somewhat grown for ornament, al^o appears to be of 

 this species. The curious lobinj; of the Ivs. on the 

 young growth is shown in the upper spray of Fig. 1433. 

 The nearest approach to this lobing is in the Japanese 

 {Morns Japoriicn), and this affords another of those 

 interesting parallelisms which exist between the Jap- 

 anese and eastern American floras. The red ]\Iul- 



or calyptra (c) wliich is sljed at maturity. The capsule 

 opens by means of a lid or operculum (o), and tiif^ ori- 

 fice is usually guarded by one or two rows *d' teeth or a 

 peristome. None of the Mosses 

 are horticultural plants, al- 

 though Sphagnum Moss is 

 much used as a packing ma- 

 terial and for hohling moisture 

 about pots, and as a medium in 

 which to sow delicate seeds. It 

 is collected from liogs. Club 

 Mosses are not true Mosses, but 

 lycopodiums (wliicli see). Tlie 

 "Moss" on fruit and other trees 

 is mostly lichen. The Florida 

 or Spanish Moss is a flowering 

 plant (see Tillnndaia). lj-j.b

MOSS. A general name for many 

 humble green plants of the crypto- 

 gamia (flowerless plants), mostly 

 with distinct stems and foliage V 



leaves. In North America there 



are about 1,200 species, di.stributed in numerous fami les 

 and four orders. They have solitary, mostly stalked 

 spore-cases or capsules arising from the apex of a leaty 

 stem (Fig 1434). The capsule is covered with a thin cap 



MOULDS. The term Mould is generally applied to any 

 small fungous growth which appears on decaying organic 

 matter, such as fruits, both fresh and preserved, vege- 

 tables, etc. Tlie Moulds are very simple fungi producing 

 immense numbers of spores, a fact which accounts for 

 their presence everywhere, in the air, in dust, and on all 

 exposed bodies. As a rule these fungi are not directly 

 injurious to plants; they are normally saprophytes and 

 perform a great service in disorganizing organic matter 

 which would otherwise accumulate on the earth. A 

 few of the species may become parasitic. Thus, species 

 of Botrytis often attack lettuce in forcing-houses which 

 are too close and damp. Carnation buds and violet plants 

 are also frequently injured by Botrytis. The mould- 

 like growths occurring on boards in damp cellars or in 

 greenhouse benches are sterile mycelia of higher fungi. 

 These do not attack plants, but sometimes, as in the case 

 of violets, grow over and smother the plants. (See also
