 cies, which name is said to mean an ants' nest ; the trunk 

 and branches are usually full of ants.) Aubl. 1 . p. 75. Juss. gen.

 and terminal, yellowish, large. 



1 T. GUIANE'NSIS (Aubl. guian. 1. p. 75. t. 29. Mart. nov. 

 gen. bras. 2. p. 119.) shrubby, glabrous; branches tetragonal ;

 Tachia, Gmel. syst. 247. Rcem. et Schultes, syst. 3. p. 163. 

 Leaves 8 inches long, and 2-3 broad. Corollas yellow. The 

 natives use the root, which is bitter, as a febrifuge. There are 

 drops of a yellow pellucid gum from the axils of the leaves, be- 

 neath the flowers. 



Guiana Tachia. Shrub 5-6 feet.

 or oblong-lanceolate, acute, downy ; flowers on short, axillary, and

 mant. 43. Browne, jam. p. 157. 2. t. 9. f. 2. Flowers yellow. 

 P. Browne remarks that this plant may be deemed a variation of 

 T. longifblia, they being so much alike in habit, the form of the 

 leaves is almost the only difference ; that they are always cor- 

 date, the upper ones only being ovate and sessile ; the corollas 

 are also rather larger. 



Heart-leaved Tachia. Fl. ? Clt. 1816. Shrub 2-3 feet. 



4 T. SWA'RTZII ; shrubby, glabrous ; branches terete ;

 lary ; segments of corolla ovate, acute, erect ; stamens much ex- 

 serted. 17 . S. Native of Jamaica, on the blue mountains.

 Corollas yellow. 



Stvartz's Tachia. Fl. June, July. Clt. 1793. Shrub 10 feet. 



Cult. These are elegant shrubs when in blossom. They 

 will grow freely in a mixture of peat and sand, mixed with a 

 little loam ; and cuttings strike root readily in sand under a 

 hand-glass, in heat. The species are difficult to keep through 

 the winter in this country, being very apt to damp off; but 

 to prevent this, as much as possible, they should be kept rather 

 dry in damp weather.
