NOLINA (after P. C. Nolin, joint author of an essay 

 on agriculture, Paris, 1755). JAlidcece. Syn., Beaiicar- 

 nea. Nolinas belong to the remarkable group of desert 

 succulents in the lily family known as the Dracffina tribe, 

 of which the Yucca is the best known example in our 

 gardens. Nolina recurvata, which is perhaps the most 

 desirable species, has a striking appearance. It has a 

 fleshy trunk 5-6 ft. high, surmounted by a crown of 100 

 or more leaves, which are long, linear and gracefully 

 recurved. The base of the trunk is swelled into a sort 

 of tuber a foot or more thick, which sits on the ground 

 like a huge onion. It has numerous very small, green- 

 ish white, 6-lobed fls., borne in panicles on flower- 

 stalks several feet high. Nolinas are essentially Mexican 

 plants. They are cult, in S. Calif., requiring similar 

 treatment to Agave, Dasylirion and Yucca, but Ernest 

 Braunton writes that they are not popular. In the East 

 a few kinds are offered. They are desirable plants for 

 fanciers who can house a collection of succulents. 



Nolinas are nearest to Dasylirion, but their Ivs. are 

 unarined, while those of the latter usually have hooked 

 spines. Fls. polygamo-dioecious, the loose racemes form- 

 ing a simple or compound panicle. Their stamens are 

 included, while those of Dasylirion are esserted. For 

 differences in fruit characters, see Dasylirion. The 

 species of Nolina are imperfectly understood. In addi- 

 tion to those given below, iV. Beldingi is offered. This 



was lately discovered in lower Calif, by T. S. Brandegee 

 on mountains above Cape St. Lucas. It is arborescent 

 and similar in habit to JV. longifolia, but with glaucous 

 Ivs. (see note below). Beaucarnea glauca of the trade 

 doubtless belongs in Nolina. Franceschi says it has 

 a crown of stift' glaucous Ivs. on a slender trunk with 

 a bottle-shaped base. 



A. Li^s. 8-15 lines wide. 

 B. Habit of foliage recurved, 

 c. Trunk scarcely bulged at the base. 

 longifdlia, Hemsl. {Dasylirion longifdlium, Zucc. 

 Beaucarnea longifdlia, B&ker). Trunk in cult. 4-6 ft. 

 high, 6 in. thick below the crown of Ivs.: Ivs. 

 100-200, green, 4-6 ft. long, 9-15 lines wide, per- 

 ceptibly narrowed from middle to apex. A glau- 

 cous form has been cult. G.C. II. 7:493, 567; III. 

 16:67. R.H._1876, p. 454. 

 CO. Trunk with a bulge at the base a foot or 



more thick. 

 recurvata, Hemsl. (Beaucarnea recurvitta, 

 Lem.l. Trunk in cult. 5-6 ft. high, 

 2-3 in. thick below the crown of Ivs.; 

 Ivs. green, equally wide all the way, 

 8-9 lines wide at base. G. P. 9:95. G. 

 C. 1870:1445. F.S. 18, p. 26. l.H. 8, 

 Misc. p. 59. — Var. intermedia, Hort., 

 has Ivs. which are less recurved and 

 shorter. Var. rtibra, Hort., has the 

 Ivs. tinged red near the liase. No 

 varieties, however, are advertised. 

 BB. Habit of foliage strict. 

 c. Width of Ivs. 10-12 lines. 

 Bigelovii, Wats. Trunk unknown; Ivs. thick, flat, 

 3-4 ft. long, 10-12 lines wide above the base, with a red, 

 horny entire margin. 



cc. Width of Ivs. 5-6 lines. 

 recurvita, var. stricta, Lem. (Pincenictitia glaftca, 

 Hort.). Lvs. shorter and narrower than typical JY, re- 

 curvata, 2-3 ft. long, glaucous. 



AA. Lvs. 2 lines wide. 

 Hartwegiina, Hemsl. (Dasylirion junceum, Zucc). 

 Trunk unknown: lvs. 2 ft. long, with only 7-9 veins 

 instead of about 50. y^^ j^^ 



2V. Beldingi, Brandg. Aborescent, branching freely: trunk 

 columnar, 1-1^^ ft. in diam., 8-1.^ ft. high: branches short 

 bearing munerous old and new leaves towards the ends: leaves 

 glaucous, a yard or more long, ^ in. wide, flat. thiu. tapering 

 to the point, serndate on margins, about 50-nerved, weak and 

 recurved: panicle compound, 6 ft. long or more: fruit emargi- 

 nate: seeds round-ovate, not bursting the cells. Mountains of 

 the cape region of Lower California. Apparently nearest N. 

 Bigelovii. from which it differs in the thinner, more flaccid 

 le.ives, and the very much greater size. 



T. S. Brandegee. 

 NONESUCH, or Black Medick, is Medicago lupulina. 

 Nonesuch rarely means l/ychnis Chalcedonica. 



NOFALEA (from the Mexican name of the Cochineal 

 Cactus). Cactilceir. A genus of 4 or 5 species, often 

 placed with the Opiintias, but differing from the latter 

 in having h-inrs Inni^^rr than the perianth, as well as in 

 many minor di-t;iils. \;itives of the West Indies and 

 Mexico. N. coccinellifera, Salm., an arborescent, flat- 

 stemmed plant, with a somewhat cylindrical trunk 

 6-10 in. in diam., is widely grown in semi-tropical coun- 

 tries, but is rarely found in the U. S., and then only in 

 the largest collections of Cacti. It is chiefly interesting 

 in being one of the important food plants of the cochi- 

 neal insect. B.M. 2741, 2742 (as Cactus cocliinellifer).

NORTH CAROLINA, HORTICULTURE IN. Fig. 

 1493. Occupying the sunny slope eastward from the 

 highest mountains east of the Mississippi, North Caro- 

 lina has a greater variety in soil and climate than most 

 other states ; hence the hortictiltural capabilities are 

 varied accordingly. In the region of high plateaus, 

 ranges and valleys lying between the Blue Ridge and 

 the Great Smokies, which mark the line of Tennessee,
