witness the abundance of Erica from the Cape, now com- 

 mon in every greenhouse, and many other charming 

 shrubs, cultivated in a peat soil. He conceived the whole 

 order to be nearly confined to one meridian, from the 

 North Cape of Lapland, to the Cape of Good Hope ; but 

 he is incorrect in saying there are very few in North 

 America, and none in the East or West Indies. 



llalesia, Styrax, Spathelia, Citrus and Garcinia are 

 subjoined as an appendix to the Bicomes, but there is al- 

 lowed to be a considerable distance between them, and 

 the last is erased in the Gen. Plant, as having opposite 

 leaves. Giseke records, p. 345, that when Linnaeus said 

 no Erica grew in America, he asked him whether Hud- 

 sonia were not an exception to this ? On which he took 

 that genus from his herbarium, and after contemplating 

 and replacing it, wrote something, Giseke knew not what, 

 in his Genera Plant arum. We find what he wrote to be 

 as follows : " Videnda Hudsonia, Empetrum, Ilex, [tea." 

 It is interesting to be thus able to trace the thoughts of 

 such a man. He was moreover correct .as to the genus 

 Erica itself, of which no species has been detected in 

 America. 



Order 19. Hesperide./e. Of this nothing is said in 

 the lectures. The original genera are Eugenia, Psidium, 

 Myrtus, and Caryopliyllus ; to which Giseke has added 

 Calyptranthes and Legnotis of Swartz. Melaleuca also 

 strictly belongs to this tribe ; though, by a strange error, 

 referred in the Mantissa to the 40th order, and yet said 

 to be akin in Ginora, which belongs either to this or the 

 17th. Philadelphus is subjoined as forming a section 

 by itself, and still with a mark of doubt. The discoveries 

 in New Holland have thrown much light on this fine order 

 of aromatic and elegant shrubs, of which the Myrtle is a 

 familiar type. Linnaeus intended to remove Garcinia 

 hither. 



Order 20. Rotaces:. The lectures are also deficient 

 as to this order. It consists of Trientalis, Centunculus,
