233. MAGNOLIA. 

 MAGNOLIA GLAUCA. L. Small Magnolia. 



Bigelow, Medical Botany, PI. xxvii. 



Leaves oval, glaucous underneath ; petals obovate, 

 narrowed at base. 



Tins I believe is the only species of its superb genus, which 

 has been found native in New-England. The bark of the young 

 twigs is of a bright-smooth green, with rings at the insertion and 

 scars of the leaves. Leaves scattered, petioled, regularly ellip- 

 tical, entire and glabrous. Their under side, except the midrib, 

 is of a beautifully pale, glaucous colour, by which the tree may 

 be distinguished at a distance. When young, this surface is 

 covered with a silken pubescence. Flowers solitary, terminal, 

 on a short, incrassated peduncle. Calyx of three spatulate, ob- 

 tuse, concave segments. Corolla of from eight to fourteen obo- 

 vate, obtuse, concave petals, contracted at their base. The 

 stamens are very numerous and inserted in common with the 

 petals on the sides of a conical receptacle. Filaments very 

 short; anthers linear, mucronated, two-celled, opening inwardly. 

 Germs oval, collected into a cone, each one divided by a furrow, 

 and tipt with a brownish, linear, recurved style. The fruit is a 

 cone, consisting of imbricated cells, which open longitudinally 

 from the escape of the seed. Seeds obovate, scarlet, connected 

 to the cone by a thread, which suspends them some time after 

 they have icillen out. It grows plentifully in a sheltered swamp 

 at Gloucester, twenty-five miles from Boston, which is perhaps 

 its northern boundary. Flowers in July. Bark aromatic and 

 bitter.

LlRIODENDRON TuLlPIFERA. Tulip TrC6. 



Bigelow, Medical Botany, PI. xxxi. 



Leaves lobed and truncated. 



One of the noblest trees, both in size and beauty, of the Ame- 

 rican forest. The branches of the Tulip tree are of a greyish 

 colour, inclining to red. The buds, which terminate them in 

 winter are obovate, and flattened or compressed into a sharp 

 edge at the extremity. These buds arc made up of a number
