88. Capensis X ZanzibarUtisls. Lvs. somewhat pel- 

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

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

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

 0-8 in. across: sepals green outside, blue within; petals 

 1.5-20, nai-row, acute; stamens 60-100: appendage blue. 

 Cult, about Phila. Free bloomer, strong grower. 



89. Zanzibari^nsis, Casp. 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. 8-15in. : fls. 6-12 in. across, 

 open three to live days from 11 A. M. to 5 p. M. ; sepals

 Zanzibar, B.M. 6843 (as N. stellala, var. Zamibarien- 

 sis). Gn. 25:431 (small). 90. Var. azdrea, light blue, 

 and 91, var. rdsea, 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. Astraaa, Grey {N. qrncilis x IT. Zamihari(nsis). 

 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 N. 

 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 al)out 17 in iuiiuIht; 

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

 with blue-purple; stigma less than 20-cened. witli )ilunt- 

 toothed, yellow apices. Both parents bybridizi- frt-fly 

 either way, but the hybrid is sterile. Unites tiii' Anicri- 

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

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

 instead of blue; it is hybridized with If. Zanzibarien- 

 sis rosea instead of the type. 



Subgenus VI. Anecphya.

N'^SSA (name of a water nymph ; these trees grow 

 in swamps). Cornaceie. Tupelo. Pepperidge. Sour 

 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, tiie rest of North America. The 

 only species offered by American nurserymen is JV. 

 srjlvatica. 



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, in.stead of her- 

 maphrodite. From Aucuba and Garrya they differ in 

 having alternate lvs. 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.
