CCXL. Orcli'idecE. Collecting and Importing Orcliideous Epiphytes. — 

 " It is very much to be regretted that some more efficient means are not 

 taken to procure the plants of this description which abound in all the 

 tropical parts of the East. They are very tenacious of life, and require no 

 care in collecting, it being only necessary to strip them off the trees on 

 which they grow, and to suspend them in the cabin, never watering them, 

 but moistening them occasionally with a wet sponge. Captains of ships 

 might succeed in importing them without difhculty. The only caution 

 which requires to be taken is, that they should not be overwatered ; if this 

 is done, they are sure to die : it would be much better to give them no 

 water whatever. They should also, if possible, be collected in the dry 

 season, at which period they are naturally in a state of torpor." Professor 

 Lindley, in the Botanical Register for September, t. 1522., under Angrce'cum 

 eburneum. 



The Woodloiise is exceedingly destructive to all Stove Orchidcoiis Plants. — 

 Messrs. Loddiges state to this effect in their description of Maxillaria 

 Barringt6n?'cr, in their Bot. Cab. for July, t. 1824. Modes of destroying 

 this insect are prescribed in our Vol. VII. p. 280. and 486.

Banksii R. Br. Banks's ;4 lAJ cu IJ d Y.W New Zeal. 1826. D p.l Bot. mag. 3172 



Found on the banks of a stream which is received into the Bay of 

 Islands, in New Zealand, by Mr. Allan Cunningham, in 1826, who soon 

 after sent off plants to Kew. Mr. Bauer has found that its grains of pollen, 

 magnified by Ploessel's grand microscope 570 times lineally,or 324,900 times 

 superficially, exhibit a total deviation from those of all the hundreds of 

 specimens of orchideous plants he had before investigated. The species has 

 large leaves, and Mr. Cunningham had named the species P. macrophylla: 

 but Mr. Brown has identified it with a specimen found by Sir Joseph 

 Banks in New Zealand, when he accompanied Captain Cook round the 

 world, and of which a specimen or drawing still exists in the Banksian 

 museum. {Bot. Mag., Aug.)

" It is a neat little plant, requiring the same kind of treatment as ixias 

 and other Cape bulbs : that is to sa}', to be kept quite dry and quiescent 

 during summer. Under such management, Mr. Henderson, at Lord Mil- 

 ton's, succeeds in making it flower li-eely every spring." (^Bot, Reg., Sept.) 



Orchidea; § Vandeee. 



2537 MAXILLA'RIA. 



placanthfera Houk. flat-anthered ^ [Z3 cu | ... G.Y.Pk Brazil 1831 ? D p.r.w Bot. mag. 3173 



A newly introduced and well marked species, from the rich collection of 

 Mrs. Arnold Harrison, who received it from her brother in Brazil ; and 

 cultivates it, and the Orchideae generally, very successfully. {Bot. Mag.^ 

 Aug.) The time of its introduction to, and period of its blooming in, 

 England, are not stated : definiteness in these little matters seems unwel- 

 come to the editors of the botanical periodicals. 



gracilis S.C. slender ^ ES pr | au R.Y Brazil ... D p.r.w Bot. cab. 1837 



This curious little plant is very slender in habit, and must be constantly 



kept in the stove. It may sometimes be separated for increase, and should 



be potted in moss, vegetable earth, and small pieces of broken pots. {Bot. 



Cab., Aug.)
