88 DIALYPETALOUS EXOGENS

Sepals 5, connected at base, deciduous. Petals 5. Stamens numer- 

 ous, the filaments more or less cohering in 5 parcels, sometimes

 spatulate petaloid scale (staminodium), opposite the real petals. 

 Ovary 5-celled; style single. Fruit a coriaceous or woody globose 

 nut, 1 -celled, 1- or 2-seeded. Trees; flowers in pendulous cymes, 

 with the lower half of the common peduncle adnate to the lower half

1. T. EUROPAEA, L. Leaves orbicular-cordate, acuminate; flowers 

 without petaloid scales. 



EUROPEAN TILIA. Linden, or Lime tree. 



Stem 30 to 50 feet high, the numerous branches forming a handsome symmet- 

 rical top. Leaves 3 to 5 inches long; petioles 1 to 2 inches long, flowers yellow- 

 ish-white. Peduncles 3 to 5 inches in length. 

 Hob. Streets, &c. Nat. of Europe. Fl. Beginning of June. Fr. Sept.

 but the leaves, soon after midsummer, assume a scorched appear- 

 ance.

 base, abruptly acuminate, subcoriaceous ; flowers with petaloid

T. glabra, Vent. $ Fl. Cestr. ed. 2. p. 312.

 the Sugar Maple, or Horse Chestnut, as ornamental shade trees.
