2 GENERAL REMARKS 



Whilst the PapiHonace£e adapt themselves to every climate 

 and are found distributed from the Equator to the Poles, the 

 Mimose^e and C^esalpineaj, on the other hand, prefer tropical 

 climates, where they are encountered in large numbers. 



The Papilionaceffi are plants which are well known and 

 easily identifiable by their inflorescence. The calyx has five 

 sepals, the corolla is composed of five petals : that which is 

 superior and completely external is called the standard ; those 

 which are lateral, their upper margins overlapped and lower 

 margins overlapping, are the wings: those which are in- 

 ferior, with their lower margins generall}' mutually adherent, 

 constitute the keel. 



The PapilionacecC are divided into eleven tribes : — 



I. Podalyrieae 



II. Genisteae 



III. TrifolieK 



IV. Loteffi ... 

 V. Galegege 



VI. Hedysareae 



VII. Viciese ... 



VIII. Phaseolese 



IX. Dalbergiess 



X. Sophorese 



XI. Swartzieae

The Cassalpinese possess flowers which closely resemble 

 those of the Papilionace^, only differing from them in the 

 aestivation of their corolla, which is imbricate in such a 

 manner that the posterior petal is enveloped instead of 

 enveloping. It is in this group that the flowers are most 

 irregular, for one meets with all sorts of anomalies, atrophy 

 of stamens, petals, &c. Such is the case in the locust tree, 

 which has no corolla. 



The Caesalpincce are divided into six tribes : — 



I. Sclerolobiese 



II. Eucaesalpiniere 



III. Ca'-siece... 



IV. BauhinicEe 

 V. Amherstieae 



VI. Cynometrcce 



Melanoxylon. 



Cse«alpinia, Haematoxylon. 



Cassia. 



Bauhinia. 



Tamarindus. 



Copaifera.
