CLASS V. ORDER III. 125 



The different species of Viburnum are fine flowering shrubs, 

 and with the Elder next described, constitute a principal orna- 

 ment of our woods and thickets during the first part of sunomer. 



137. SAMBUCUS. 



Sambucus Canadensis. L. ^ Common Elder. 



Cymes five parted ; leaves nearly bipinnate, stem 

 shrubby. Willd. 



Michaux says he could observe no difference between this spe- 

 cies and the Sambucus nigra of Europe, except in size, the latter 

 being a tree, the former a shrub. Leaves pinnate, the lower 

 leafets double or ternate, and all of them oblong-oval, sharply 

 serrate, tapering to a very long and acute point. Flowers white ; 

 berries blackish ; both considered medicinal. — June, July. 



Sambucus pubescens. 3Ix. Panicled Elder. 



Bark verrucose ; pairs of leafets two, oval-lanceo- 

 late, subpubescent underneath ; cymes panicled. 



A smaller shrub than the preceding. Leaves pinnate. Leafets 

 five, lanceolate, sharply serrate and acuminate. Flowers white, 

 in a panicle, with opposite, divaricated branches. Calyx teeth 

 acute, spreading. Segments of the corolla oval, revolute. Sta- 

 mens inserted on the corolla. Style very short, ending in three 

 brownish stigmas. 



Common in Vermont and the interior of New England, though 

 I have not seen it near the sea coast. It is hardly to be distin- 

 guished in the dried specimen, from S. racemosa of Europe. 



138. RHUS. 

 Rhus glabrum. L. Smooth Sumach. 



Glabrous: leaves pinnate, of many pairs, leafets 

 lance-oblong, serrate, whitish underneath, flowers 

 dioecious. 



A common species of Sumach found about fences and borders 

 of fields. Petioles and leaves unarmed and smooth. The flow- 

 ers are dioecious. Barren panicle much larger and spreading. 

 Petals twice as long as the calyx, subacute, green. Stamens
