SAGITTARIA 



SAIXTPAULIA

and lily-ponds. Tender to frost. It is sparingly 

 naturalized in the southern parts of the U. S., on both 

 the Atlantic and Pacific sides. 



AA. Sepals of pistillate fls. reflexed after flowering: 

 pedicels of these fls. slender: carpels somewhat 

 glandular. 

 B. Bracts at base of whorls united, as if only 1. 



subulata, Buch. (5. natans, in part. S. pusitta, 

 Nutt. . Slender and simple, 'usually only a few inches 

 high: Ivs. linear or narrowly oblanceolate, rigid: fls. 

 few, usually in 1 whorl, white, >-%in. across, the 

 filaments broad. N. Y. to Ala., along the coast. 

 Offered by dealers in native plants. A plant once sold as 

 S. natans is said to have come from the Amazon Valley; 

 from this the form known as "Xew Era" was derived; 

 and a cross of the latter with "5. lanceolata" (S. land- 

 folia?), native in La., gave the form "Francis M." S. 

 natans, Pallas, the accepted species under this name, 

 is native in X. Eu. and Siberia. 



BB. Bracts 3, at base of the whorls. 

 c. Lvs. usually distinctly sagittate. 



latifdlia, Willd. (S. varidbilis, Engelm.). Fig. 3519. 

 Very variable in stature and shape of Ivs., ranging from 

 a few inches to 3-4 ft. tall: Ivs. mostly broad-sagittate 

 with long basal lobes, but running into very narrow 

 forms: fls. clear white, about 1 in. across, usually 

 mono?cious. the filaments slender: achene winged, with 

 a lateral or oblique beak. Common everywhere in 

 margins of ponds and lakes, and offered by dealers in 

 native plants for colonizing in bog-gardens and in lily- 

 ponds. There is a double-fld. form known as S. vari- 

 dbilis fl.-pl., Hort., which probably belongs here. G. 

 29:31." 



sagittifdlia, Linn. OLD-WORLD ARROWHEAD. Rhi- 

 zome thick and tuberous, stolon-bearing: Ivs. broad and 

 sagittate, very variable in form and size: scapes erect, 

 simple or branched, overtopping the Ivs. : bracts narrow- 

 ovate, free or slightly connate at base, shorter than the 

 pedicels: petals large, white; filaments glabrous: achene 

 nearly or quite orbicular and in this respect differing 

 from the allied American species. Throughout Eu. and 

 Asia. By some authors the American S. lalifolia and 

 others are considered to be con-specific. Var. flfire- 

 pleno, Hort. (S. japonica, Hort. S. japonica fl.-pl., 

 Hort. i. is a form with double fls. common in cult. G.C. 

 111.30:171. Gn. 74. p. 67. G.M. 44:779. G.W. 3, 

 p. 621. J.H. III. 43:219. S. chinensis of most trade- 

 lists is apparently one of the many forms of this spe- 

 cies. There appears to be another S. chinensis in the 

 trade, with lanceolate Ivs., the botanical position of 

 which is undetermined. 



cc. Li-s. usually oblong or linear and not sagittate. 

 D. Filaments slender, tapering upward, cobwebby. 



lancif olia, Linn. Erect and somewhat rigid, glabrous, 

 the scape sometimes reaching 5 ft.: Ivs. lanceolate to 

 narrow-oblong to nearly linear, nerved from the thick 

 midrib: fls. white, in several whorls. Swamps, Del. to 

 the tropics. 



DD. Filaments abruptly broadened, pubescent. 



graminea, Michx. Erect and simple, glabrous, 2 ft. 

 or less high: Ivs. reduced to phyllodia, flat, broad-linear 

 to lance-elliptic, pointed: fls. small, white, in 2 or 3 

 whorls. Newfoundland to Gulf . 



S. macTOphylla has appeared in trade-lists as "a variety with large 

 foliage and tall lax spikes of white fls." Its botanical position is 

 uncertain as there are two distinct things of this name, one a valid 

 species, the other a large-lvd. form of S. sagittifolia. 



F. TRACT HuBBARD.f 



SAGUERUS (East Indian name). Palmacese. An 

 older name for Arenga, but discarded by the "nomina 

 rejicienda" of the Vienna rules. Arenga mindorensis, 

 Becc. (Saffuerus mindorensis, O. F. Coot), has recently 



been intro. by the U. S. Dept. Agric. from the Philip- 

 pines. It is described as a palm 5-10 ft. high, and proba- 

 bly of decided ornamental value for greenhouses and 

 probably also in S. Calif, and S. Fla. Yet little known 

 in this country. 



SAGUS RUFFIA: Raphia. 



ST. JOHN'S-WORT: Hyperieum. 



SAOTTPAULIA (from the discoverer of the plant, 

 Baron Walter von Saint Paul). Gesneriaceie. Hairy 

 often stemless perennial herbs, used for greenhouse 

 flowering, the blossoms providing an attractive blue.

3520. Saintpaulia ionantha. A young plant 

 just coming into bloom. ( X H) 



Leaves long-petioled, ovate: peduncles radical (or 

 axillary in the caulescent species), 1-5 in. high, bearing 

 several (or 1) fls. in a loose cyme: calyx small, deeply 

 5-lobed; corolla wide-campanulate, tube short, the 

 lobes elliptic, blue; perfect stamens 2; ovary hairy: 

 caps, oblong, loculicidally 2-valved; seeds small, 

 ellipsoid. Four species, Trop. Afr. 



The end of March is a good time to propagate saint- 

 paulias, when the ripened leaves should be cut off with 

 about an inch of the stalk attached, and inserted in the 

 sand-bed, covering only a small part of the leaf-blade. 

 The sand should not be kept too wet during the process 

 of rooting. Their propagation from seed and general 

 culture is similar to that of gloxinia. The plants may 

 be flowered the entire year or given a period of rest by 

 partly withholding water. (G. W. Oliver.) 



ionantha, Wendl. AFRICAN VIOLET. L'SAMBARA 

 VIOLET. Fig. 3520. Stemless, hairy: Ivs. many, 1H 

 in. long, ovate or subcordate, thin, regularly crenate, 

 clad on both surfaces with many short and a few very 

 long white hairs: peduncles 14 in. long, 1-6-fld.: 

 calyx-lobes linear; corolla-lobes not very equal: caps, 

 narrow-oblong. Trop. Afr. Gt. 42:1391 and p. 323. 

 Gn. 47:133; 74. p. 103; 79, p. 13. G.M. 37:62; 55:97. 

 G.C. 111.13:685. Gn.W. 25:345. G.W. 10, p. 343. 

 R.H. 1893, p. 321. Var. grandifldra, Hort., has much 

 larger fls. than the type, the fls. intense violet. Var. 

 variegata, Hort., has the Ivs. variegated with light 

 yellow turning to white. 



kewensis, C. B. Clarke. Lvs. entire, with numerous 

 long white hairs: calyx-lobes oblong-linear : caps. 2 or 3 

 times as broad as the preceding and more shaggy, 

 white-hairy. Trop. Afr. B.M. 7408. R.B. 20:109 (both 

 as S. ionantha). Very closely related to S. ionantha 

 and confused with it. 



S. pusilla, Engler, and S. Goetzeana, Engler, of German East 

 Africa, appear not to be in cult. p TRACT HlJBBARD.
