CLARKIA 



CLAYTONIA 



often toothed, shorter than the rhomboidal limb: 

 caps, stalked. B.R. 1981. R.H. 1864: 151 (?). Not 

 much cult. 



AA. Stamens 4 perfect and 4 rudimentary: Ivs. very 

 narrow. 



pulchella, Pursh. Fig. 980. One ft. to 18 in. high, 

 branchy, often tufted and dwarf, the sts. mostly pu- 

 berulent: Ivs. narrowly lance-oblong to linear, narrowed 

 into a petiole, entire: fls. lilac, running into white vars.; 

 petals %in. or less long in wild plants, with 3 wide- 

 spreading lobes and a pair of recurved teeth on the 

 claw: caps, stalked. B.M. 2918. B.R. 1100. R.H. 

 1845:385; 1886, p. 557. Common in cult. There are 

 semi-double and dwarf forms. Var. holopetala, Voss 

 (C. integripetala, Hort.) is a garden form or race with 

 entire petals. There are also dwarf forms of it. The 

 garden names kermesina and 

 limbata belong with C. pul- 

 chella. L. H. B. 



CLARY* The dried leaves 

 of Salvia Sclarea, which are 

 used for seasoning. Other 

 species of Salvia have been 

 used for the same purpose. 

 See Salvia. 



CLAUCENA (a personal 

 name). Rutdcese. Small 

 inermous trees : Ivs. pinnate : 

 fls. in terminal panicles or 

 loose racemes; ovary raised 

 on a short disk, 4-5-celled, 

 with 1-2 ovules in each cell; 

 style short, deciduous; sta- 

 mens 8-10: fr. 4-5^celled, 

 with usually 1 seed in each 

 cell; cotyledons aerial in 

 germination, first foliage- 

 Ivs. opposite or alternate. 



Lansium, Skeels (Clau- 

 sena Wdmpi, Oliver. Quin- 

 dria Ldnsium, Lour. Cobkia 

 Wdmpi, Blanco). WAMPI. 

 Low spineless tree, with 

 spreading branches : Ivs. 

 spirally arranged, pinnate; 

 Ifts. 5-9, ovate -elliptical, 



3-5 in. long, petiolate, light green, shiny above: fls. 

 4-5-parted, small, white, in large terminal panicles; 

 ovary villous, 5-celled, with 1 ovule in each cell; style 

 short; stamens 10: fr. ovate-globose, about 1 in. long; 

 skin glandular, pubescent; seeds green. The wampi 

 is a native of S. China, where it is commonly grown for 

 its frs. It is cult, to some extent in Hawaii and could 

 probably be grown in the warmer parts of Fla. and Calif. 

 It can be grafted on grape-fruit and other species of 

 Citrus, which makes it desirable to test it as a stock for 

 common citrous frs. WALTER T. SWINGLE. 



CLAVIJA, (Don Jose de Viera y Clavijo, of Madrid). 

 Syn., Horta. Myrsindcese; by Mez separated in the 

 family Theophrastdcese. Thirty and more tropical 

 American evergreen unbranched trees or shrubs, a 

 few of which are sometimes grown in the warmhouse. 

 The sts. are simple, often spiny, bearing at the top a 

 cluster of large rigid, simple, entire or spiny-toothed 

 Ivs.: fls. polygamous-dioecious in axillary racemes; 

 calyx 4-5-parted, the segms. round; corolla white, yel- 

 low or orange, the tube short and fleshy, the limb mostly 

 spreading and 4-5-lobed; stamens 4 or 5, the filaments 

 often united in the sterile fls.; staminodia 4 or 5, 

 being scales in the throat; ovary fusiform, narrowed 

 into a short style, the stigma obtuse or capitate: fr. 

 several-seeded, berry-like. The clavijas thrive in a 



peaty potting soil, and prop, by cuttings of half- 

 ripened growths. They are odd plants. The features are 

 here given as apparently understood by horticulturists. 



A. Lvs. entire, or only repand. 



nobilis, Mez, (C. clavdta, Decne). Plant 4-5 ft.: Ivs. 

 long-petioled thick, 1H ft. or less, elliptic or oblong or 

 oblanceolate, entire, acute or semi-acute: fls. yellow, 

 with a very large disk, %in. long, the corolla fleshy, in 

 drooping racemes 2-4 in. long. Venezuela. B.M. 6928 

 (as C. Ernstii, Hook., f.). 



integrifSlia, Mart. (Theophrdsta integrifolia, Pohl). 

 Allied to C. longifolia, differing chiefly in the less rigid, 

 broader and entire leaves, longer petioles and larger 

 fls. Lvs. distinctly petioled (petioles J^-l in. long), 

 obovate-oblong to lanceolate-oblong, acute and mucro- 

 nate, cuneate at the base, quite entire or slightly 

 undulate, 8-18 in. long: racemes erect, 5-7 

 in. long; fls. larger than in C. ornata, on 

 slenderer pedicels, 5-merous; appendages 

 of the corolla rounded, short. Brazil. 



grandis, Decne. (Theophrdsta macro- 

 phylla, Lind., not Link. T. grandis, 

 O. Kuntze). Lvs. large (to 3 ft.), 

 long -oblong, narrowly pale -margined, 

 entire or sinuate-repand ; petiole thick 

 and dark violet, the secondary nerves 

 slender and simple or forked: fls. orange- 

 yellow, in short and erect racemes; 

 calyx-lobes orbicular and nearly gla- 

 brous, the corona 5-lobed. Colombia. 



AA. Lvs. serrate, often spiny-toothed. 

 longifolia, Mez. (C. ornata, Don, Theo- 

 phrdsta longifolia, Jacq.). Plant 10-20 

 ft. : Ivs. many, in a crowded head or tuft 

 at the top of the st. oblong-spatulate to 

 lanceolate, leathery, narrowed at base 

 and stalked, acute, spiny-toothed, l^ft. 

 or less long : fls. orange- or saffron-col- 

 ored, fragrant, in drooping racemes 4-10 

 in. long. Venezuela, Colombia. 

 B.M. 4922. B.R. 1764. Blooms 

 in June and July. 



spindsa, Mez (C. Riedelidna, 

 Regel). Plant 5-6 ft., glabrous, 

 stout and erect: Ivs. obovate- 

 lanceolate, sessile, 20 in. or less 

 long,,spinose-serrate :fls. orange- 

 yellow, in slender racemes 5-8 

 in. long. Brazil, 

 fulgens, Hook. f. Plant 3 ft. or more, very stout: 

 Ivs. spatulate-obcuneate, narrow, remotely toothed 

 near the apex, narrowed into a very short petiole, 

 very coriaceous, 1 ft. or so long: fls. deep red, with 

 yellow disk, handsome, in erect racemes 4 or 5 in. long. 

 S. Amer. B.M. 5626. 



C. latifdlia, Radlk. (Theophrastus latifolia, Willd.). Lvs. grace- 

 fully elliptic, petioled, narrowed at both ends, mucronate-serrate : 

 racemes erect. Colombia. T H B 



CLAYTONIA (after John Clayton, of Virginia, one of 

 the earliest American botanists upon whose collections 

 Gronovius based the Flora Virginica). Portulacdcex. 

 SPRING BEAUTY. Little smooth succulent herbs some- 

 times transferred to gardens for their bright flowers. 



Perennials with slender, 2-1 vd. sts. from a deep, 

 globular corm, and loose racemes of white or rose- 

 colored fls. with deeper veins, appearing among the 

 first wild fls. and lasting only a few days. The genus 

 is characterized by its oval, persistent sepals and 5 

 stamens. Plants can be secured from dealers in native 

 plants. They can be naturalized in moist places, and 

 do well in half -shady spots at the bottom of a rockery.

 Montia.
