Odontoglossum Insleayi 



Odontoglossum Insleayi makes n 

 nice companion to tlie ever popu- 

 lar 0. grande or "Baby Orchid." 

 It requires similar treatment to 0. 

 grande and flowers at about the 

 same time. While the flowers are 

 not as large as those of 0. grande, 

 they are nevertheless very attrac- 

 tive. The sepals and petals are 

 greenish yellow barred and blotched 

 with chestnut brown : the lip is 

 bright golden yellow, bordered with 

 cinnamon red spots. In habit of 

 growth it very much resembles 0. 

 grande. 



Here the jilants are grown in a 

 cool house where azaleas and other 

 plants requiring similar conditions 

 to grow in are kept all the year 

 around. In this house the temper- 

 ature ranges in winter from 45 

 degrees to 50 degrees at night, with 

 a rise of 5 degrees to 10 degrees 

 during the day, according to the 

 amount of sunshine available. 

 From the time the flowers have de- 

 veloped until the plants start to 

 grow again in spring very little 

 water is given, but during their 

 growing season they are freely 

 watered and if time permits they 

 are dipped in weak liquid manure about once or twice a 

 week. These plants, like most all of the Mexican 

 orchids, like plenty of sunshine all the year aiound; 

 ground glass gives all the necessary shade here. 



Osmunda fibre is used 

 compost.

IVY-LKAVED PELARGONIUMS 



An improved race of P. peltatum has come into com- 

 merce which is likely to supersede the scandent varie- 

 ties. The habit of growth of these newcomers is com- 

 pact, the trusses of flowers larger, and consisting of r. 

 greater number of "pips," and the colors more varied. 

 The older varieties are admirable subjects for clothing 

 a wall, suspending from a glasshouse rafter or principal, 

 attaching to a supporting pillar, or as a filling for bas- 

 kets, windows or balcony boxes; but as portable subjects 

 for the conservatory, or apartments, they are not exactly 

 fitted. Of varieties of this new race I may mention 

 Mrs. Hawley, a rosy crimson, semi-double flower, pro- 

 duced to the number of 6 to 8 in a truss supported on 

 moderately long stout petiole ; Sabrina, a single-flow- 

 ered, scarlet variety ; Eesplendent, with double flowers of 

 a rosy crimson tint, the truss of a large size ; Colonel 

 Baden Powell, of a lilac color, dotted with crimson — a 

 beautiful flower. Others of fine quality are Hector Gia- 

 cornelli, Mrs. W. H. Martin, semi-double and Southgate 



Perfection. The leaves of tlie?e varieties are of remark- 

 able substance, and of a vivid green color. 



NYMPHAEA MOOEEANA 



A species of Xymphaea under this name was shown at 

 the recent meeting of the Pioyal Horticultural Society 

 by J. Hudson, gardener to Leopold de Rothschild. It 

 seemed to be an improvement upon X. Marliaeea chro- 

 matella, a straw colored variety, having bright orange 

 stamens, fragrant, and a continuous bloomer during the 

 waimer months. jSTymphaea-Mooreana has deep yellow 

 flowers, and is equal to N. chromatella in floriferous- 

 ness ; the leaves are of great substance, without any mot- 

 tling; the blo.=soms when open are more globular, and 

 the petals of greater width. The plant is an acquisi- 

 tion to the race of hardy water lilies, and was sent to 

 Mr. Hudson by a correspondent residing in Australia 

 some few years ago. We thus have a native of subtrop- 

 ical Austrplia nroving itfclf capable of succ-eeding as 

 an ordiniirv inmate of a garden lake in southern Eng- 

 land, with its somewhat scvcic winter climate.
