1602. Oxalis Orte: 



1. rdsea, Feuil. Stem elongated, erect: lvs. scattered, 

 rather sliort-petioled ; lfts. obcordate : fls. in open, 

 irregularly forked cymes on elongated axillary pedun- 

 cles, rather large, rosy, with deeper veins. Chile. B.M. 

 2830. B.E. 13:1123 (as 0. floribunda). O. Simsii, 



Sweet, scarcely differs, except in its darker red fls. 

 Chile. B.M. 2415 (as O. rosfi!). 



2. comiculfLta, Linn. Slender, prostrate, often root- 

 ing, loosely hairy: lfts. obcordate; fls. usually 2 to 3 

 together, small, yellow. — A tropical form of this poly- 

 morphous species is universal as a greenhouse weed, 

 especially iu Agave and Cactus tubs. 



V.ir. atropurpilrea. Planch. {O.tropceololdes, Schlach- 

 ter). .\s.-iiiiliiii,'. tufted, with deep purple-red stems 

 and fcliaiTf. 8"nu'tinies used for beds or borders, and

 K.ll. 1«)7, p. 499.

 stemmed: lvs. clustered, long-petioled; lfts. obcordate:

 low, with reddish veins. Chile.

 ratlier tli-Nh\- and usually reddish: lvs. scattered, often 

 on long, rolnifd prti<iles; lfts. red below, cuneate, with 

 liniad \'-sliaped notch at end: fls. very short-stalked, in 

 furk.-d ovnu's on elongated peduncles, small, yellow, 

 Willi deeper veins. Peru. Gt. 1875:817. 



5. delic&ta, Pohl. Stem erect, elongated, slender, 

 branching ; lfts. ovate or lance-ovate, acute : lis. in 

 forked cymes on elongated peduncles, small, pale rose.

6. Acetos6Ua, Linn. Wood Sokrel. Rhizome slender, 

 the ends scan-fly thickened, densely scaly: lfts. obcor- 

 date. unt orange-dutted: fls. solitary on the scapes, 

 white, with rosy veins. Eu., N. Araer. Gn. 47, p. 129.- 

 Wliile a charming plant for the wood-garden, this, which 

 is sometimes held to be the original Irish Shamrock, 

 scarcely enters into ordinary gardening. G.C. 11. 

 25:685." 



7. JapAnica, Pranch. & Sav. Lfts. broadly triangular. 

 scarcely notched, truncate. Otherwise similar to the 

 last. Japan. 



8. rilbra, St. Hil. Rhizome thickened at ends into 

 loosely toothed tubers, sometimes nearly an inch thick, 

 and often clustered: lfts. obcordate, more or less hairy,

 (Is. numerous, umltelled. rosy, with deeper veins. Bra- 

 zil. Gn. 50, p. 511 (as <>. florihiiiida). -VsuMly cult, as 

 O. floribunda, which name properly belongs to the 

 next, and sometimes, but also erroneously, as O. arbo- 

 rea. A lilac-flowered form passes erroneously for O. 

 lilac\na, &nA a white form for O. arborea, y&v.alba or 

 O. alhn : and O. violacea and O. violacea var. alba of 

 the trade seem to be this species and its variety. 



9. Martiina, Zucc. (O. tirbiea, St. Hil. O. bipunc- 

 tdta, Grah. O. floribunda, Lehm.). Bulbs composed of 

 numerous small ones: lfts. obcordate, somewhat hairy, 



with a marginal row and some scattered dots of 

 orange color beneath : umbels usually compound : 

 fls. rose-piurple. Trop. Amer. B.M. 2781; 3938. 

 — By a misprint this is sometimes advertised as 

 O. maritima.

 let. Eastern U. S. B. M. 2215. Mn. 5:121.-

 4, deltoid, truncately notched, each crossed by a pur- 

 plish band: fls. rather few, lilac to deep rosy. Mexico. 

 L.B.C. 8:790; 15:1500. G.M. 39, p. 403. Gn. 8, p. 43.- 

 Sometimes called O. esculenta, because of the large 

 fusiform roots beneath the bulbs. See Fig. 1601. 



12. lasiandra, Zucc. Lfts. 5 to 10, oblong-spatulate, 

 not notched, several inches long, radiately pendent 

 about a reddish disk at end of petiole: fls. crowded,
