Matthiola (matthio-la, after Signer Matthioli. Ord. Cruciferae). 

 The only species grown under the generic name is bicornis, the 

 Night-scented Stock (see Annuals), which has lilac flowers that are 

 deliciously scented in the evening. Incana is the parent of the 

 Brompton and i. annua of the Ten-week Stocks. See Annuals and 

 Biennials. 



Maurandia or Maurandya (mauran-dya, after Professor Maurandy. 

 Ord. Scrophularineae) . Climbing plants for the cool greenhouse, or 

 for the pergola or a warm wall outside in summer. Barclayana, 

 with violet flowers in summer; and scandens (syn. Lophospermum 

 scandens), purple flowers in summer, are the best known. The 

 former is illustrated in the Botanical Register, t. 1 108 ; and the latter, 

 as L. scandens, in the Botanical Magazine, t. 3650. They may be 

 raised from seed in heat in spring, and further increased by cuttings 

 under a hand-light in summer. Friable loamy soil suits them. 



Maxillaria (maxilla-ria, from maxillose, insects' jaws, in allusion 

 to the shape. Ord. Orchidaceae) . Terrestrial Orchids with fleshy 

 flowers, suitable for a cool house, thriving in pots in equal parts of 

 peat and chopped Sphagnum moss, and propagated by division in 

 spring. They are great moisture lovers, and like a shady place. 

 Grandiflora, white and red; Lindeniae, white and pink; Sanderiana, 

 white and red ; and tenuifolia, dark red and yellow, are a few of the 

 most popular species.

Mealy Bug (Coccus adonidum). One of the worst enemies of 

 plants. It attacks hothouse, greenhouse, and vinery occupants in- 

 discriminately. The white cottony substance seen is merely a 

 covering, the red insect lies beneath, sucks out the sap, and renders 

 the foliage offensive with its excrement. Regular syringing in 

 summer, with an occasional vaporising by cone, goes far in keeping 

 mealy bug under. Syringing with a paraffin emulsion (see Paraffin) 

 is good where practicable. On emergency the leaves must be 

 sponged. If vineries become infested they must be cleansed, 

 together with the rods in winter. 



Meconopsis (meconop-sis, from mekon, poppy, and opsis, like. 

 Ord. Papaveraceae) . Hardy herbaceous annuals, biennials, and 

 perennials, the most popular of which is cambrica, the Welsh Poppy, 

 a hardy perennial with yellow flowers in summer, i ft. high. Wal- 

 lichii, 3 to 4 ft., blue, summer, is also a good perennial. There is a 

 double form of cambrica called plena. Integrifolia is a splendid
