Xt COMPENDltJst. 



Following pages contain besides descriptions keys to the determination 

 of the families, tribes, genera and species. 



If one supposes to have found in the keys the name sought after, he 

 should not omit reading the diagnosis itsflf, seeing the plants are determined 

 by more characteristics than those few admitted in the keys These are 

 mere expedients, no infallible guides; they chiefly had to be extracted 

 from the av.iilable diagnoses since I did not set eyes on a great part of the 

 plants. Furthermore it would have been like looking for a needle in a hay- 

 stack to insert all deviations from the normal forms. Consequently the use 

 of the keys may be sometimes the cause of going wrong. 



In comparing the collected plants with the descriptions given in this and 

 other works one should bear in mind that difl'erent authors are not always 

 unanimous in using botanical terms. So, for instance, the word ovale is not 

 rarely used for oval or even deltoid or another term, spreading for horizontal, 

 erecto-patenl for more or less oblique, conspicuous and inconspicuous for distinct 

 and indistinct, casta for rachis, costula for main vein, vein for veinlel, pinna for 

 Icbe or lacinia, medial for medial on the veins or medial between Ihccostae 

 [costulae) and edge, excurrent for directed towards the margin, forking for 

 fork branch, undulate (wavy) for sinualed with rounded lobes and sinuses, joining 

 (joined) for connected, united or confluent, curved sometimes for flexuose, &c.
