Mariscus 



(56) 



Martynia 







MARISCUS. 



A large geuus (ord. Cyperaces), but horticultural!}- 

 an unimportant one. Umbilensis (si/ns. Cyperus 

 natalensis of gardens, and urubiliensis) may be 

 treated in the same way as Cyperus alteriiifolius. 



MARL. 



A clayey soil which contains a considerable 

 quantity of carbonate of lime. When cultivated, a 

 marly soil is fertile, but iu periods of wet weather 

 its greasy, slimy nature renders it exceedingly 

 difficult, if not impossible, to work. Marl is occa- 

 sionally employed as a dressing for land deficient 

 in lime. 



MARLEA (ay HI. PSEUDALANGIUM.RHYTID- 

 ANDBA, STYLIDIUM, and SIYLIS). 



Greenhouse trees and shrubs (ord. Cornacea:) 

 with white or yellow flowers in clusters borne in 

 the axils of the leaves. Of the four or five species 

 included, one only, begonisefolia, is. at all well 

 known. It may be increased by cuttings of side 

 shoots, rooted in sand iu a close, warm frame, and 

 likes a compost of pjat and sandy loam in equal 

 parts. 



Principal Species : 



begonitefolia, 00', sum., grh., yel., wh., a tall ev. 

 tree. 



MARROW, VEGETABLE {we Cu 



CUBBITA PEPO for species and VEGETABLE 

 MARKOW for culture and varieties). 



MARRUBIUM. (HORBHOUND.) 

 There are upwards of thirty species in this 

 genus (ord. Labiatic), but one only, vulgare, is of 

 moment.' This is a useful herb, described under 

 HOREHOUND (which see). Most of the Marrubiums 

 are woolly, and the flowers are some shade of white 

 and pink. Propagation, by cuttings and root divi- 

 sion, for all are hardy perennials. Ordinary garden 

 soil. . 



MARSDENIA (syns. LEICHARDTIA and 

 SICYOCABPUS). 



Stove, greenhouse, and half-hardy twining or 

 sub-erect shrubs (ord. Asclepiadere). The flowers 

 are pretty, rather smaller than those of Stephanotis, 

 but the plants are not common in cultivation. 

 Cuttings may be rooted in sand under a bell-glass, 

 in heat, during April and May. Soil, two parts 

 loam, one part leaf mould, and enough sharp sand 

 to render it porous. 



Principal Species : 

 Cundurango, sum., st. 



cl., wh. (//. Gouolobus 



Cundurango), 

 erecta, 3' to 20', Jy.,hlf- 



hdy. sub-erect shr.,

Marjoram (see Herbs and Origanum). 

 Marmalade Plum (see Liicuma). 

 Marquisia (see Coprosma}. 

 Itarrubiastnim (see SideriUs). 



MARSHALLIA (syns. PERSOONIA, of 

 Michaux, Therolepta, and Trattenika). 



Hardy perennial herbs (ord. Composite), with rose 

 or purple flowers resembling those of a Scabious. 

 Seeds may be sown out of doors on a warm border, 

 about mid-April. A light garden soil is to be 

 preferred. 



Principal Species : 



csespitosa, 1', Je., hdy., bl., wh., heads H" across. 



MARSILEA. 



A small genus (urd. Marsilea;) of greenhouse 

 sub-aquatics, interesting to the botanist as link 

 plants, being closely related to the Ferns, and 

 always included in the plants spoken of as " Fern 

 Allies," along with the Equisetums, the Selaginellas, 

 and the Lycopodiums. The spore cases (sporangia) 

 are edible, and are occasionally used by the natives 

 of Australia as food. The plants may be grown in 

 pots in loam and leaf soil, their chief requirement 

 being plenty of water at all seasons. If they can 

 be stood in water, so much the better. The 

 resemblance of the silky fronds to Trifolium leaves 

 causes them to be frequently mistaken for Sham- 

 rock. The plants may be increased quite readily 

 by division. 



Principal Species : 



Drummondii, 4" to 8", vatrix is a var. of 

 grh., leaflets thickly Drummondii. 



clothed with silky hairs hirsute, 4" to 7", grh. 

 (XI/H. macropus). Sal- quadrifolia, a hdy. creep- 

 ing aquatic. 



MARTINEZIA (/, AIPHANES). 



Rather dwarf-growing stove Palms (on?. Palmss) 

 of elegant appearance. The leaves are pinnate, 

 and the pinnre wedge shaped, with jagged margins. 

 Propagation, by imported seeds. Soil, sandy 

 loam and peat in equal proportions. Plenty of 

 heat and an abundance of water, both at the root 

 and in the atmosphere, are necessary. Liquid 

 cow manure is the best stimulant. Potting should 

 be firm, to retain the plants in small pots, and 

 enhance their decorative value. 



Principal Species : 



caryotapfolia, Ivs. 3' to 4' needle-like l>r. spines, 



long, dark grn., spines leafstalks mealy, 



blk. The handsomest granatensis, spines I" to 

 of all. 1" long, br., usually 



erosa, stem and Ivs. bent, 



covered with strong, lindeniana, 16', bright 



gru., spines blk. 

 Other Species : 

 Aiphanes, 30', Ivs. o' long {"//M. Aiphanes aculeata). 



MARTYNIA. 



Greenhouse annuals or perennials (ord. Pedalin- 

 eas), with tuberous rootstocks. Fragrans, com- 

 monly cultivated, is an annual with large, showy 

 flowers, and of easy culture in a greenhouse. 

 Seed should be sown in spring in a gentle heat, 

 the seedlings being potted on in a mixture of
