^i gau 



That a juft judgment may be formed, upon what grounds we have taken up a fpecific diftin<Sion, 

 between the only two fpecies we poliefs of this genus; fo diflimilar in our opinion, but, which have 

 been conlidered 5s fcarcely to be deemed varieties, by much abler botanifts than ourfelves profefs to 

 be; we have given the figures of both in confcquence. Much is it to be regretted, that the whole na- 

 tural order of plants forming the Apocinea; of Jullieu, fo charaflered in themfelves, have not under- 

 gone a proper revifion, in claliification, upon the original Linn.tan sexual principles; which, we muft 

 fuppole, iiave been left in the prelent bewildered chaos, from the intricacy, fingularity and minute- 

 nefs of the parts, being fo difficult to develope. From critical and aftual obfervations, taken from 

 the living plants, we are in hopes of being able to illuftrate, and correct where necefiTary, the cha- 

 radters of fuch as may come under our review. 



Upon the changing the clafs of this genus, there needs no comment; as moft authors seem to 

 allow, though they have not followed the hint, that it is properly Gynandrous; although they have not 

 equally agreed as to the Order; fome taking the glands, furrounding the fummit, for the chives, and 

 fome, for the fummits themfelves, of a columnar Ihaft. Dr. Smith, who has figured our other fpecies, 

 has juflly taken, the parts fixed to the five glands, for what they certainly are; as may be eafily traced 

 through the whole order of Orchideoe, where the chives are nearly fimilarly placed and fo hooded. 



The Genus is by no means new, in name, having been fo titled by Linnaeus, from the names of 

 Pergulans and Pergulanus of Burman and Rumphius; who derived them from the ufe made of the 

 plants by the natives, of the weflern coafi of the peninfula of India; where, they are cultivated to 

 form arbors, for the agreeable flavour of their flowers. This fpecies was firft introduced about the 

 year 1784, by Sir Jofeph Banks, Bart, fome time before the other fpecies; wherefore, we have given 

 it the pretr rence. It is propagated by cuttings, and (hould be treated in the fame manner as direfted 

 for the Crata^va cappiroides of our lafl Number, to have it flower in perfe6tion. The figures of both 

 fpecies were taken, in Augull, from two plants in the colleftion of J. Vere, Elq. Kenlington Gore; 

 where, Mr. Anderfon (to whom we mull beg our fincere acknowledgments for his frequent and ready 

 obfervations and aflillance) informs us, they are treated in fuch manner.
