F. TRACT HCBBARD.! 



SCKREBERA (perhaps after J. C. D. Schreber, 1739- 

 1810, physician and naturalist). Oleacese. Trees with 

 unequally pinnate Ivs. and fls. in very much-branched 

 cymes: calyx tubular-bell-shaped, irregularly 4-7- 

 lobed; corolla salver-shaped; tube cylindrical; lobes 4-7, 

 spreading; stamens 2, near the top of the corolla-tube; 

 ovary 2-celled. About 15 species, Afr. and India. 

 Xathusia, with 4 species at the date of Engler & Prantl, 

 Die Pflanzenfamilien, IV. 2 (1895), is a synonym of this 

 genus. 



swietenioides, Roxbg. (Nathiisia swietenioides, 

 Kuntze). A tree, about 40 ft. high, nearly glabrous: 

 Ifts. 5-7. ovate, acute, 4 x 2 in.: fls. white, with brown 

 marks, about ! >in. across, in many-fld. cymes. Cult, 

 in S. Fla. 



SCHUBERTIA (named after Gotthilf Heinrich yon 

 Schubert). Asdepiadacese. Twining shrubs, occasion- 

 ally grown in the warmhouse : Ivs. large: fls. large, white, 

 borne in loose umbels; sepals ovate, generally acute, 

 alternating with single glands; corolla funnelform or 

 salver-shaped, with a broad tube; crown upright, 

 included: follicles thick and hairy. About 6 species 

 from S. Amer. S. grandifldra, Mart. & Zucc. Fig. 3572. 

 Branches twisting, straw-colored, covered with long 

 rigid red-brown hairs: Ivs. cordate, obovate, acute, both 

 surfaces densely brown-pubescent: umbels few-fld.; 

 pedicels long-hairy: fls. white; sepals oval-acute; corolla 

 large, tube gourd-shaped, glabrous inside, the lobes 

 oval-elongate, obtuse, erect, sparsely pale yellow pilose 

 Brazil. G. 36:503; 37:351. Gt. 50:1492. G.F. 3:369 

 (adapted in Fig. 3572). Gn. 32:84. S. graveolens, 

 Lindl. (Araujia graveolens, Mast.), is a Brazilian 

 climber, likely to be found in collections of greenhouse 

 plants, smaller-fid, than the above. See p. 2610, under 

 Physianthus. There may be confusion hi the use of 

 the names S. graveolens, S. grandifiora, and Physianthus 



auricomus. 



SCIADOCALYX : Isoloma. The following species was 

 not treated under Isoloma, see Vol. Ill, p. 1705. 

 Isoldma Warszewiczii, Hort. (Sciadocalyx Warsze- 

 wiczii, Regel. Kohleria Warszewiczii, Hanst.). Perennial 

 herb, 3-4 ft. high, with catkin-like stolons: st., petioles, 

 lvs. ; and calyx villous-hirsute: Ivs. opposite, long- 

 petioled, oval or cordate, crenate: fls. hi axillary 

 umbels of 3-6 fls., bright yellow or yellowish green, red- 

 or brown-dotted; calyx adnate to ovary, 5-lobed, lobes 

 almost horizontally spreading; corolla almost oblique at 

 base, tube slightly inflected, limb 5-lobed, lobes rounded;

 Colombia. B.M. 4843. Gt. 2:256. 



SCIADOPHYLLUM (shade leaf, because of the 

 umbrageous foliage). Araliacex. As understood by 

 Bentham & Hooker in Genera Plantarum, it is a genus of 

 the American tropics, at that tune with about 22 known 

 species, differing from Schefflera, among other things, 

 in the calyptrate or coherent rather than free petals and 

 sometimes 4-merous fls. Harms, in Engler & Prantl's 

 Pflanzenfamilien, refers it to Schefflera, and under this 

 name (p. 3108) are here described any species probably 

 now in the trade. 



SCIADOPITYS (Greek, skias, skiados, umbrella, and 

 pitys, spruce, alluding to the position of the leaves). 

 Pinaceae. UMBRELLA PINE. Ornamental tree grown for 

 its handsome foliage and regular pyramidal habit. 



Evergreen resinous tree : Ivs. of two kinds ; small and 

 scale-like Ivs. scattered on the shoot, but crowded at 

 its end and bearing in their axils a whorl of 20-30 long 

 linear flat Ivs. furrowed on each side, more deeply 

 beneath; these Ivs. really consist each of 2 connate 

 Ivs. borne on undeveloped spurs like those of Pinus; 

 they have been sometimes called cladodes, but are not 

 true cladpdes: fls. mono?cious; 

 the staminate oval, consisting 

 of spirally disposed 2-celled 

 anthers and appearing in dense 

 clusters at the ends of the 

 shoots; the pistillate are soli- 

 tary at the ends of the shoots 

 and consist of numerous spirally 

 arranged scales subtended by a 

 small bract and bearing 7-9 

 ovules: cone oblong - ovate, 

 woody, the bracts connate, with the broadly orbicular 

 thick scales spreading at the margin; seeds oval, com- 

 pressed, with narrow wing, emarginate at the apex. 

 One species in Japan, with very strong and straight- 

 grained, nearly white wood. 



The umbrella pine is a very handsome tree of narrow 



3573. Whorls of foliage 

 of Sciadopitys verticillata.
