MUSTARD 



MYOSOTIDIUM 



following spring. Some of the large-leaved forms of 

 Chinese mustard (B. juncea, Fig. 635) are excellent, and 

 should be better known. One of the oriental species 

 (B. napiformis) makes an edible turnip-like root (Fig. 

 632, Vol. I). Mustard needs a rich quick soil for the 

 producing of the best foliage. Sow the seeds in drills 

 1 foot or more apart, and thin to 6 niches in the row. 



L. H. B. 



MUTISIA (named after Jos. C. Mutis, 1732-1808 or 

 1809, botanist of South America). Composite. Showy- 

 flowered shrubs, those in cultivation being tendril- 

 climbers; greenhouse or planted out. 



Erect or scandent, in cult, likely to be herbaceous, 

 glabrous or tomentose: Ivs. alternate, simple or pinnate, 

 the midrib usually produced into a tendril: heads 

 large, heterogamous, usually long and the involucre 

 cylindrical or campanulate, solitary on the ends of 

 branches, the few rays purple, rose-colored or yellow; 

 ray-florets in one series, pistillate; disk-florets herma- 

 phrodite, fertile or sterile; receptacle naked, nearly flat: 

 achene angular, turbinate or oblong, crowned with 

 rigid plumose pappus bristles in one series. Species 

 about 60, in S. Amer., tropical and extra-tropical. The 

 mutisias have never been popular, although long 

 known to cult. They are plants of attractive habit and 

 showy heads. Some of the species need warmhouse 

 treatment, but the following require cooler treatment, 

 and are probably adaptable to growing permanently 

 out-of-doors in the southern limits of the country. 

 Prop, by cuttings. 



A. Lvs. pinnate. 



Clematis, Linn. f. Climbing herb, rather woody, 

 woolly-pubescent: Ivs. pinnate, the rachis extended 

 into a tendril; Ifts. 4-5 pairs, short-stalked, oblong- 

 lanceolate, mucronate, entire: heads long-pendulous, 

 oblong-cylindrical, nearly 3 in. long and more than 2 

 in. across the rays, the latter 9-10, bright red, recurved. 

 Trop. Andes. B.M. 8391. G.C. III. 45:415; 54: 

 suppl. Nov. 29 (colored). A very vigorous grower, 

 making a good cool greenhouse climber. 



AA. Lvs. simple. 



ilicifolia, Cav. Climbing slender shrub glabrous or 

 cobwebby: Ivs. 1-2 in. long, sessile, cordate or auricled 

 at base, oblong, spiny-toothed and stiff, bright green 

 above, the apex of the blade truncate or 2-lobed, the 

 tendril stout: heads peduncled and solitary in the axils, 

 3 in. diam., the 8-12 rays pale pink or purplish (pale 

 mauve as described by some). Chile. B.M. 6009. 

 G.C. III. 50:449; 54:383. The ilex-like foliage is 

 interesting. 



decurrens, Cav. Climbing, the sts. somewhat 

 branched, glabrous: Ivs. remote, oblong-lanceolate 

 and entire, acuminate, dark green above and glaucous 

 beneath, tendril bifid, the base of the blade decurrent: 

 head solitary, 4% in. across, the rays brilliant orange. 

 Chile. B.M. 5273. F.S.23:2408. G.C. 111.50:451, 452. 

 Gn.W. 24:784. Perhaps the best species, L. H. B. 



MYALL: Acacia. 



MYOPORUM (Greek words referring to the trans- 

 lucent resinous dots in the leaves). Myoparacese. Cool- 

 house shrubs, more or less heath-like, grown for the 

 small white or purplish flowers; some are trees. 



Erect and tall, or diffuse, glabrous or glutinous: Ivs. 

 alternate, rarely opposite, entire or toothed, with pel- 

 lucid glands: fls. axillary, usually clustered, small or 

 medium-sized, mostly white; calyx 5-cut or 5-parted; 

 corolla somewhat bell-shaped or funnel-shaped, the 

 tube very short or long; lobes usually 5, nearly equal or 

 the anterior perhaps larger; stamens 4, or sometimes 

 5-6; ovary 2-10-celled : fr. a small more or less succulent 

 drupe. Species 25-30, Austral.. New Zeal., China, 

 Japan, Pacific Isls. The genus is divided by Bentham & 



Hooker into 5 sections based on the shape of the fls., the 

 number of the corolla-lobes and stamens, and the num- 

 ber of cells in the ovary. Usually the calyx-segms. are 

 small and narrow, but in one section they are leafy. 

 One of the species (known in cult, as M . parvifoliurri) 

 was once a favorite heath-like plant in France. In 1883 

 it was stated in the Garden that for 20 years many 

 thousand plants of it had been sold annually in the flower- 

 markets of Paris. One grower always had a stock of 

 30,000 plants. The plants were grown in small pots for 

 room and window decoration in spring. "It is most 

 beautiful as seen with its pale green branches drooping 

 gracefully around the pot sides, and more especially so 

 when the shoots are wreathed with sweet, snow-white 

 blossoms." Prop, by cuttings taken in spring. This 

 species is practically unknown hi Amer. Some of them 

 are said to be useful in Calif . for planting near the sea- 

 coast. The American gardener may get some general 

 suggestions from the experience recorded under 

 Epacris and Erica. 



A. Tree of some size. 



sandwicense, Gray. BASTARD SANDALWOOD, from 

 the sandalwood odor of the wood. NAIO. "A very 

 handsome tree which reaches a considerable size" 

 (Rock) : Ivs. crowded toward the ends of the branches, 

 alternate, elliptic-lanceolate or oblong-lanceolate, acute 

 or acuminate, fleshy when growing at the seacoast or 

 low elevations, to 6 in. long, entire or serrate, the young 

 ones viscous: fls. white or deep pink, in clusters of &-8: 

 drupe dry or somewhat fleshy, globose or ovate, white.

 diam., almost globular. Austral.; cult, in Calif. 



serratum, R. Br. Erect or somewhat diffuse shrub, 

 usually glabrous, exceedingly variable: Ivs. elliptic- 

 oblong or lanceolate, obtuse or acute, more or less ser-

M. -plctum and M. verrucdsum are mentioned in lists, but thek 

 botanical standing is uncertain. WlLHELM MlLLER.
