the larvae; or to examine the plants with a lantern at 

 night, and to pick off such as are visible. Those that 

 live in the hearts of the plants cannot be removed with- 

 out the destruction of the parts in which they lie. In 

 the protection of Turnips, and other field crops, rooks 

 and partridges afford the best aid, though starlings and 

 other birds also eat not a few larvae. 



NODE. That part of a stem from which a leaf, com- 

 plete or incomplete, arises. 



NODOSE, NODULOSE. Having many nodes, or 

 knots. 



NODULES. Small hard nodi, or knots. 



NOISETTIA (named after Louis Claude Noisette, 

 1772-1849, an eminent French cultivator of fruit trees, 

 author of " Le Jardin Fruitier "). OBD. Violariece. A 

 small genus (two species) of erect, almost simple, stove 

 sub-shrubs, inhabiting tropical and Northern sub-tropical 

 America. Flowers in the axils, shortly racemose or fasci- 

 culate ; pedicels articulated above the middle. Leaves 

 alternate, simple. The species thrive in a thoroughly 

 well-drained compost of sandy loam and leaf mould, and 

 require a light place near the glass. Propagated by 

 cuttings, inserted in sand, under a hand glass, in heat. 

 N. longifolia (long-leaved), fl. cream-coloured or white, in 



bundles; spur awl-shaped. I. lanceolate, serrated, acute, tapering 



into short footstalks, ft. 1ft. to lift. Cayenne, 1824. 



NOLAN A (from nola, a little bell; alluding to the 

 shape of the corolla). STNS. Neudorfia, Sorema, 

 Teganium. OBD. Convolvulacece. This genus consists 

 of about eight species of hardy, glabrous or pubescent, 

 often diffuse or prostrate herbs, natives of Chili and 

 Pern. Flowers whitish, bluish (or pink?), in the axils, 

 shortly pedunculate ; calyx campanulate ; corolla broad, 

 almost funnel-shaped. Leaves solitary or twin, sessile or 

 petiolate, entire, flat, sometimes slightly fleshy. The 

 species are of easy culture in any moderately good garden 

 soil, and in a sunny situation. Seeds should be sown 

 in the open border during April or May. The species 

 best known to cultivation are the following : 

 N. atriplicifolia (Atriplex - leaved), fl. large; throat white, 



yellow inside. Summer. 1. spathulate ; radical ones large. 



Stems procumbent, rather villous. Peru, 1834. SYN. N. grandi- 



flora. (S. B. F. G. ser. ii. 305.) 



N. grandlflora (large-flowered). A synonym of N. atriplicifolia. 

 N. lanceolate (lanceolate).* /. blue, white, green, solitary in 



the axils. July. I. twin, lanceolate, semi-ainplexicaul, obliquely 



adnate at base' ft. 6in. Chili, 1860. (B. M. 5327.

 Stems filiform. Plant clothed with viscid down. Chili, 1824.

NOLANACEJE. Included under Convolvulacece. 



NOLINA (named after P. C. Nolin, a French botanist 

 of the last century). SYN. Roulinia. OBD. Liliacece. 

 This genus is included, by Mr. Baker, tinder Beaucarnea. 

 There are about a dozen species, natives of Mexico, 

 Texas, &c. N. georgiana is a showy, half-hardy plant, 

 with a very large tunicated bulb; it would probably 

 prove hardy in favoured localities in Southern counties. 

 Under glass, in a cool house, it thrives in a well-drained 

 sandy -loam compost, and, during the season of rest, water 

 should be sparingly administered. Increased by offsets. 

 N. longifolia and N. recurvata are described under Beau- 

 carnea (which see). 



N. georgiana (Georgian).* JL whitish, small, disposed on an 

 erect stalk, 2ft. to 3ft. high, and branching at the top into a many- 



rnicle with spreading branches. May. I. dry, harsh, 

 narrow, strap-shaped. Georgia, 1812. (G. C. n. s.,

NONNEA (named after J. P. Nonne, of Erfurt, 

 1729-1772, a German writer on botany). Sometimes 

 spelt Nonea. STNS. Echioides, Oscampia. OBD. Bora- 

 ginece. A rather large genus (upwards of thirty species 

 have been described) of half-hardy or hardy, annual 

 or perennial, hispid or villous, erect or often diffuse, 

 herbs, natives of Europe, North Africa, and Western 

 Asia. Flowers pink, blue, white, or yellow, erect ; 

 cymes at first dense, at length often separating into 

 elongated, leafy-bracted branches; corolla tube cylin- 

 drical, lobes imbricated. Leaves alternate. N. rosea is 

 probably the prettiest of the two or three species grown 

 in this country. For culture, see Anchusa (under 

 which several of the species are often classed;. 

 N. rosea (rose-coloured).* fl. rose-coloured, with a yellowish-white 

 throat. Summer. J. oblong, obtuse, ft. 6in. to!2in. Asia Minor, 

 <fec. Diffuse hardy annual. SYN. Anchusa latifvlia. A. versicolor 

 (B. M. 3477) is a form in which the flowers are red when in bud, 

 but turn a fine blue when fully expanded. 



NOONFLOWES. See Tragopogon prateiisis. 

 NOFALEA (from Nopal, the Mexican name for a 

 Cactus). ORD. Cacteos. A small genus (three species) of 

 fleshy, stove shrubs, inhabiting the West Indies, Mexico, 

 and tropical South America, one being largely cultivated 

 in the tropical regions of the globe. The species are 

 allied to Opuntia, from which they differ in having erect 

 and connivent, not expanding, petals, and in the stamens 

 being shorter than the style, but longer than the corolla. 

 Flowers scarlet ; perianth inclosed. Leaves small, squami- 

 form, on the younger tubercles. Branches articulated; 

 joints compressed, obovate or oblong; tubercles bearing 

 a few small prickles. Nopaleas thrive under conditions 

 which are found suitable for Opuntias, and most other 

 Cacti. A thoroughly well-drained soil, amongst which 

 should be incorporated a fair proportion of lime rub- 

 bish (which acts as a draining agent, and also supplies 

 the lime which, in the form of oxalate, is found in such 

 large quantities in the stems of old plants), is all that 

 is needed. Unlimited sunlight, a fair supply of water 

 when in growth, and a less quantity when at rest, com- 

 plete the necessary conditions. 



N. coccinellifera (cochineal-bearing), fl. lin. in diameter. 

 August. I. soon falling off, leaving a white scar and a tuft of 

 short wool and bristles. Stem and older branches ashen-grey, 

 nearly cylindrical, the younger parts being deep green and flat ; 

 joints 5in. to 1ft. long. ft. 8ft. to 10ft. West Indies, 1688. This 



Elant is widely grown as food for the cochineal insects, of which 

 irge quantities are reared on it. SYN. Opuntia coccinellifera 

 (B. M. 2741, 2742, under name of Cactus cochinell\fer.)
