GETITSLLIS (old Greek name, of no particular 

 application). Amaryliidaces. Nine or 10 stemless 

 herbs, with the look of crocus, allied to Sternbergia, 

 from the Cape region, seldom cult, under glass; appar- 

 ently not in the trade: Ivs. usually appearing after the 

 fls., hnear, sometimes filiform and twisted: fls. appear- 

 ing through the ground, of delicate texture and of 

 short duration, fragrant, whitish, salverform, with a 

 long slender tube and 6 similar acute spreading segms.; 

 stamens 6 or more, attached in the throat; ovary 3- 

 celled, concealed in the bulb-neck: bulbous. Prop, by 

 offsets or seeds. G. dfra, Linn. Bulb lJ^-2 in. diarn.: 

 Ivs. 12-20, linear and twisted: fl. with whitish hmb 2 in. 

 or less long and tube 3-4 in. long; stamens 9-12: fr. 

 yeUowish, clavate, recorded as edible. B.R. 1016. 

 G. spiralis, Linn. Bulb 1-134 ™- diam.: Ivs. 4-6, linear- 

 subulate, very much twisted, 4-6 in. long; perianth- 

 tube 2-3 in. long, limb 1-1)^ in. long, whitish and 

 tinted red on the outside; stamens 6: fr. clavate, 2-3 

 in. long. B.M. 1088. G. ciliaris, Linn. Bulb 1}^ in.

diam.: Ivs. 20 or more, linear, twisted, prominently 

 ciliate: perianth-tube 2-3 in. long, the whitish hmb 

 J^in. long: fr. yellow, clavate, 2-3 in. long.

GEUM (probably originaUy from Greek, getw, to have 

 a taste; referring to the roots). Rosacese. Hardy border 

 and rock plants, some of which are valued for their 

 bright red flowers, some for their pure yellow flowers, 

 others for their long plumy fruits. 



Herbs, with a perennial rhizome, sometimes stolonif- 

 erous: root-lvs. crowded, odd-pinnate, the alternate 

 lobes often smaller, terminal ones largest; st.-lvs. few, 

 mostly of 3 Ifts. or bract-like: fls. 1-2 in. across, soli- 

 tary or corymbose or cymose; calyx persistent, its 

 tube nearly hemispheric, usually 5-lobed; petals 5, 

 nearly or quite round, longer than the calyx: fr. 

 bunched on a short receptacle, frequently plumed. — 

 More than 50 species, mostly in temperate and frigid 

 regions. 



The plumy kinds are aU contained in the subgenus 

 Sieversia. G. chiloense is the best species, and in the 

 gardens is commonly seen in double forms. A gar- 

 dener writes that "inferior forms show scarcely any 

 duplicity." Geums are of easy culture, and are propa- 

 gated by division or seed. It is said that they hybridize 

 freely if grown together. The dwarf kinds are suited 

 only to the rockery. Correvon, of Geneva, Switzerland, 

 writes that G. reptans is one of the best of the rockery 

 kinds, and needs fuU sunhght. For G. triflorum he 

 advises half exposure to sun and a hght, moist soil. G. 

 rivale grows naturally in marshy places. 



A. Plumy geums: style in fr. long and plumase 



B. Fls. yellow. 



c. Plants spreading by runners. 



reptans, Linn. Root-lvs. interruptedly pinnatifid; 



upper Ivs. 3-lobed, deeply crenate-serrate : fls. erect; 



petals obcordate, not much longer than the sepals. 



Eu. Gn. 45:284. — The purple styles are pretty. 



cc. Plants ?iot spreading by runners. 

 D. Root-lvs. pinnatifid. 

 montanum, Linn. An erect and single-fld. perennial 

 with lower Ivs. IjTate pinnatifid; terminal 1ft. broadly 

 ovate-rounded: calyx-lobes entire, while those of G. 

 reptans are often 3-cut at apex; petals 1-2 times the 

 length of the sepals. S. Eu. G.C. H. 13:425. Gn. 4.5, 

 p. 285. — Under the name of G. Heldreichii and G. 

 Heldreichii superhum are advertised what appear to be 

 forms of this with orange-colored fls. which often pro- 

 duce more than 1 fl. The name Heldreichii is of no 

 botanical significance. G.M. 46:371. 



DD. Root-lvs. kidney-shaped. 

 radiatum, Michx. (Sieversia Peckii, Rydb.) Very 

 hirsute: root-lvs. 2-5 in. broad: st. 1-8-fld.: bractleta 

 minute. Mountains of N. C. and Tenn. 



BB. Fls. bright red, unmixed inth yellow. 

 C. Lateral lobes oj Ivs. minute. 

 coccineum, Sibth. & Smith, not Hort. "St.-lvs. 3- 

 lobed; root-lvs. lyrate, the terminal lobe largest, cor- 

 date-reniform : fls. erect. Mt. Olympus in Bithynia." 

 The above is an exact translation of the entire descrip- 

 tion given by Sibthorp and Smith, Flora Grceca, t. 

 485. — The chances are that all the plants in the trade 

 under this name are really G. chiloense. The true G. 

 coccineum is known in the botanic gardens. 



cc. Lateral lobes of Ivs. 1 in. long. 

 chiloense, Balb. (G. coccineum, Hort., not Balb.). 

 "St.-lvs. 3-parted, laciniate; root-lvs. interruptedly 

 lyrate, pilose: terminal lobe rotund, somewhat 3-lobed, 

 crenate: fls. panicled: carpels villous." The above is a 

 hteral translation of B. R. 1348, where the terminal 

 lobe is shown to be 2J^ in. each way. Chile. B.R.
