 or yellowish: fls. white, %in. across; ovary bottle- 

 shaped: fr. yellow, bitter. June. Japan, Korea, Man-

 young branchlets and Ivs. bright red; pith of branches 

 lamellate: Ivs. orbicular or oval, cordate, firm, 3-5 in.

 beautiful of the actinidias with the largest fls. and a 



promising fruiting vine; the frs. have the flavor of a 

 gooseberry. 



A. collosa, Lindl. Similar to A. Kolomikta. Branchlets with con- 

 spicuous lenticeU, with lamellate pith: Ivs. oval to oblong, 3-5 in. 

 long, serrulate, quite glabrous: fls. white, H in- across: fr. ovoid, 

 spotted, 1 in. long. China. A. corvicea, Dunn. Allied to the pre- 

 ceding species. Lvs. coriaceous, oblong to lanceolate, remotely ser- 

 rate, 31 in. long; petioles less than 1 in. long: fls. several, reddish: 

 fr. ovoid, spotted, H~%in. long. China. Recently offered under 

 the name of A. Henryi, which is a totally different species, allied 

 to A. chinensia. A. melandndra, Franch. Allied to A. arguta. Lvs. 

 ovate-oblong or oblong, closely serrulate: staminate corymbs 

 many-fld.; petals greenish at the base: fr. purple. China. 



ALFRED REHDER. 



ACTINOLEPIS (Greek, a scale-like ray). Composite. 

 About 6-8 species of hardy annuals, mostly from Calif.; 

 freely branching, and mostly yellow-fld. The fla. are 

 in pedunculate heads at the tips of the branches; rays 

 usually 2-3-toothed, in one series: Ivs. opposite. Con- 

 sidered by da Delia Torre and Harms to be a sec- 

 tion of the genus Eriophyllum, and by Gray to belong 

 properly to Baeria. 



coronaria, Gray (Shortia californica, Hort. Baeria 

 coronaria, Gray). Fig. 116. Lvs. opposite, except the 

 upper ones, 2 in. or more long, pinnately, or the lower 

 ones bipinnately, parted into linear, narrow divisions: 

 pappus of awned or of muticous, often erose palese, 

 rarely wanting. B.M. 3828 (as Hymendxys californica). 

 One of the prettiest of annual fls., and deserving of 

 greater popularity. Excellent for edging. An everlasting.

ACTINOMERIS (from Greek aktis, ray, and meris, 

 part, alluding to the irregularity of the rays). Com- 

 pdsitx. Native hardy herbaceous perennials suitable 

 for wild gardens and shrubbery. 



Tall, branching, yellow-fld. herbs, with aspect of 

 native sunflowers, but with smaller fls.: Ivs. often 

 decurrent on the stem: fls. in corymbose or solitary 

 heads, composed of both ray and tubular fls. Cult, 

 like Helianthus. Prop, by division. 



squarrosa, Nutt. (Verbesina alternifblia, Linn.). 

 Height 4-8 ft. : Ivs. lance-oblong, acuminate, toothed, 

 subpetiolate, tapering to both ends: fls. numerous, 

 corymbed, yellow, 1-2 in. across.; rays 2-10, irregular. 

 Autumn. E. N. Amer. 



A. helanthoides, Nutt. (Verbesina helianthoides, Michx.). Lvs. 

 silky villous underneath: rays about 8, usually more than in A. 

 squarrosa. Mn. 4:129. A. prdcera, Steud., is only a taller form 

 of A. squarrosa. N TAYLOR.t 



ACTINOPTERIS (aktis, ray, and pteris, the leaves 

 radiately cut). Syn., Actinidpteris. Polypodiacex. 

 Greenhouse ferns from India, resem- 

 bling miniature fan-palms. The sori are 

 linear-elongate and submarginal, and 

 covered with indusia. A. radiata, Link 

 (A. austrdlis, Linn, f.) is the only recog- 

 nized species. Apparently not in the 

 horticultural trade. 



ACTINOSTEMMA (ray and wreath 

 or stems). Cucurbitacex. Three or 4 

 species of climbing or running plants 

 from China and Japan, of which A. 

 paniculatum, Maxim., has been grown 

 in European collections. It is a hardy 

 perennial in Cent. Eu., with tuberous 

 roots, palmate Ivs. and small fls.; said n6. Actinolepis

Pseudobulbs elongated, bearing at the apex 1-3 

 coriaceous Ivs.: fls. nodding, in a somewhat 1-sided 

 raceme, terminating the lateral leafless scape; sepals 

 nearly equal, free, usually spreading above; petals 

 similar to the sepals but smaller; lip sessile, continuous 

 with the base of the column, entire, shorter than the
