The first species rises with an upright stalk to 

 the height of eight or ten feet, which at bottom 

 is ligneous, having a purplish bark, covered 

 with a whitish powder, which comes off \v hen 

 handled ; the upper part of the stalk is gar- 

 nished with leaves at cvervjoint, the foot-stalks 

 half embracing them at their base, branching 

 out into several smaller, like those of the com- 

 mon parsley, and set with leaves like those of 

 lovage, but smaller, of a gray colour ; the top 

 of the stalk is terminated by an umbel of vellow 

 flowers, which are succeeded by oblong chan- 

 nelled seeds, having a thin membrane or wing 

 on their border. It flowers in August, but 

 does not produce seeds in this climate. When 

 any part of the plant is wounded, there issues a 

 little thin cream-coloured milk, which is the 

 drug galbanum. It is a native of the Cape. 



The second rises with a woody stalk about two 

 feet high, with leaves at each joint branching 

 out like those of the former ; but the leaflets are 

 narrow and indented, like those of bastard 

 hemlock. The stalk is terminated by a large 

 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. 



Culture. — These plants are propagated by 

 seeds, which should be sown in pots filled with 

 light loamy earth, as soon as they are procured, 

 which if in autumn, they should be plunged 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 they should be carefully 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 again, water being given 

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

 in the daytime, until they have taken new root. 

 They must then be gradually inured to the open 

 air, into which they should be removed in June, 

 being placed in sheltered situations where they 

 may remain till autumn, when they must be 

 taken into the green-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, they must be 

 frequently refreshed with water in dry weather. 



These plants afford variety in the green-house 

 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 year from seeds, 

 but their flowers are produced so late in sum- 

 mer, that the seeds seldom form before the cold 



comes on : in warm summers, however, the 

 second sort will perfect seeds, if it stand in a 

 warm sheltered situation. 



BUCKNERA, a genus containing a plant of 

 the exotic shrubby kind. 



It belongs to the class and order Didynamia 

 jingiospermia, and ranks in the natural order of 

 Personate? . 



Tts characters are : that it is a one-leafed, ob- 

 scurely five-toothed, scabious, permanent peri- 

 anthium: the corolla is monopet.dous: tube very 

 long, filiform, bowed, borderflat, short, five-cleft, 

 equal : the two upper divisions very short, reflex ; 

 the three lower cordate, nearly equal: the stamina 

 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 ovate-oblong 

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

 the stigma obtuse: the pericarpium is an acumi- 

 nate capsule, covered, two-celled, gaping at 

 the top into two parts : partition contrary : the 

 seeds are numerous and angular : the receptacle 

 is fastened to the middle of the partition. 



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

 coxa, Clammy Bucknera. 



It rises with a shrubby upright branching 

 stalk, with slightly indented, linear, spear- 

 shaped leaves. The flowers are purple with a 

 yellow eye. 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 water and shade them well till they 

 have stricken roots, and become well established; 

 when they 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 off in trees or plants. It is the hyherna- 

 culum or winter-cradle of the embryon shoot, 

 being mostly covered by scaly laminae, 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. They are either leaf-budsorflower-buds, 

 or both in the same covering. These embryon? 

 have been denominated the " viviparous progeny 

 of plants," by Doctor Darwin, in contradi- 

 stinction to those from seeds, which he has termed 

 " oviparous progeny." 



The bud, according to Doctor Hooper, at 



first lies concealed in the body of the tree or 



branch between the barks, being verv small, 



and covered with the bark in the same way as
