MARTYNIA (named after John Martyn, F.R.S., 

 1699-1768, once Professor of Botany at Cambridge, 

 author of "Historia Plantarum Variorum"). OED. 

 Pedalinew. A genus comprising about ten species of 

 erect or prostrate, clammy-pubescent, greenhouse herbs, 

 sometimes annual, sometimes with a large tuberous 

 perennial root, natives of the warmer regions of I 

 America. Flowers pink, violet, or pale yellowish, in 

 short terminal racemes; corolla tube oblique or decnrved 

 at base, limb with five spreading lobes. Capsule sab- 

 drupaceous, terminating in two curved beaks or hooks

(see Fig. 517). Leaves opposite or alternate, long-stalked, 

 cordate, thickly sinuate-toothed or palmately lobed. The 

 best-known species is M. fragrans. This thrives in well- 

 drained porous soil, in a warm, sheltered situation. 

 Seeds should be sown, during the early part of spring, 

 on a gentle hotbed, or in a warm, moist greenhouse, 

 and the seedlings transferred to the open border about 

 the latter part of June ; or they may be grown on in 

 pots for greenhouse decoration, if desired. The other 

 species require similar treatment. All those described 

 below are annuals. 

 M. anuua (annual). A synonym of M. proboscidea. 



Martynia continued. 



M. dlandra (diandrous). /., thyrsoid in the forks of the stem, 

 drooping; corolla with a white tube, tinged with purple, and 

 spotted with red and yellow ; limb pale red, with a shiny purple 

 spot at each segment. July. 1. opposite, lobed, cordate at the 

 base, villous and viscid. Stem branched, h. 2ft. Mexico, 1731. 

 (A. B. R. 575 ; B. R. 2001.) 



M. fragrans (fragrant).* ft. crimson-purple, with a yellow throat, 

 large, fragrant, disposed in handsome spikes. Summer and autumn. 

 fr. very singular, prolonged upwards into two curved, sharp, 

 hooked horns, Sin. to 4in. long. I. large, Ions-stalked, cordate, 

 angled, coarsely-toothed, h. 2ft. Mexico, 1840. If gathered 

 when very young, the fruit is said to make an agreeable pickle 

 in vinegar. (B. M. 4292 ; B. R. xxvii. 6.) 



M. lutea (yellow), fl. orange-yellow, suffused with blood-colour 

 inside, large, funnel-shaped. August. 1. opposite, cordate-orbicu- 

 lar, toothed, clothed with glandular down. Stem branched, 

 downy. A. 1ft. to 2ft. Brazil, 1825. See Fig. 517. (B. R. 934. v

 Portion of Inflorescence. 



M. proboscidea (proboscis-like).* fl. with a yellowish- white tube, 

 variegated with green, yellow, and violet spots and lines ; limb 

 wide, pale violet, marked with saffron-coloured and violet dots 

 and lines. July. I. alternate, lobed, cordate at the base. Stem 

 branched, h. 1ft. to 3ft. Mexico, 1738. SYN. M. annua. See

 MARYGOLD, See Marigold. 

 MASCARENHASIA (from the Mascarene Islands, 

 where it is found). OBD. Apocynacece. This genus com- 

 prises about four species of stove shrubs or small trees, 

 natives of Madagascar. Flowers whitish-purple, sub-sessile 

 in the nodes, fasciculate or sub-solitary, terminal, or in 

 one species scarcely axillary, large ; calyx small, five- 

 parted, the segments ovate or narrow; corolla salver- 

 shaped, the tube cylindrical, the throat contracted; lobes 

 five, ovate, twisted. Leaves opposite. For culture of 

 the under-mentioned species, see Dipladenia. 

 M. Curnowiana (Curnow's).* fl., corolla scarlet, glabrous ; tube 

 in. long, swollen above ; lobes nearly lin. long, ovate-lanceolate, 

 acuminate ; calyx of five subulate, erect teeth, much shorter than 

 the corolla tube ; cymes terminal, few-flowered ; peduncles rather 

 longer than the petioles ; pedicels shorter. August. I. opposite, 

 Sin. to 4in. long, shortly stalked, oblong or oblong-lanceolate, 

 entire, obtusely pointed, the base acute and rounded ; petioles 

 T^in. long. A slender shrub. (B. M. 6612.) 

 MASDEVAIiLIA (named after Dr. Masdevall, a 

 Spanish botanist and physician). ORD. Orchidece. Of this 

 genus upwards of 150 have been described as species. 

 They are cool-house epiphytal Orchids, inhabiting the cool, 

 wooded, mountainous regions of tropical America, from 

 Peru to Mexico, a few being found in Brazil and Guiana. 

 Flowers often beautifully coloured or variously spotted, 

 medium or rather large, borne generally singly, but some- 

 times two or several, on radical stalks; sepals joined 

 into a tube, except at their apices, where they are 

 free, and drawn out into long, narrow tails; petals 

 free, very small, concealed in the tube of the sepals, 

 as is also the lip, which is sessile and articulated
