OSMI^NDA (from Osmunder, aname of a Saxon god). 

 itsmitnddceGe. A small genus of showy native ferns, 

 witli rather coarse foliage, but highly ornamental from 

 their clustered habit. The sporangia are formed in 

 panicles borne on the veins of reduced Ivs., provided 

 with a rudimentary transverse ring and opening verti- 

 cally. 



A. I/vs. fully bipinnate. 



reg&llB, Linn. Royal Fern. Growing in clumps 2-5 

 ft. hiji^h, some of the leaves bearing panicles at their 

 summits; pinnse 1-2 in. long, rounded at the base and 

 usually blunt. Well adapted for open, moist places. 



^>.: 



Eu., N. Amer. and Japan. — Commonly called Flowering 

 Fern or King-fern. O. Japonica, Thunb., is a form with 

 the sporophylls forming distinct leaves and soon with- 

 ering away ; various crested forms appear in cultivation. 

 AA. Li'S. bipinnafifid only. 

 cinnamdmea, Linn. Cin-xamon Fern. Fig. 1.596. 

 Plate XI. Growing in clusters 2-1 ft. high or even 

 more, the sporophylls appearing earliest, at first green. 



OSTROWSKIA 



but becoming pale, long and narrow, cinnamon-colored 

 at maturity of the spores, the Ivs. growing about a 

 crown from a large, mostly vertical rootstock. N. Amer. 

 — Very handsome for decorative purposes, especially for 

 low grounds. 



Claytouiina, Linn. Growing in crowns, with the 

 sporangia confined to a few (1-10) of the central pinnsB 

 of the leaf, and of a dark brown color. Similar to the 

 last, but lacking the little tuft of wool in the axils of 

 the pinniB which characterizes the Cinnamon Fern. N. 

 Amer; said also to grow in India. 



L. M. Undekwood. 



Osmundas are strong - growing ferns of vigorous 

 constitution, and well adapted for general culture in 

 any fertile soil which is not over dry. They are deep- 

 rooted ferns and, therefore, require considerable di-i.th 

 of soil. All the species do well in full sniilii;lit. 

 but the most satisfactory position for all the -.|„ ,ies 

 would be a deeply dug, thoroughly enriched border ly-

 though not in such wet positions as O. regalis. It 

 grows most luxuriantly in partial shade. In a wild state 

 it occasionally attains a height of 6 ft.

OSTEOMfiLES (Greek, stotie apple or stone fruit). 

 Ri'si'iccif. The plant which bears the uncomfortable 

 name of Osteumeles anthyUidifolia is a white-fld., red- 

 fruited bush, ranging from China through the Pacific 

 islands as far south as Pitcaim's island. It has pin- 

 nate foliage, silvery beneath, each leaf 2—1 in. long and 

 composed of about 25 lfts. The specific name of the 

 plant records its resemblance in foliage to Anthyllis 

 Barba-Jovis, a plant with pea-like fls., known as Ju- 

 piter's Beard, which is considerably used for seaside 

 planting in frostless countries. Botanically Osteomeles 

 is closest to our shad bush (Amelanchier), but inferior 

 in hardiness and in beauty of fls. All the other species 

 of Osteomeles (about 7) are natives of the Andes, and 

 have simple Ivs. The silvery nature of O. anthyllidi- 

 folin varies considerably in the wild, and glabrous speci- 

 mens have been collected. 



Generic eharacters: trees and shrubs: Ivs. alternate, 

 stalked, leathery, evergreen, entire or serrate: fls. 

 white, few or numerous, in flatfish clusters: calyx-tube 

 bell- or top-shaped, adnate to the carpels; lobes 5, per- 

 sistent; petals 5, oblong; stamens 10 or more, inserted 

 on the throat nf the calyx; carpels 5, more or less grown 

 together and to the calyx: drupes 5-stoned. 



anthyllidifdlia, Lindl. Evergreen bush, 5-6 ft. high, 

 much branched: bark brownish black: Ivs. spreading 

 and recurved; lfts. more or less in pairs, yellowish 

 green: fls. about % in. across, a dozen or so in a clus- 

 ter. B.M, 7331. -sv. M. 



OSTEOSPfiEMUM moniUienim is a shrubby yellow- 

 fl<l. eoHiptKsite, growing 2—1 ft. high, which was offered 

 in ISill by Reasoner Bros.. Oneco, Fla. It has dropped 

 out of cult. It is fully de.scribed in Flora Capensis 

 3:133, where the entire genus of 38 species is mono- 

 graphed. 



OSTEOWSKIA after N. ab Ostrowsky, Russian pa- 

 tron ' iiiipanulAceie. The Giant Bell- 

 plow i ■ ranks among the two dozen most 

 intere-i III,' naiii j.erennials " introduced during the 

 last tw<i deeailes c.t the nineteenth century. Each stem 

 grows 1 or 5 ft. high, is branched only at the top, and 

 bears 3-6 bell-shaped, pale lilac fls. 1-6 in. across and 

 1 in. deep. A healthy clump may throw up as many as 

 0-lOstems. Beforethediscovery of thisplant,P;a#ycodon 

 grandiflorum was generally considered the showiest of 

 all the large bell-flowers, but J. N. Gerard declares that 

 the Platycodon is very commonplace beside Ostrowskya. 

 In the colored plates the flowers have a rather washed- 

 out appearance, except in "Garden," which shows pink- 

 ish tints. Gerard describes the color as a very light 

 lavender or mauve, almost white, with deeper veinings.
