NYMPH^A 



88. Capensis X Zanzibariensis. Lvs. somewhat pel- 

 tare, orbicular-ovate, strongly sinuate, angle of lobes 

 acuminate; under surface dark purple: 8-16 in. across. 

 Us. rich blue, open 3-5 days, from 9 A. M. to 4 or 5 p. M., 

 6-8 in. across: sepals green outside, blue within; petals 

 15-20, narrow, acute: stamens 60-100: appendage blue. 



Cult, about Phila. Free bloomer, strong grower. 



89, Zanzibariensis, Gasp. Lvs. somewhat peltate, or- 

 bicular or orbicular-ovate, margin closely sinuate-den- 

 tate; angle of lobes hardly pointed, under surface more 

 or less suffused violet; diam. 8-15 in. : Us. 6-12 in. across, 

 open three to five days from 11 A. M. to 5 P. M. ; sepals 

 green outside, margins purple, deep purplish blue 

 within; petals 18-24, oblong, obtuse, deep blue; sta- 

 mens 136-242, appendage dark blue; back of anther 

 dark crimson-violet; outer filaments obovate, yellow. 

 Zanzibar, B.M. 6843 (as N. stellata, var. Zanzibarien- 

 sis).. On. 25:431 (small). 90. Var. azurea, light blue, 

 and 91, var. rosea, pink, are otherwise like the type, 

 but open earlier in the morning; they come up pro- 

 miscuously from seed of the type or of one another. 



92. Astraea, Grey (N. gracilis xN. ZanzlbarUnsis}. 

 Leaves floating, with general habit of a strong-growing 

 N. gracilis, green, tinged purple beneath. Fls. stand- 

 ing well above water, stellate, with a resemblance to 2V. 

 gracilis, but much larger; sepals green, shading to yel- 

 low at base, the inner surface bright blue, shading 

 through white to translucent at the base; petals blue, 

 shading to white at base, usually about 17 in number; 

 stamens less than 70, linear-lanceolate, yellow, tipped 

 with blue-purple; stigma less than 20-celled, with blunt- 

 toothed, yellow apices. Both parents hybridize freely 

 either way, but the hybrid is sterile. Unites the Ameri- 

 can (Mexican) with the African species. Var. rdsea, 

 Grey, is like the preceding, but the color is rose-pink 

 instead of blue; it is hybridized with 2V. Zanzibarien- 

 sis rosea instead of the type. 



SUBGENUS VI. ANECPHYA. 



93. gigantea, Hook. Lvs. narrowly peltate, elliptic or 

 ovate, margin sinuate-dentate, sinus open; under sur- 

 face brownish pink, becoming purple; 18 in. across: fls. 

 light blue to violet (rarely rose color or white), open 

 seven days from 9 A. M. to 6 p. M. ; diam. 6-12 in. ; se- 

 pals pure green; petals very many, dark blue at tip, 

 shading to nearly white at base; stamens 680-745; 

 filaments mostly filiform ; anthers bright yellow. 

 Australia. B.M. 4647. F.S. 7:751. The most delicate 

 and lovely, and withal one of the largest of the genus.

 GUM. Tupelos are bold and picturesque, hardy decidu- 

 ous trees, valued for the flaming scarlet of their autumn 

 foliage and for the distinctness of their winter aspect. 

 They grow in swamps and are usually 40-60 feet high, 

 attaining a maximum of 100 feet. Old specimens 

 often have a melancholy appearance by reason of the 

 drooping habit of the lower limbs. The upper branches 

 of a Tupelo are often twiggy, crooked or "kinky." The 

 foliage is leathery, and as glossy as if varnished.

Tupelos are hard to transplant from the wild, even 

 when heavily pruned, because they have remarkably 

 long roots with few rootlets. Nursery-grown trees that 

 have been frequently transplanted are preferable, but 

 seedlings are easily raised. Of the 7 species, 2 are na- 

 tives of eastern Asia, the rest of North America. The 

 only species offered by American nurserymen is 2V.

Nyssas are trees or shrubs with petiolate, usually en-

heads. Unlike the Dogwoods (Cornus), they belong to 

 a group in which the fls. are unisexual, instead of her- 

 maphrodite. From Aucuba and Garry a they differ in 

 having alternate Ivs. Nyssa is distinguished from its 

 immediate allies by the following characters: petals 

 of the male fls. none, or 4 to many, imbricated; stamens 

 4 to many: ovary 1-celled; style 1, simple or 2-parted.
