XXIX. THE PEA AND ITS TRIBE. 



Description. — Of this large and important Order we

2'/ie Te?idrlls, A new feature now appears. Tendrils

 leaves, and they are themselves compound. Each tendi-il 

 consists of 3 or more coiling threads or fibers — aids to the 

 plant in climl)ing.t Leaves thus furnished are called cirrltoits. 



The I?iJlo7"esce7ice consists of peduncles springing from 

 the axils, each bearing 2 or more white flowers. 



* Habit denotes the form, appearance, and conduct of a plant, as It would strike 

 the general observer, without reference to scientific accuracy. 



t The action of a tendril looks almost like iiitelliLjcnre. It remains extended, and 

 straight, with only a slight curve or hook at the extremity, as if blindly searching for 

 some object to lean upon. If such fcupport is not soon fouud, it ofteu sweeps around
