NEW OR RARE PLANTS 



(Noticed since our last.) 



CALLICHROA PLATYGLOSSA. Golden Callichroa. (Bot. Mag. 



COMPOSITE. SYNGENESIA SUPERFLUA. 



1. This is an annual plant of moderate beauty, quite hardy, and nearly 

 allied to Doronicum. The flowers are yellow, with deeply cut foliage. 



EPACRIS IMPRESSA var. PARVIFLORA. Small flowered pitted Epacris. 



(Bot. Reg. 



EPACRIDACfcyE. PENTANDRIA MONOGYNIA. 



2. As the name implies, this is a variety of E. impressa, sent to this coun- 

 try by Mr. James Backhouse, who has been engaged for some years tra- 

 velling on a benevolent mission in New South Wales. It is now suspected 

 that the genus Epacris, especially the species Impressa, and others nearly 

 related to it, are merely varieties of each other. In speaking of E. im- 

 pressa, Mr. Gunn, a high authority on this genus, says, " the colours vary 

 from a deep red through all the paler shades of blush to purewhite, so that 

 colour coustitutes no distinction ; the size is also variable." He distin- 

 guishes four chief varieties, viz.— 1. Red flowering, tall ; 2. Red flowering 

 dwarf; 3 White flowering, tall; 4. White flowering, dwarf; in addition to 

 which, many others might be named. 



COOPERIA PEDUNCULATA. Pedunculated. (Bot. Mag. 3727. 



AMARYLLIDEJE. HEXANDRIA MONOGYNIA. 



3. A native of Texas; flowers, white with a tinge of green on the outside, 

 it blooms during the night, and has a peculiar primrose fragrance ; it 

 appears to require a stove temperature. 



CALADIUM PETIOLATUM. Long Stalked. (Bot. Mag. 3728. 



AROIDEA. MONJECIA MONANDRIA. 



4. Tubers of this singular looking plant were sent to this countrj by Mr. 

 Boaltbee, Junr., from Fernando P<> ; the plant has bloomed in the collection 

 of Joseph Boaltbee, Esqr., Springfield, near Birmingham. The tubers are 

 similar to the potatoe in appearance, but are poisonous. The spatha is of a 

 dark purple colour, and inside of it is a black purple ; the anthers are of a 

 pretty cream color. 



BLETIA PARKINSONIA. Mr. Parkinson's Bletia. (Bot. Mag. 3736. 



ORCHIDACE*. GYNANDRIA, MONANDRIA. 



5. Introduced from Mexico by H. M., consul general, Mr. Parkinson, after 

 whom it has been named. It is a very singular and distinct kind producing 

 flowers much narrower than any other, and of a pale rose colour with the 

 column and lip shaded yellow and purple. It is cultivated at Woburn Abbey, 

 where it blossomed for the first time in January last, the treatment applicable 

 to other species will also apply to this.
