HENDERSON'S HANDBOOK OF PLANTS. 



PAR 



above 50 degrees at night. To be sure, 

 there are quite a number of plants grown 

 in private rooms, that require a much 

 higher temperature; but to have satisfac- 

 tory results, the two divisions should be 

 kept in separate rooms, at the differ- 

 ent temperatures, say 50 degrees at i 

 night for the so-called green-house 

 plants, and 65 degrees at night for the 

 tropical or hot-house. A few of the 

 best green-house plants suited for par- 

 lor culture, the average temperature at ; 

 night being 50 degrees, are as follows: 

 Azalias, Abutilons, Ageratums, Callas, j 

 Cinerarias, Carnations, Cyclamen, Camel- i 

 lias, Echeverias, Ferns, (green-house,) 

 Ferns, (climbing,) Feverfews, Fuchsias, 

 Geraniums, (Pelargoniums,) Hoy as, (Wax 

 Plant,) Holland Bulbs of all kinds, Ivies, j 

 (Parlor and Hardy,) Lobelias, Passifloras, ! 

 Roses, etc. A limited list of the best 

 suited tropical or hot-house plants for I 

 parlor culture, the temperature at night j 

 to average 65 degrees, is as follows: Alia- j 

 mandas, Begonias, Bouvardias, Ca^,di- j 

 urns, Cissus, Crotons, Coleus, Dracaenas, j 

 Ferns, (tropical,) Heliotropes, Hibiscus, i 

 Poinsettia, Torenias, Tropaaolums, Palms, 

 etc. The instructions for Propagating, I 

 Watering, Potting, Killing of Insects, ! 

 Soil, Mulching, and all other operations i 

 given for culture of plants, will be found ; 

 under these different heads, and will be , 

 found equally applicable to the culture of 

 plants in rooms as in green-house or hot- 

 house culture. Saucers in which to place 

 the pots are sometimes a necessity in 

 rooms to save the floors from getting wet; 

 but care must be taken not to allow the 

 water to stand for any length of time in 

 the saucers. Plants in rooms during the 

 winter months, when grown in a tempera- 

 ture of 50 degrees, will not usually re- 



PER 



quire water more than twice a week, and 

 in the temperature of 65 degrees perhaps 

 thrice a week; but in no case water un- 

 less the lightness of the color of the soil 

 on the top gives indications that the plant 

 is dry, and then water sufficiently to go 

 through the pots; those that seem less dry 

 water more sparingly, and those that are 

 wet give none whatever until they be- 

 come dry, no matter how long the time 

 may be. As plants grown in rooms have 

 only one side to the light, it will conduce 

 to the health and symmetry of the plant 

 to turn it around at least once a week, so 

 that each side will have a like proportion 

 of light 



Parvus. Small; applied relatively, where 

 some object is small by comparison with 

 similar objects. 



Patens, Patent. Spreading wide open, as 

 petals from the calyx. Patentissimus is 

 spreading open so much as to fall back. 



Patulus. Slightly spreading. 



Pedate. A modification of the palmate leaf, 

 when its lower lobes are again divided 

 and directed downwards, as in Saxifraga 

 pedatifida. 



Pedicel, Pedicide, (adj. PedicilMe, Pedicu- 

 late. } A peduncle of a second or higher 

 order, as in the raceme, where the prin- 

 cipal flower stalk is the peduncle, and 

 the lateral secondary ones are pedicils. 

 Pediculus antherce is the filament of the 

 stamen. 



Peduncle. The common stalk of flowers. 



Peltate. Attached by the middle, as the 

 leaf of Tropceolum. 



Penciled. Marked in lines, as if with a 

 pencil. 



Pentagynoiis. Having five styles. 



Pentandrom. Having five stamens. 



Perennial, Perennans, Perennis. Lasting 

 many years, yet flowering, every year.
