FRAME 



FRAME. Fig. 865. A box witliout permauent top or 

 bottom which i.s designed, when covered with glass or 

 other transparent material, as a place in which to grow 

 plants. "When supplied with artificial bottom heat, the 

 frame is part of a hotbed; when supplied only with sun 



heat, it is part of a coldframe. The Frame may be of 

 any size, but the normal size is 6 x 12 ft., an area which 

 accommodates four 3x6ft. sashes; and this Cxl2 area is 

 understood when one speaks of "a Frame." See Hot-

 Sasi(raijflce(p. Three species of Chilean perennial 

 herbs, with turnip-like (lyrate) Ivs. and terminal, dense 

 racemes of white or pink fis. V)orne in summer. They 

 are interesting as liaving points in common with Cras- 

 sulaceae, Rosacepe, Galax and even Dionrea. They grow 

 about 2 ft. high, and in the North could perhaps be win- 

 tered in a coldframe. Scape-bearing, glandular-pilose 

 or tomentose: rhizome thick, many-headed: Ivs. glan- 

 dular-dentate: fls. 1 in. across, as many as 36 in racemes 

 6 in. long: floral parts in 4's, rarely ."i's; petals obovate, 

 clawed. 



A. Fls. white. 



ramdsa, D. Don. Taller, woodier and more 

 branching than the others, and distinguished 

 by pubescent inflorescence. Leaf-stalks not 

 margined: fls. smaller. Hardy at Washington, 

 D. C, according to J. Saul, with spikes 2 ft. 

 long and 1 in. thick. 



AA. Fls. mostly pink. 



B. Leafstalks broadly winged at the base. 



sonchlfdlia, Cav. Lower lobes continuous with 

 the broad margin at the base of the leaf-stalk: 

 petals deep rose, dark-spotted. B.M. 3309. 



BB. Leaf-stalks not winged at the base. 



appendicuiata, Cav. Lower lobes distant from the 



base of the stalk : petals pale rose, rarely spotted. B.M.

constantly kept in a greenhouse, especially if it be 

 planted in the open soil, where it can be freely exposed 

 to light and air, without which the beautiful spots of its 

 petals are scarcely developed." His plate shows 4 pretty 

 red spots near the base of each petal. L.B.C. 19:1864, 

 erroneously named F. sonchifolia, has the midveins and 

 bases of the side veins of the petals dark red. \^r ^^

FRAXINUS (ancient Latin name). Oledcei^. Ash. 

 Hardy ornamental trees, with deciduous, opposite, pin- 

 nate, rather large lvs. ami small fls. in panicles, either 

 appearing before the lvs. and greenish, or in the subge- 

 nus Ornus after or with lvs. and whitish in showy pani- 

 cles : the winged fr. is insigniticant. They are valuable 

 as street and park trees, and grow mostly into tall, pyr- 

 amidal or broad-headed trees, with rather light green 

 foliage, which turns yellow or dark purple in fall or re- 

 mains green, as in F. eseelsior and O'nius. The Ash is 

 seldom severely injured, though a number of insects 

 and fungi prey on tlie lvs. and wood, of which two borers, 

 and a fungus attacking the lvs., are perhaps the most 

 obnoxious. Most of the species are hardy North except 

 those from the southern states, southern Europe and 

 Himalayas ; of the sub-genus Ornus, F. Bungeana and 

 F. longicnspis seem to be the hai'diest. The Ashes are 

 important forest trees, and the straight-grained and 

 tough wood is much used for handles of tools, in the 

 inauufacture of carriages and wagons, for the interior 

 finish of houses, and for furniture, for baskets and also 

 for fuel. From F. Ornus manna is obtained as an exu- 

 dation of the trunk, and some Chinese species yield the 

 Chinese white wax. The Ashes grow in almost any 

 moderately moist soil, F. nigra being somewhat more 

 moisture-loving, while F. oxycarpa,F. Ornus, F. Sogdi-
