Though published and figured so long ago as 1855, Houl- 

 letia Landsbergi is a very little known plant, and has been 

 erroneously supposed to be a native of Brazil. The genus 

 to which it belongs is a small one, numbering only eight 

 published species, and is closely allied to Stanhopea, differ- 

 ing technically chiefly in the very narrow stalk of the 

 pollinia, but very much otherwise in form of flower. Two 

 other species are figured in this work, both with longer 

 more terete petioles and erect racemes, H. Brocldehurstiana, 

 Lindl. t. 4072, with the upper half of each sepal and petal 

 dark red, and a blue epichile ; and II. picta, Lindl. and 

 Eeich. f., t. 6305, with the corresponding parts of the sepals 

 and petals chestnut-brown, and the epichile yellow mottled 

 with almost black brown. The specimen of H. Landsbergi 

 here figured differs somewhat from the figure in the 

 Gartenflora, which has much paler sepals and petals, the 

 epichile of the lip is white with a yellow tip and a few 

 minute purple spots, the petals are much smaller, more 

 obovate-oblong, with a shallow notch in the inner margin, 

 which is not produced into a horn. 



H. Landsbergi was obtained by the Royal Gardens, Kew, 

 in the summer of 1891, from Mr. Richard Pfau, of the 



July 1st, 1894.
