me specimens in the Banksian Herbarium, collected by David Nelson in Otahaite, in Cook's third voyage, dlfforino- 

 in no respect from my fern. The same gentleman has also had the goodness to procure the drawing, from which 

 .the accompanying plate was engraved, in which fig. 2. represents a leaflet of the Otahaitean fern. Tlie lines of fruc- 

 tification before the bursting* of the indusium are perfectly cylindrical, and look like a number of microscopical sausages, 

 attached to the underside of the fern ; and it is this singular appearance, which is so happily indicated in the name 

 of the genus.

This and the following most lovely plant are natives of the lofty range of mountains which confine Bengal towards 

 the district of Sillet in an easterly and northerly direction. They were introduced into the Hon. East India 

 Company's garden at Calcutta in 1816, and I have often had the satisfaction of seeing tiiem in flower there. Our 

 mode of treating these and similar Epiphytes, is to place them on beds made of brickwork, raised four or five feet 

 from the ground, containing a rich mould mixed with a large proportion of pebbles and resting on a stratum of large 

 stones or masses of vitrified bricks, so as to admit of being perfectly drained. The surface is covered with a quantity 

 of moss, and the whole structure is placed in a shady and sheltered situation, corresponding to the natural place of 

 growth of such plants. By the aid of these beds, and by a constant attention to the necessity of keeping the roots as 

 well as the plants themselves moderately moist. I have succeeded in cases even where there was but little hope ; 

 for instance, with plants from the higher region of Nipal, and even from Gossain Than in the Himalaya. 



Our species (though quite distinct) approaches to Epidendrim pnseo.v of the late Sir. J. E. Smith, a botanist whose 

 name will be held in veneration as long as the Science has a single votary ; and whose loss is the more deeply lamented 

 by me, because on my return to Europe I had looked forward with great delight to the happiness of becoming per- 

 sonally acquainted with that truly excellent and amiable man.
