426 ROSACEiE. Waldstkima. 



9. WALDSTEINIA. Willd.nct. nat. cur. Berol. 2. ;;. 103; Tratt. Eos. 



Waldsteinia & Comaropsis, DC. (excl. spec.) 



Tube of the calyx turbinate or obconic ; the limb 5-cleft, with 5 alternate 

 sometimes minute and deciduous bracteoles, which are occasionally wanting. 

 Petals 5, sessile, decidtious. Stamens numerous, inserted into the throat of the 

 calyx above the glandular and somewhat crenated border of the disk which 

 lines the calyx-tube : filaments filiform, rather persistent. Achenia few 

 (2-6), dry or somewhat fleshy, minutely pubescent or hairy, inserted on a 

 short (glabrous or villous) rece])tacle : styles terminal, filiform, deciduous 

 frona the carpel by an articulation : stigma simple. Seed erect. Radicle 

 inferior. — Low perennial herbs, with a prostrate or creeping rhizoma, and 

 mostly radical roundish 3-5-lobed or divided leaves. Scapes bracteate, 

 several-flowered. Petals yellow. 



The calyx of Dalibarda fragarioides, Michx., is (perhaps always) bracteolate ; 

 but the bracteoles are minute and deciduous. Tliis plant, and the nearly allied 

 Siberian species (which we have only seen in the Royal Herbarium at Berlin), 

 with D. lobata, Ell., do not differ from Waldsteinia gcoides of Hungary in any im- 

 portant character, except that tlie receptacle is villous in the former, and glabrous 

 in the latter species, wliich also has a somewhat leafy scape. The genus Co- 

 maropsis, therefore, will form at most only a section of Waldsteinia. 



1. W. fragarioides (Tratt. 1. c.) : somewhat hairy ; rhizoma rather thick ; 

 leaves trifoliolate, with the leaflets broadly cuneiform and petiolulate (or 

 rarely somewhat united), crenate-toothed and incised ; scapes erect, bracte- 

 ate, several-flowered ; segments of the calyx shorter than iheobovate petals ; 

 carpels 4-6, minutely hairy. — Dalibarda fragarioides, Michx. ! fl. 2. p. 300, 

 t. 28 ; Pursh, fl. 1. p. 3.51 ; Bof. mag. t. 1567 ; Ton: ! fl. 1. jy. 491. Co- 

 maropsis fragarioides, DC! inodr. 2. p. bob; Hook.! fl. Bor.-Am. 1. p. 

 177. C. Doniana, DC. I. c. 



Shady woods and hill-sides, Canada ! and Northern States ! and on the 

 Alleghany Mountains to Georgia (ex Elliott). May-June. — Leaves and 

 scapes 4-8 inches high. Leaflets rarely 5. Bracts rather small, foliaceous. 

 The C. Doniana is certainly only a state of this plant with smaller petals. 

 — Barren Straxchemj. 



2. W. lobata : hirsute ; stems somewhat flagelliform ; leaves nearl}^ orbi- 

 cular, cordate with a narrow sinus, incisely crenate, mostly 3-5-lobed ; scapes 

 filiform, ascending, somewhat cymosely 4-8-flowered, bracteate ; tube of the 

 calyx narrow ; the segments rather longer than the oval petals ; carpels 

 mostly 2, canescent. — Dalibarda lobata, Baldw. ! in Ell. sk. 1. ji. 571; 

 Hook. ! ic. pi. t. IQ. 



Hills near Flint River, Georgia, Baldwin ! Near Augusta, Dr. Wray ! and 

 near Columbus in the same State, Dr. Boijkin ! April-June. — Rhizoma 

 slender. Leaves and scapes 4-8 inches high. Leaves hirsute on the veins, 

 clothed with a soft pubescence beneath. Bracts small, foUaceous. 



Subtribe 2. Cercocarpej';. — Calyx tubular, sometimes imbricate in 

 aestivation. Stamens numerous. Carpel solitary, dry: style terminal. 

 Seed erect. Radicle inferior. — Shrubs or small trees. Flowers perfect.
