NESTRONIA (according to the author, derived from 

 a Greek word for Daphne). Syn., Darbya. Santalaceae. 

 Native deciduous shrub closely related to Buckleya and 

 differing chiefly in its axillary fls., tufts of hairs at the 

 base of the stamens, simple stigma, and in its globose 

 fr. without enlarged persistent sepals. It has no par- 

 ticular ornamental qualities, but is botanically inter- 

 esting, as it is a parasitic shrub growing like buckleya 

 on the roots of trees, chiefly on those of pines and oaks. 

 For cult, see Buckleya. The only species is N. umbellula, 

 Raf. (Darbya umbellulata, Gray. Buckleya umbellu- 

 lata, Hieron.). Glabrous shrub, 1-3 ft., spreading by 

 suckers: Ivs. opposite, short-petioled, oval or ovate 

 to elliptic-oblong, acute or obtusish, usually narrowed at 

 the base, bright green, 1-2 3/ in. long: fls. 4-merous, 

 dioecious, apetalous, greenish white, small; the stam- 

 inate slender-pedicelled in 3-9-fld., peduncled umbels; 

 stamens 4, short; pistillate fls. solitary, on stalks 

 K-^in- long, with ovate calyx-lobes much shorter 

 than the tube: fr. globose, about ^in. across, purplish, 

 bloomy, crowned by the remnants of the calyx-limb. 

 May; fr. in June. Va. to Ga. and Ala. S.F. 7:75.

ovalifolia. (After No. 4.) The plant called Nym- 

 phsea ovalifolia, as intro. into gardens in 1916, is from 

 newly imported African seed, and was first raised by 

 E. T. Harvey, of Cincinnati. It is not the true N. ovali- 

 folia, Conard. The new plant has more oval Ivs. than 

 N. caerulea, and larger and paler fls. It is to be regarded 

 as a form of N. caerulea, deserving a personal name 

 rather than a Latin name. In 1908 Gilg of Berlin 

 described 6 new species of African water-lilies, all 

 allied to N. caerulea. The new form here mentioned 

 falls between N. magnifica and N. spectabilis of Gilg, 

 having certain characteristics of both species. The 

 plant is "a prodigious grower, the If.-stalks extending 10 

 or more ft." The fl. is "a rich cream color tipped with 

 blue at the end of the petals." (Quotations from letters 

 from Mr. Harvey.) Petals 20; stamens 92; carpels 21; 

 sepals thickly marked outside with black lines and dots. 

 Fl. 6-8 in. across. (Data from specimens furnished by 

 Mr. Harvey.) 



N. ovalifolia, Conard, Monogr. Nymph, 150, is from 

 German E. Afr., apparently not in cult. Lvs. narrowly 

 elliptic, with large irregular brown blotches above but 

 plain green beneath: fls. deep blue, closed in dull 

 weather. H. S. CONARD. 



PASANIA. Page 2479. 



The oldest and tenable name for this genus is Litho- 

 carpus, which is entered on page 3569. The species of 

 Pasania in the supplementary list of Quercus, page 

 2890, are also to go into Lithocarpus.

hastata, Cav. St. pubescent: Ivs. short-petioled, 

 orbicular to oblong, sometimes deltoid, sagittate or 

 hastate, dentate, somewhat tomentose beneath, pubes- 

 cent above; stipules filiform: pedicels axillary and 1-fld., 

 the involucel 5-bracted, the petals rose-colored and 

 veined at the base with purple. Brazil. Offered in 

 Calif., as a small purplish-fld. shrub.

acerifdlium, L'Her. One of the Pelargium section, 

 allied to No. 20, inserted here because Geranium a'tri- 

 odorum is a name in the trade and the G. citriodorum, 

 Cav., is considered to be referable to P. acerifolium: 

 the species P. acerifolium is shrubby or subshrubby, 

 3-4 ft. tall, glaucous-green, differing from P. angulosum 

 (of which Harvey makes it a variety) in having the 

 Ivs. more cuneate at base, more deeply lobed, and more 

 scabrous. S. Afr. Knuth, in his recent Monograph, 

 keeps the species distinct.
