them, which we conluss we d(i not, altliou^-h they have a 

 place ill the buoks. A very l.)eautiful species is IL. Iiibe- 

 raria, a herbaceous plant, native of South Europe, jiro- 

 (lueinu- ribbed leaves and yellow sun-roses of the most 

 exquisite beauty ; and only needing what may be termed 

 good conditions on the rockery. A tine j)lant intermediate 

 in character between a sun-rose and a cistus is llelian- 

 l/ieiinim (ici/iiuniJt'x, an erect-growing shrub about two feet 

 high, with ovate lanceolate leaves and flowers bright 

 yellow, with a blotch at the base of each petal. 



The species (jf Helianthemnm and Cistus are inostl}' 

 natives of South Europe, a very large proportion being 

 found on the sunny Spanish jieninsula. Hence a dry soil 

 and a. sunny aspect are natural rcipiirenients, and where 

 anything like a collection exists, it will be found impossible 

 to keep it together unless duplicate ])lants are reserved and 

 wintered under glass, a brick pit being the most suitable 

 for this purpose. But the common sun-rose is one of the 

 hardiest of garden jilants, a true native of Britain, and 

 spread over Europe from the Arctic 33irele to the Medi- 

 terranean. 



All these plants ma\' be easily jiropagated by cuttings 

 of the young shoots placed in a moderate heat. But to 

 insure variety, and to make jilants in consideralile quan- 

 tityj there must be sj'stematic saving and sowing of seeds. 

 It is a good plan with all choice subjects to sow the seeds 

 in pans or boxes, and give tlie young plants the shelter of 

 glass until they are somewhat advanced. But those who 

 cannot manage in this way may sow on a sandy, sunny 

 border u\ the month of April, and plant out the seetllings as 

 soon as they are large enough to be handled with safety. 

 Tlie soil should be sandy and calcareous for all except the
