tage. The new "everblooming" poker-plants are likely to be listed 

 under this name. K. Pfitzerii, Hort. (K. grandiflora multiflora, 

 Hort.). Described as in bloom from Aug. to Oct., with spikes stand- 

 ing 3-4 ft. high, the fls. rich orange-scarlet. K.ruvaria, Hort. Gar- 

 den hybrid between K. rufa and K. Uvaria (Sprenger, Naples). 

 K. sulphured, Hort. Free-flowering, sulfur-yellow. K. tricolor, 

 Hort. Small-fld.; buds opening cochineal-red, changing to canary- 

 yellow and then to sulfur-white. K. vomerensis, Hort. Garden 

 hybrid (Sprenger, Naples) between K. pauciflora and K. rufa. 

 K. Woddii, Campbell. Resembles K. modesta, but is stouter and 

 there are a few spines on the Ivs. : peduncle 8^2 ft., the raceme 9 in. 

 long; fls. /^in. long, pale cream-color. S. Afr.

KNOWLTONIA (Thos. Knowlton, 1692-1781, curator 

 of the botanic garden at Eltham, England). Ranun- 

 culacese. By some referred to Anemone, but differs in 

 having 5 sepals and numerous petals, and the carpels 

 soft and fleshy: species 8 or so in S. Afr., sometimes 

 mentioned as half-hardy or as greenhouse subjects, but 

 apparently not in the trade. Stemless perennial herbs, 

 with large ternately decompound rigid radical Ivs., no 

 involucre, numerous 1-seeded carpels which become 

 thick and juicy at maturity, and greenish or yellowish 

 fls. on branching cymose or umbellate scapes. K. vesi- 

 catoria, Sims, with Ivs. 1 ft. or more across, green fls. 

 and blackish purple berries: If.-segms. nearly entire or 

 only serrulate: ovaries as long as the subulate style. 

 B.M. 775. B.R. 936. K. rigida, Salisb., with Ivs. rather 

 smaller, segms. sharply serrate, and ovaries shorter 

 than the subulate style: variable. H.F. II. 7:72.

KOA. A species of Acacia (A. koa, page 186), from 

 the wood of which the Hawaiians make their beauti- 

 ful highly polished "calabashes." 



KOCHIA (after W. D. J. Koch, 1771-1849, professor 

 of botany at Erlangen; wrote a flora of Germany and 

 Switzerland). Chenopodiaceae. SUMMER CYPRESS. 

 MOCK CYPRESS. This includes two hardy annuals, 

 called the "mock cypress" or "summer cypress," 



2041. Kochia trichophylla ; often grows in a more ovoid form. 



grown for the compact habit and the herbage which is 

 green in summer and turns red in autumn. 



Kochia is a polymorphous genus of herbs which are 

 often woody at the base : Ivs. often minute and narrow, 

 alternate, more or less silky, rarely glabrous: fls. small 



or minute, sessile, solitary or clustered in the axils of the 

 Ivs.; calyx enlarging into a flask-shaped body, which 

 incloses the fr.; perianth orbicular; lobes 5, incurved 

 and bearing horizontal wings on the back or on the 

 tube which are membranous or scarious, distinct or con- 

 fluent; stamens 5; filaments short or long and com- 

 pressed; stigmas 2, rarely 3. Species 30-40, of which 

 one is native in the W. U. S. and the others in the Old 

 World and Austral. 



The seed may be sown indoors in April, and the plants 

 set out in May, or the seeds may be sown in the open 

 ground about May 1. The plants should stand about 

 2 to 3 feet apart. 



scoparia, Schrad. BELVEDERE. Annual, erect, 3-5 

 ft., much-branched, more or less pyramidal: branches 

 striate, slender, and close to the main st. : Ivs. linear- 

 lanceolate, 2-3 in. long, 2-4 lines wide: fls. inconspicu- 

 ous, green, in elongated clusters; perianth in fr. pro- 

 vided with very short, triangular, pointed appendages. 

 Cent. Eu. A plant sometimes grown in gardens for 

 its fastigiate or pyramidal form; used sometimes for 

 brooms. Probably not now grown to any extent in 

 American gardens. 



trichophylla, Stapf. Fig. 2041. The common summer 

 cypress of gardens, although frequently grown under the 

 name of K. scoparia, but differing in its ovoid, conical 

 or nearly globular rather than narrow and fastigiate 

 form, by its purple-red color in autumn, and other char- 

 acters: annual, very much branching, 3-5 ft., making 

 a very compact ovoid object, remarkable for the natural 

 regularity in different plants: Ivs. very abundant, 

 alternate, straight, long and linear (2-3 % in- long), 

 sharp-pointed, bright green, puberulent and with long 

 white hairs on the margins near the base: infl. in few- 

 fld. glomerules; fls. polygamous, those on the lateral 

 branches most numerous and female, those at the 

 summit of the principal branches perfect: foliage deli- 

 cate green, becoming deep red-bronze in autumn. 

 China, probably. R.H. 1907, p. 119. J.H. III. 66:495. 

 Very useful when formal regular effects are desired, 

 and for its pronounced color in autumn, keeping its 

 shape when most other garden vegetation is destroyed 

 by frost. It is of the easiest cult. This species has been 

 recognized and has come into prominence within the 

 past ten or twelve years. L H. B. 



KOELERIA (G. L. Koeler, professor at Mainz, an 

 early writer on grasses) . Graminese. Tufted perennials, 

 with slender sts. : spikelets 2-4-fld. in dense spike-like 

 panicles. Species about 12, in temperate regions of 

 both hemispheres; of little horticultural value. 



cristata, Pers. Culms 1-1 % ft-, puberulent below 

 the panicles: Ivs. fine, mostly basal. Dept. Agric., Div. 

 Agrost. 20:136. Prairies, N. Amer. Sometimes cult, 

 for lawn decoration in open dry ground.

KOELLIA: Pycnanthemum. 



KOELLIKERIA (Professor Koelliker, German bota- 

 nist). Gesneriacese. One species, a small herbaceous 

 warmhouse plant, K. argyrostigma, Regel, Cent. Amer. 

 to Peru, offered abroad: in the way of achimenes, but 

 fls. smaller in leafless racemes, the corolla-limb dis- 

 tinctly 2-lipped: rhizomatous or the root, creeping: Ivs. 

 opposite, soft-pubescent, elliptical and nearly or quite 

 obtuse, velvety green and marked with white dots: fls. 

 white or cream- color, red-spotted, in racemes standing 

 12 in. high; calyx-tube obovoid, the lobes 5 and nar- 

 row; corolla-tube short, broad and decurved; upper lip 

 2-parted and nearly erect; lower lip larger, 3-parted, 

 spreading; stamens attached in base of corolla, some- 

 what exserted; style filiform, the stigma becoming 

 2-lobed: caps. 2-valved. B.M. 4175 (as Achimenes 

 argyrostigma). Requires treatment probably of achi- 

 menes; prop, by division. L. jj. B.
