three places near Florence : Le Rose, a farm on the road to Sienna ; Galluzzo, four miles from 

 Florence ; and in the Val d'Arno, not far from the city on the south side. The form of the 

 flower, its robustness, and its smoothness, appear sufficient evidence of its identity with the self 

 tulips, from which the gay varieties of the tulip-fancier are bred. Bot. Reg. 



Thysanotus tenuis. Lindl. Slender Thysanotus. Bot. Reg. N. S. t. 50. A new species 

 bearing purplish flowers, obtained from the Swan River, by R. Mangles, Esq., in whose collection 

 at Sunning Hill it flowered in May 1837. This genus approaches near to Trichopetalum, 

 which differs in little beyond its polyspermous seed-vessel. It may be propagated by seeds.

ORCHID ACEiE. Lindl. § VANDEjE. Lindl. 

 Oncidium raniferum. Lindl. Frog-bearing Oncidium. Bot. Reg. N. S. t. 48. This is a 

 very small species of this extensive genus, and hangs down from the branches of trees instead of 

 growing erect. 



It is a native of Brazil and the Organ Mountains, and M. _Descourtilzmetwith.it in the damp 

 forests near Bananal ; this traveller observes, that it fixes itself to branches not exceeding twelve 

 feet in distance from the earth. This species must be cultivated in a very damp stove, where it 

 may be either tied to a piece of wood suspended from the roof, or grown in a pot. Bot. Reg. 



§ EPIDENDHEjE. 



Nemaconia graminifolia. Sepala conniventia lateralia cum basi prpducta. columns? accreta. 

 Petala subconformia minora cum sepalo supremo columnar coadnata. Labellum ascendens 

 revolutum apice bifidum cum basi producta columnae articulatum. Columna semiteres arcuata. 

 Clinandrium subrotundum apice appendiculatum. Gynizus sublunatus. Anthera 4-locularis. 

 Pollinia 4, angulata compressa. Caudiculis duobus pulvereis. Herba Mexicana. 



Caulescent. Stem about a foot high, covered all over with dry papillose sheaths, destitute of 

 leaves, and out of which shoot leafy branches about three inches long. Leaves alternate, linear, 

 three-ribbed, sheathed at the base ; sheaths covered with papillose excrescences, similar to those 

 on the stem. Flowers in pairs, arising from the apex of the branches, sheathed at the base with 

 sheaths similar to those on the leaves. Sepals ovate, acute, streaked with purple. Petals 

 smaller than the sepals, obtuse, streaked like the sepals. Labellum bifid at the apex, revolute, 

 marked like the sepals and petals. Column bowed, half-round. Gynizus somewhat crescent- 

 shaped. Anther four-celled. Pollen-masses four,, angular, compressed. Caudiculaj two, 

 covered with a powdery substance ; clinandrium apiculate at the apex. 



This is a very singular plant, for while in the structure of the sepals, petals, and labellum, it 

 very nearly approaches the genus Maxillaria, it has the pollinia and caudiculse of the tribe 

 Epidendreae. The stems have a very remarkable appearance in not having a solitary leaf, but 

 covered with husky papillose sheaths. The plant is not showy, but from its appearance seems 

 to be a free flowerer. 



It is a native of Kalappa, and was imported by George Barker, Esq., in the year 1837, in 

 whose collection it is.
