There are many other species that may be 

 cultivated. 



The first has a perennial roof, branched, round, 

 knobl)?d, creeping, with very fine fibrils on every 

 side, partly white, partly red, having- an ovate, 

 acute, thick, rigid scale like a tooth at the knobs : 

 stipe partly subterraneous, partly standing out, 

 sometimes very little, sometimes several inches, 

 then procumbent and striking roots into the 

 ground, toothleted at the knobs like the root, 

 round, somewhat hirsute, red, closely toothlet- 

 ed above with the permanent joints of decayed 

 leaves, perennial, putting forth from its top 

 several airgrcgate leaves and scapes : the petiole 

 jointed, round, somewhat hirsute, red, especially 

 at bottom, from two to three inches long, al- 

 most upriglit but weak : the leaflets subscssile, 

 near half an inch long, wider, green and hirsute 

 «n both sides, shortly ciliate: the scapes one or 

 two, jointed at the base, round, somewhat viliosc, 

 red, the length of the leaves ; with embracing, 

 villose, jointed braetes above the middle : the 

 calycine leaflets oblong, acute, sometimes bifid, 

 somewhat hirsute, ciliate, purple at the tip, up- 

 right. It is a native of Europe. 



There is a variety with purple flowers. 



The second species has a perennial, creeping 

 toot, round, putting out capillary fibres at the 

 knots, branched : the stems from the root as it 

 creeps along several, roundish, slender, some- 

 what villose, purplish, finally branched, half a 

 foot high and more, upright, but being weak 

 often lying down, annual : the leaves are alter- 

 nate, a few sometimes opposite, ternate : the 

 petiole springing from a joint margined in front, 

 round, villose, spreading, from two to four inches 

 long, flaccid : the leaflets subpetioled, somewhat 

 hirsute on both sides with decumbent hairs and 

 green, ciliate, scarcely half an inch long : the 

 peduncles axtllary, jointed at the base, round, 

 villose, upright, about the same length with the 

 leaves, having from two to seven flowers in an 

 umbel, with a pedicel often branched. It is a 

 native of North America, flowering from June 

 to October. 



The third has the bulb ovate-triangular, even : 

 the stipe subterraneous, terminated by an umbel 

 of leaves and scapes : leaves several : the petiole 

 jointed at the base, channelled, smooth, from 

 two to three inches in length : leaflets obeordate, 

 sessile, green above, bright purple underneath, a 

 third part of an inch in length j lobes oblong. 

 Vol. II. 



rounded ; the scapes several, smooth, erect, skn- 

 der, half a foot in Icnjjih, umbellii'erous : the 

 Icnflcls of t!ic involucre few, acute, minute, 

 smooth : peduncles from two to four, one-Hower- 

 ed, sometimes villose, erect, about an inch in 

 length : the flowers of a yellow colour. It is a 

 native of the Cape. 



The fourth species has an ovate bulb, half an 

 inch long, covered with a black skin, within 

 which are frequeiitlv several bulbs : hence when 

 cultivated it has almost always many stipes: 

 these are out of the ground, have a few scales 

 on them, arc round, slender, hare a very few 

 hairs scattered over them, are six inches long, 

 sometimes leafless, sometimes having a single 

 leaf at top, when young almost upright, but af- 

 terwards wholly procumbent, terminated by a 

 dense umbel of leaves and flowers : leaves seve- 

 ral, upright,and spreading a little : petiole joirited 

 at the base, filiform, villose, from one to two 

 inches in length: leaflets subsessile, wedge-form - 

 linear, emarginate, at the edges and underneatk 

 appearing somewhat villose when magnified, 

 above smooth and dotted, underneath having 

 two orange-coloured calluses below the tip, 

 about half an inch in length : the scapes several, 

 jointed at the base, round, a little hirsute at top 

 with capitate hairs, in other parts with simple 

 ones, almost upright, longer than the petioles 

 and twice as thick ; braetes alternate, approxi- 

 mating, and ciliated at top with capitate hairs : 

 calj'cinc leaflets lanceolate, acute, erect, ciliate 

 and hirsute with capitate or simple hairs, green 

 with theedges blood-red, and two oblong orange- 

 coloured calluses below the tip connected at top. 

 It is a native of the Cape. 



The fifth has also an ovate bulb, loose, small, 

 loosely inclosed in a skin, from three to six times 

 the size of the bulb : the stipe subterraneous, 

 from one to three inches long, round, slender, 

 often bulbiferous, terminated by a detise umbel 

 of leaves and flowers : the leaves very many, 

 spreading or lying on the ground : the petiole 

 jointed at the base, densely villose, pale green, 

 from one to three inches long: the leaflets sessile, 

 quite entire, villose at tke edges, quite smooth 

 above, underneath somewhat hirsute and much 

 dotted, always green on both sides without any 

 other colour, half an inch and more in length : 

 scapes several, jointed at the base, round, some- 

 what villose, pale green, almost upright, longer 

 than the leaves : braetes sublinear, sharp, villotse, 

 approximately alternate at bottom : the calycine 

 leaflets lanceolate, acute, hirsute, ciliate, with 

 simple hairs, green with blood-red spots at the 

 edges, erect. It is a native of the Cape. 



I'he sixth species has the bulb in the young 

 plant ovate, covered with a brown skin, twice
