The following American trade names can not be satisfactorily 

 accounted for as species: S. acaidig is said to be one of the most 

 important commercial species cult, in Amer. S. circinata is cult, 

 at Harvard Botanic Garden. S. Lageriana was intro. from Colom- 

 bia and probably belongs to species already described from that 

 country. It is said to be a very light green plant and a strong grower, 

 whereas S. Pitcheriana is of dwarfer habit and with sts. and under 

 surface of fronds red and upper surface dark green. S. Mandiana 

 is a recent intro. by W. A. Manda which can not be satisfactorily 

 placed. 5. paradoxa. Offered by John Saul, 1893. S. Pitche- 

 riana. Consult S. Lageriana. Colombia. S. rubicunda and S. 

 triangulari* were offered by Saul in 1893. S. umbrfoa. Once cult, 

 by Pitcher & Manda, of the United States Nurseries.

R. C. BEXEDICT.t 



SELENIA (probably from the Greek moon; said to 

 refer to the round seeds). Cruciferae. Small annual 

 herbs sparingly grown in gardens: Ivs. pinnatisect: 

 racemes terminal, leafy: fls. yellow; sepals spreading, 



colored, subequal; petals erect: silique stipitate, oval 

 berry much compressed or turgid, acute at the base, 

 valves reticulate. Three species, N. Amer. 



aurea, Xutt., is a hardy annual of the mustard 

 family, a native of the U. S. from Ark. and Texas to 

 the base of the Rockies. It is not known to be cult, in 

 Amer., but it seems to be one of the prettiest of our few 

 native ornamental crucifers. It has small yellow fls. 

 about }/$&.. across, each of the 4 petals having a central 

 band of red. It is also interesting for its finely cut foli- 

 age and its flat pods through which the seeds may be 

 vaguely seen, as in the case of lunaria, or "honesty." 

 It grows about 9 in. high. B.M. 6607. 



F. TRACT 



SELENICEREUS (moon goddess and cereus). Coctd- 

 ceae. Cacti with slender trailing hanging or climbing 

 sts., more or less epiphytic: ribs several, usually low, 

 with closely set areoles bearing small short or acicular 

 spines: fls. large, nocturnal, fragrant; ovary and fr. 

 covered with clusters of small spines often accompanied 

 by long hairs. More than 20 species are known. This 

 genus contains a number of easily grown species which 

 are great favorities in cult, on account of the great size 

 and beauty of the fls. Some of the species are reported 

 to possess medicinal properties. These plants have been 

 referred to Cereus. 



A. Fl.-tube and ovary without long hairs. 

 B. Spines on sts. acicular. 



vagans, Brit. & Rose (Cereus vagans, Brandeg.). Sts. 

 slender, numerous, clambering over rocks in the wild 

 state, but in cult, ascending: ribs low: spines rather 

 short, yellowish: fls. 6 in. long; tube, including throat, 

 about 4 in. long, slightly curved, brownish, with small 

 scattered bracts bearing in their axils clusters of 5-8 

 acicular spines; throat narrow, 2 in. long; sepals linear, 

 the outer ones brownish, the inner ones greenish white, 

 2>i in. long; petals white, oblanceolate, 2K in. long 

 with a short acuminate tip, the margins, especially 

 above, undulate or toothed; ovary covered with acicu- 

 lar spines. West coast of Mex. 



BB. Spines on sts. not acicular. 



spinuldsus, Brit. & Rose (Cereus spinulosus, DC.). 

 Slender climbing vine, 10-14 ft. long: ribs usually 5, 

 not very conspicuous in age: spines about 8, very short, 

 usually dark: fls. 4J^-5 in. long, white, with a pink 

 tinge; ovary and fl.-tube bearing small clusters of 

 acicular spines but no long hairs. Common in N. E. 

 Mex. and S. E. Texas, but not found in the W. 

 Indies. Bliihenden Kakteen, pi. 53. 



AA. Fl.-tube and ovary bearing long hairs among the spines. 



B. Spines of the sts. acicular. 



c. Color of spines white. 



Donkelseri, Brit. & Rose (Cereus Donkdsri, Salm- 

 Dyck). A slender epiphytic plant, much branched, 

 clinging to the bark of trees by aerial roots, commonly in 

 company with orchids: branches long, slender, nearly 

 terete, about 5^in. diam. with 6-8 low, almost incon- 

 spicuous ribs; spines 10-15, very short, snow-white, 

 closely appressed to the st. Brazil. 



cc. Color of spines brownish. 



grandifldrus, Brit. & Rose (Cereus grandiflorus, Mill.). 

 Creeping or clambering vines: sts. stout, often 1 in. 

 diam., bluish green: ribs 7 or 8, low: spines acicular, 

 yellowish brown or brownish: fls. very large, fragrant, 

 6-8 in. long. Jamaica, but said also to be native of 

 Mex., which is doubtless wrong. B.M. 3381. A num- 

 ber of species resembling S. grandiflorus in a general 

 way, but specifically distinct, are often to be found 

 under this name in collections; they need further 

 study. This species is used in the manufacture of a 

 heart-tonic.
