RESURRECTION PLANTS 



plant could be grown in a window-garden. For his spe- 

 cial purpose the writer has been accustomed to sow 

 seeds in Feb. in 4-inch pots, using a light, sandy soil, 

 in a house with a temp, of G0° F. As soon as the seed- 

 lings are large enough they are transplanted into other 

 4-inch pots, 3 plants to a pot. As to the vitality of the 

 seed the writer can only say that the seeds of Cniciferfe, 

 being mealy, not oily, often retain their vitality for five 

 years <

Many extravagant stati iiients ire made about the 



Bird's-nest Moss. The dried plants offered by the trade 



will turn green and grow unless they are too old or 



have been kept dry too long. They would probably not 



grow if kept over more than one season. They cannot 



be dried again and again indefinitely. 



If aplant has been grown in a pot for three or four years 

 and is then dried off it will die. Most people who grow 



these pla 



place them in a bowl of water 

 with perhaps a little sand and a 

 few pebbles. The water causes 

 thera to turn green and they 

 will grow for a time. Then if 

 taken out of the water they may 

 be kept dry for a time and the 

 process repeated, but each time 

 the plant loses its lower or outer 

 circles of fronds much faster 

 than new ones are made and at 

 about the third time the plant 

 is used up.

can species by the resinous canals nt tin- sreds (from 

 Greek rctine, resin, and sponi, seed). Afterwards tlio 

 genus was united with Chania'cyiiaris, but in horticul- 

 tural nomenclature the name is applied to a number of 

 juvenile forms of Thuya and Chamaicyparis chiefiy in- 

 troduced from Japan. As these juvenile forms all resem- 

 ble each other very much, indeed much more than they 

 do the typical forms to which they belong, it is not 

 strange that they should have been considered to be dis- 

 tinct species and even to belong to a separate genus. 

 Even botanists failed to recognize the true relation of 

 these forms and went as far as to place one of them in 

 the genus Juniperus. With the exception of Uetinispora 

 erjcoi'des, which C. Koch recognized as the juvenile form 

 of Thuya occidentalis , the origin of these juvenile forms 

 remained doubtful until L. Beissner, after having care- 

 fully studied the subject for years, disclosed the rela- 

 tionship of the various forms. He slu.wfd hy experi- 

 ment that it is possible to raise the sani.- f..nii 1,'v nmking 

 cuttings from seedlings which havi' siill ntaimil ilnir 

 primordial foliage, and he also pnMi-li.,.1 ra~. s in 

 which larger plants of these doubtful f..iins bad ln-i-ri 

 observed accidentally to develop branches with the foli- 

 age of the typical form. See, also, Gt. 1879, pp. 109 and 

 172; 1881, pp. 210 and 299, and 1882, p. 152. 



There are 4 of these juvenile forms generally in culli- 

 vation, each of them with an intermediate form showing 

 either a kind of foliage approaching that of the type or 

 two different kinds of foliage on the same plant. There 

 seems to be no doubt that all these forms have been se- 

 ■ plants. 

 ... ■ genera 



of the Cupressinese produce in their juvenile state a kind 

 of primordial foliage very different in appearance from 

 that of the adult plants. The first leaves are alwavs lin- 

 ear and spreading, passing gradually into acicular and 

 at last scale-like leaves. In some plants, especially if 

 they have not sufiicient nourishment, the primordial 

 foliage is retained longer than usual and these have 

 probably been selected for perpetuating the juvenile 

 state, by means of cuttings. By continuing through 

 many generations the propagation of those branches 

 which show the juvenile state most distinctly, these 

 forms have become well-fixed varieties and even some- 

 times bear seeds without changing the foliage on the 

 fruiting branches. These seeds, however, produce 

 plants of the typical form and only a few of them retain 

 the primordial foliage somewhat longer than usual. 



The juvenile forms very much resemble some species 

 of Juniperus in habit and foliage. They bear linear 

 spreading leaves in pairs, changing in winter to a 

 brown, reddish, violet or stcid color, and do not show 

 the regular frond-like bran. Inn- ,,f ili, tvpical forms.
