Broadleaved Plants with Opposite Compound Leaves

Tree Leaf Drawing Compound

Leafstalk not woody Leaves opposite

Leaf scars and buds opposite {useful in winter;

/ Leaflet

Only a few plants bear leaves of this type. Their identification, therefore, is comparatively simple when foliage is present. In winter, however, unless dead or evergreen leaves are attached to the twigs, there are no certain clues to indicate whether the plant once bore compound or simple leaves. Then, this Section must be grouped with the next, whose twigs also bear opposite (occasionally whorled) leaf scars and buds, I he twigs of a leafless unknown plant with opposite leaf scars may he compared with the drawings in Sections II and III.

Some alternate-leaved plants bear stubby, scarred, leaf-crowded spur branches. Care should be taken that their leaves and leaf scars are not assumed to be opposite or whorled because of this crowding. None ol the plants in our area with true opposite or whorled leaf scars ever develop spur branches. Twigs with un-crowded leaves or leaf scars should be selected for identification.

Acne is a name that is famous in its own right, but for all of the wrong reasons. Most teenagers know, and dread, the very word, as it so prevalently wrecks havoc on their faces throughout their adolescent years.
