BUD 



Tlie first species rises with an upright stalk to 

 the hciehi ot eight or ten feet, wliich at boltoni 

 15 lia^ieous, having a piirphsh bark, covered 

 with a whitish powder, which comes off w lien 

 handled ; the upper part of the stalk is gar- 

 nished wiih leaves at everv joint, the foot-stalks 

 half eiiibraciiiii them at ilieir base, braiichinsj 

 out iiitt> several smaller, like those of the com- 

 mon parslev, and set with leaves like those of 

 lo7agc, but smaller, of a grav colour; tlie top 

 of the stalk is terminated by an umbel of yellow 

 flowers, which are succeeded bv oblonc chan- 

 nelled seeds, having a thin membrane or wing 

 on their border. It Howcrs in Aiiirust, but 

 does not produce seeds in this climate. When 

 aiiv part of the plant is wounded, there issues a 

 little tliin cream-coloured milk, which is the 

 druffffalhaniun. It is a native of the Cape. 



The second rises with a woodv stalk about two 

 feet high, with leaves at each joint branchinjr 

 out like those of the former : but the leaflets are 

 narrow and indented, like those of bastard 

 hemlock. Tlie stalk is terminated bv a larse 

 umbel of small white flowers, which are suc- 

 ceeded by seeds as in the former sort. It is a 

 native of the Cape, and flowers in July. 



Cultu)-e. — ^These plants are propagated bv 

 seeds, which should be sown in pots filled with 

 light loamv earth, as soon as they are procured, 

 which if in aiitunm, thcv should be ])lunged in- 

 to a bed of tanner's bark, where the heat is 

 nearly gone, and be screened from frost in 

 winter. The plants come up in the spring, and 

 about the middle of April are fit to remove, 

 when thev should becarefullv shaken out of the 

 pots, and be planted each into a separate small 

 pot, filled with the same sort of earth, then 

 plunged into the tan asrain, water being given 

 to settle the earth to the roots, as well as shade 

 in the daytime, until thcv have taken new root. 

 Thev must then be graduallv inured to the open 

 air, into which thev should be removed in June, 

 being placed in sheltered situations where they 

 mav remain till autumn, when thev must be 

 taken into the orcen-house, and be exposed to 

 the sun and air as much as possible, but defended 

 from frost. 



In winter they should have but little water, 

 as much wet injures them ; but in summer, 

 when exposed to the open air, thcv must be 

 frequently refreshed with water in drv weather. 



These plants attord varietv in the irreen-housc 

 in winter, and, when placed out in summer 

 with other green-house plants, have a good ef- 

 fect, especially when grown to a good size. 

 They mostly flower the third vear from seeds, 

 but their flowfrs are produced so late in sum- 

 mer, that the seeds seldotu form before the cold 



coinns on : in warm summers, howovor, th«f 

 second sort will perfect seeds, if it stand in a 

 warm sheltered situation. 



BUCKNtllA, a genus containinsja plant of 

 the exotic shrubby kind. 



It belongs to the class and order Didijnamin 

 yln^in</7i-rm'!a, and ranks in the natural order of 

 I'cr^iinattp. 



Its characters arc : that it is a one-leafed, ob- 

 scurely five-loothcd, scabrous, permanent pcri- 

 anthiuin: the corolla is monopetilous: tubeverv 

 loiiiT, filiform, bnw id, border flat, short, five-cleft, 

 equal : the two upper divisions very short, reflex ; 

 the three lower cordate, in-.trly equal : the staiiiitia 

 consist of four filaments, very short, in the throat 

 of the corolla ; the two upper ones prominent 

 outward, and short : the anthers are oblong 

 and obtuse : the pistillum is an ovatc-oblong 

 germ : the style filiform, the length of the tube : 

 the stiema obtuse: the pericarpium is an acumi- 

 nate capsule, covered, two-celled, gaping at 

 the top into tw o parts : partition contrary : the 

 seeds are numerous and ani:ular : the receptacle 

 is fastened to the middle of the partition. 



There is onlv one species for our use, B. vis- 

 cosa, Clammy Bucknera. 



It rises with a shrubby upric;ht branching 

 stalk, with slightly indented, linear, spear- 

 shaped leaves. The flowers are purple with 3 

 yellow eve. It has not much beauty, but oc- 

 cupies little room, and flowers during most of 

 the summer months. It was found at the 

 Cape. 



Culture. — This plant may be readily increased 

 by setting cuttings from the young shoots in 

 summer, in pots of light mould, care being 

 taken to \vater and shade tlieni well till they 

 have stricken roots, and become well established j 

 when thev should be removed into other pots 

 separately, and be protected during the winter 

 season in the green-house. 



BUD, the eye or spot whence a branch is 

 sent oft' in trees or plants. It is the Injirrna- 

 culum or winter-cradle of the embrvon shoot, 

 being mostly c()\ered by scaly lamina?, and 

 sometimes a resinous varnish, that serves to 

 protect it during the winter from the effects of 

 cold and moisture, as well as the attacks of 

 insects. Thev are either leaf-budsor'lowcr-buds, 

 or both in the same covering. These cmbryoii"? 

 have been denoniinaied the " viviparous proirenv 

 of plants," by Doctor Darwin, in contradi- 

 siiueiion tothose from seeds, w hich he li;is termed 

 " oviparous progeny." 



The bud, according to Doctor Hooper, at 



first lies conc(.-r.led in the body of the tree or 



branch between the barks, being very small, 



and covered with the hark in the same wav ^*
