460 ARUM FAMILY. 



4. RICHARDIA. (Named for the French botanist, L. C. Richard.) 

 The first species is referred by some recent writers to the genus ZAN- 



TEDESCHIA. 2/ 



R. Africana, Kunth. ^ETHIOPIAN or EGYPTIAN CALLA, CALLA LILY, 



of common house culture, but a native of the Cape of Good Hope and not 

 a true Calla. A familiar plant, with glossy-green, broadly sagittate 

 leaves and large, pure white spathes. There are dwarf varieties. 



R. 6/bo-maculata, Hook. f. SPOTTED CALLA. Leaves long-hastate, 

 cuspidate at the end, with oblong, white blotches ; spathe smaller than in 

 the last, greenish-white. Cape of Good Hope. 



R. hastata, Hook. f. YELLOW CALLA. Leaves soft, hastate- ovate, cus- 

 pidate, not spotted ; spathe greenish-yellow, with a long- cuspidate limb. 

 Cape of Good Hope. 



5. SYMFLOCARPTJS, SKUNK CABBAGE. (Greek for fruit grown 

 together.} 11 



S. fcetidus, Salisb. The only species, in swamps and wet woods, 

 mostly N. ; sending up, in earliest spring, its purple- tinged or striped 

 turtle-head-like spathe inclosing the head of flowers, and later the large 

 leaves, when full grown l-2 long, in a cabbage-like tuft; the fruit 

 2' -3' in diameter, the hard bullet-like seeds almost \' wide, ripe in 

 autumn. 



6. CALLA, WATER ARUM. (An ancient name.) Flowers early 

 summer. 2Z 



C. paliistris, Linn. Cold and wet bogs from Penn., N. ; a low and 

 small, rather handsome plant ; leaves 3'-4' long ; filaments slender ; 

 anthers 2-celled. 



7. ANTHURITTM. (Greek : tail flower, referring to the projecting 

 spadix.) Many species are cultivated in choice collections, but the fol- 

 lowing are probably the commonest, the two first being grown for the 

 gaudy spathes and spadices, and the two last chiefly for the fine foliage. 



* Leaves ovate-lanceolate or narrower. 



A. Scherzerianum, Schott. Leaves evergreen, oblong-lanceolate, deep, 

 rich green, spreading or recurved, tapering at the base, l-2 long, the 

 blade not oblique ; scapes slender and surpassing the leaves, bright 

 red ; spathe ovate-oblong, somewhat cordate, brilliant red (like the 

 spadix), 3'-4' long. There are many forms in cultivation, including one 

 or two with white spathes. Guatemala. 



A. Andrceanum, Linden. Leaves ovate-lanceolate, cordate at the base, 

 deep green, the blade oblique or hanging on the petiole ; scapes some- 

 what overtopping the leaves ; spathe broadly ovate and cordate, 6'-10' 

 long, wrinkled, orange-red ; the spadix yellowish. Colombia. 



* * Leaves ovate or broader. 



A. crystd/linum, Linden & Andre. Leaves broadly ovate and deeply 

 cordate, acuminate, bright velvety green, and the principal veins mar- 

 gined with crystal-white (violet color when young), the blade hanging or 

 oblique on the petiole ; spathe linear-oblong, acuminate, green. Peru.
