266 "REMARKS ON BOOKNIA AND RYKIA, 



plant had thrown out a female blossom from its centre, which was then 

 18 inches long^ and so closely surrounded by leaves, that any one stand- 

 ing below could not see the flower. I immediately had this blossom, 

 which was not probably very long blown, drawn ; to wliicli I now invite 

 your attention. It was a female compound spadix, surrounded with 

 lancet-formed sheaths, edged with white, strong spines. Of those spa- 

 dices, which somewhat resembled unripe pine-apples, and wbich were 

 twelve in number, T examined one immediately, to ascertain the po- 

 sition of the ovule, and what was in connection with it. I remembered 

 to have seen this species in the conservatories of the garden at Pans, 

 where it is also called P. re/lexus, in which I have been supported by 

 Wendland (Index Palraamm, Cyclanthearum, Pandanearura, quse in 

 hortis Europse coluntur. Hanoveras, 1854). 



When at last, in 1853, the growth was complete, and no more change 

 in the colours took place, I had the whole blossom cut off, and sent to 

 my friend M. 0. M. E. Ver Huell, Vice-Admiral of the Dutch Navy, 

 who kindly forwarded the handsome drawing whicb I have had the 

 honour to present to you, and which I hope soon to publish in my 

 'Nova Genera Pandanearum.' 



I am come to the conclusion that this Fandanus must be the type of 

 a new genus, which must be principally grounded on the structure of 

 the fruit ; and I venture to propose this genus, although of course I have 

 not been able to obtain any ripe seeds. I call the genus Boornia, and 

 will endeavour to give briefly its diagnostics.
