Brit. v. 1262, t. 



339, fig. 71 (1910). 



The leaves are somewhat similar to those of the preceding form, but are 

 smaller; the cup of the fruit is hemispheric with shorter partly appressed 

 scales; the branches ascending, the bark corky.

Q. sessiliil 



laciniata Koehne, Dendr. 130 (1893), not Duchartre. — Spaeth in Mitt. 

 Deutsch. Dendr. Ges. xxii. 138, figs. 18-20 (1913). 



This is a peculiar form with deeply incisely lobed leaves, the narrow lobes 

 pointing forward. It had to receive a new name on account of the older 



Q. sessilifl

Q, sessilifiora longijol 



rissen & Zoon, Prijs-Cour. 49 [190.?], nomen. — Q, pedunculaia var. Ion- 

 gifolia Bean, Trees & Shrubs, ii. 321 (1914), not Kirchner. 



This very distinct and peculiar form diff'ers from the type in its elliptic 

 to oblong entire leaves obtuse at apex and auricled at base; the fruits are 

 borne on a very long and slender stalk. Nothing is known to me of its 

 origin; it was received at the Arnold Arboretum in 1903 from the nursery 

 of Jac. Jurrissen & Zoon of Naarden, Holland. The form had to receive 

 a new name on account of the older Q. pedunculaia 22. cucuUata longifolia
