 Japanese botanist. Fl. summer. 2/ 



A. dec&ndra. Rich woods along the Alleghanios from Virginia S. : a tall, 

 ratlier pubescent herb, 3°- 5° high, imitating Spiraja Aruncus (p. 121) in ap- 

 pearance, but coarser ; leaflets of the decompound leaves mostly heart-shaped, 

 ciit toothed (2' -4' long) ; flowers greenish-white, with inconspicuous petals. 



A. Jap6llica, or Hoteia Japonica. Cult, from Japan for ornament : 

 only 1° - 2* high, witli leaflets of the thrice- ternate leaves lance-ovate or oblong, 

 and crowded white flowers of considerable beauty. 



12. TIARELLA, FALSE MITREWORT. (Diminutive of tiara, a tur- 

 ban ; name not very appropriate.)' y. 



T. Cordif61ia, our only species, in rocky woods, especially N/ .■ a low and 

 hairy herb, spreading by summer leafy i-unners ; leaves rouncfed heart-shaped, 

 sharply lobcd and toothed ; flowers in a short raceme on a leafless scape, Wight 

 white, in spring. 



13. MITELLA, MITREWORT, BISHOP'S-CAP. (Name means a lit- 

 tle mitre, from the shape of the 2-cleft ovary and young pod. ) Delicate plfints 

 of moist woods, especially N., spreading by summer leafy i-unners or joot- 

 stocks : fl. late spring and early summer, y, 



M. diph^Ua, Common or Two-leaved M. Hairy, with rounded heart- 

 shaped and somewhat 3 - 5-lobed rootleaves on slender petioles, and a pair of 

 opposite nearly sessile leaves on tliq scape below the slender raceme of many 

 white flowers. 



M. ntlda, Naked-stalked M. Mossy woods N. : a delicate little plant, 

 with roundish kidney-shaped doubly crenate leaves, and leafless scape (4' - 6' 

 high) bearing a few greenish blossoms. 



14. CHRYSOSPLENIUM, GOLDEN SAXIFRAGE. (Name in 

 Greek means jo/rfen sp/ccn. ) Fl. spring, y. 



C. AmfirinAniim; our only species, in springs or shady wet places N. : 

 alo-\y.and delicate smooth herb, with spreading repeatedly forked stems, tender 

 succulent small leaves, which are roundish, obscurely crenate-lobed, and mainly 

 opposite ; the inconspicuous greenish flowers nearly sessile in the forks. 



41. CRASSULACEJE, ORPINE FAMILY. 



Succulent plants, differing from the Saxifrage Family mainly in 

 the complete symmetry of the flovifers, tlie sepals, petals, stamens, 

 and pistils equal in number, or the stamens of just double the num- 

 ber ; the pistils all separate and forming as many (mostly many- 

 seeded) little pods, except in Penthorum, where they are united 

 together. (Lessons, p. 86, fig. 168- 171.) Penthorum, which is 

 not succulent, is just intermediate between this family and the fore- 

 going. Several are monopetalous, i. e. have their petals united 

 below into a cup or tube. 



§ 1. Leaves not at all fleshy, but thin and memhranacemis : the B cmariea united into 

 one 5-homed i-celled pod: no scales behind the maries. 



1. PENTHORUM. Sepals 5. Petals 5, small, or usually none. Stamens 10. 



Pod opening by the falling away of the-5 beaks, many-seeded. Earely.the 

 parts are in sixes or sevens. 



§ 2. Leaves thickened aTid succulent : qvaries separate, a minute scale behind each. 

 * Petals separate : sepals nearly so or united at the base, 



2. SEJIPERVIVUM. Sepals, narrow petals, and pistils 6-12 or even more, and 



stamens twice as many. Plants usually multiplying by leafv offsets, on 

 which the leaves are crowded in close tufts like rosettes.
