216 WYCH ELM. NORWAY MAPLK 



Ulmiis montana, Sm. Wych Elm (Fig. 108). A large 

 tree up to 80 — 100 feet in height, with more spreading 

 habit and thicker twigs and buds than U. carnjiestris, often 

 pendent at the tips. The leaves are larger and rougher, 

 the twigs darker coloured and deeper olive-brown, and 

 more stiffly hairy ; but the essential difference lies in the 

 fruit, which in U. campestris is deeply cut at the top and 

 the seed lies above the centre of the obovate fruit, whereas 

 in U. montana the fruit is broader and more nearly or- 

 bicular, with a shallow incision, and the seed lies nearly 

 in the centre. 



A A Bark loith very shallow fis- 

 sures. Floioers late, yelloicish- 

 green, the peduncle adherent 

 to a long hract. Fruits stib- 

 glohose. 



Tilia europcea, L. Lime (Fig. 98). For further 

 description see p. 204. 



4- -T- Spray with btids, twigs, leaf-scars 

 and leaves opposite decussate, and 

 tending to fork dichotomously 

 owing to the frequent conversion 

 of the terminal shoot to floicers. 



Acer platanoides, \j. Norway Maple (Fig. 109). A tree 

 up to 100 feet in height or more, but rarely seen so tall, 

 with an ovoid-conic to broadly pyramidal or dome-shaped 

 spreading crown. The deep grey bark is finely and closely 

 fissured with shallow longitudinal, but short, furrows, 

 and shows no tendency to scale off. The spray tends to 

 turn up at the edges, and bears rather large olive- or 

 reddish-green buds at the divaricating tips. 



The other two species of Maple have been dealt with 

 on pp. 180 and 185, and A. Pseudo-Platanus has a similar 

 habit to A. platanoides. The distinctions between the
