ARCTOTIS (Greek for bear's ear, alluding to the 

 achene). Composite. Herbs with long-peduncled heads 

 and more or less white-woolly herbage, of 30 or more 

 African species: achenes grooved, with scale-like pappus: 

 involucre with numerous imbricated scales: receptacle 

 bristly, — Two species, both treated as annuals, are sold 

 in this country. Cultivation simple. 



breviscapa, Thunb. (.4. leplorhhza var. breviscapa, 

 DC). Stemless or nearly so (6 in. high), half-hardy, read- 

 ily prop, from seeds, and to be grown in a warm, sunny 

 place: lvs. usually longer than the scape, incised-den- 

 tate: scape hirsute, bearing one large fl. with dark 

 center and orange rays.

 ing a bushy clump 2-2 '2 ft. high: lvs. much shorter 

 than the scape, repand dentate: fls. 2^2-3 in. diam.,

ARCTOUS (Greek, boreal, referring to its distribu- 

 tion). Syn. Mairania. Ericacese. Ornamental flat 

 shrub, rarely cultivated in rockeries for its bright 

 green foliage and scarlet or black fruits in autumn. 



Prostrate glabrous shrub: lvs. alternate, serrate, 

 deciduous: fls. in small terminal racemes; calyx 4-5- 

 partcd; coroUa urceolate with 4-5-toothed recurved 

 limb; stamens 8-10, included, anthers with a pair of 

 short awns, cells opening with a pore; ovary 4-5- 

 celled: fr. a globose juicy drupe with 4-5 separate 

 nutlets. — One circumpolar species. 



This is a plant lying flat on the ground, with 

 shreddy bark, thin deciduous leaves clustered toward 

 the end of the branches, small white flowers appearing 

 before or with the leaves, followed bj- lustrous, black 

 or red fruits. Adapted for rockeries where it will prob- 

 ably succeed best in peaty soil and in a half-shady posi- 

 tion. Propagation is by seeds and by cuttings. 



alpinus, Niedenzu (Arctostdphylos alpina, Spreng. 

 Mairania alpina, Desv.). Lvs. obovate or oblanceolate, 

 narrowed into the short petiole, I4~^yi in. long, reticu-

 Fr. bright red, not changing to black. Rocky Mts., W.

 account of the bright color of the fr.

ARDISIA (pointed, alluding to the stamens or 

 corolla-lobes). Including Jcacdrea. Myrsinacea?. Trees 

 and shrubs, some of which are grown in their juvenile 

 state as pot subjects, or as outdoor specimens in warm 

 climates. 



F^lowers white or rose, usually in cymes, with 5- 

 parted (sometimes 4- or 6-parted) rotate corolla, 5 

 stamens attached to the throat of the corolla, with very 

 large anthers and a 1-seeded drupe the size of a pea: 

 lvs. entire, dentate or crenate, thick and evergreen.^ 

 Probably more than 200 species in the tropical and 

 subtropical parts of both hemispheres, one of which 

 (.4. cremdala) is a popular berry-bearing conservatory
