and Writings of Dr Olaus Swartz, 
on the other genera, Trans, of the Soc. ofUpsal , vi. 59. ; Vetensk. 
Acad. Handl. 1800, ii. p. 202. ; Schrad. neues Journ. i. 1). 
Assisted by his efforts and illustrations, R. Brown, and the cele- 
brated Richard, afterwards threw new light upon this family. 
No one could have better defined and illustrated the characters 
and species of the genera Phyllachnes , (Schrad. Journ. 1799, i. 
273. ; Annals of Botany, i. 286.) : v Forstera , (ibid. 291), Ehr- 
harta , (Trans, of Lin. Soc., vi. 40.) : Stylidium, (Berk Magaz, i. 
47., v. 89.): Linconia , (ibid. iv. 85., v. 283.): Ochroma , (Vetensk. 
Acad. Handl. 1792, 144.) : Stylosanthis , (ibid. 1789, 295.) : Ao- 
landra , (ib. 1787, 300.): Chloranthus , (Philos. Trans., lxxvii. 
359.) ; as well as of many others. In constructing new genera, 
he was cautious and circumspect, having none of the spirit of 
innovation which prompts us to elevate every little point of diffe- 
rence to the dignity of a generic character. Acting upon firm 
principles, he considered those characters only as stable, in which 
he saw true and essential differences ; so that the genera which 
he established, were never afterwards reduced. 
The genera of Phaenogamous plants, formed by Swartz, are 
the following : Acidoton , Ardisia , Porosimum , Bumelia , Calyp- 
tranthes , Cephaelis , Chloranthus , Chloris , Coccocypselum , Cory - 
cium, Cranicliis , Cymbidium , Dendrobium , Diplodium , Dispe - 
m, Ernodea , Epistylium , Hedyosmon , Hedwigia , Hoffmannia , 
Hypelate , Labatia , Lacistema , Legnotis , Leptanthes , Linociera, 
Lithophila , Meriana , Meyera , Microtea , Myrodia, Ochroma , 
Oncidium , Petaloma , Picramnia , Pterygodium , Rochefortia , Ao- 
landra , Stelis, Stylidium , Stylosanthes , Tenaecium 0 Thrinax , 
Tetranthus , Tricera , Trixis , Valentinia , Vanilla , Wallenia. 
The vast treasures which he had collected in the West Indies, 
he first described in his iVom Genera et Species Plantarum, 
Holm. 1 788 ; afterwards in the Observations Botanicce , Er- 
lang. 1791 ; and lastly, in the admirable work, Ffora Indice 
Occidentalism vol. i.-v., Erl. 1797,-1806. 
In extricating innumerable new genera and species, elaborat- 
ing genuine characters, improving them, detecting synonymes, 
and adding the most beautiful descriptions, he laboured with such 
indefatigable industry, that he often added figures, delineated 
by himself, with great skill, as he was sufficiently expert in the 
art of drawing.
