antia. Ovarium villosissimum. Styli 3, pilosissimi, apice 

 glabri breviter fissi. Capsula villosa, bracteolis brevior. — 

 I should have taken this for the T. odorata of Richard, with 

 whose very short and imperfect diagnosis it agrees, but that 

 Kunth states his T. moU'is to be very iiear to T. odorata^ 

 which would lead one to infer that the latter is a petioliflo- 

 rous species. T. tomentosa, Humb. et Kunth, may be the 

 same as my T, parvifiora, but that Kunth describes it as 

 having hexamerous flowers. He saw however but one 

 flower; and that may liave been hexamerous by accident. — 

 Savannahs of the Rupunoony; Schornburgk. — French Guiana, 

 Herb. Par. n. 121. 



The three preceding species, as well as Gardner's n. 2179 

 from Piauhy, which is I believe an undescribed one, belong 

 to De Candolle's second group, with persistent bracteolas, as 

 in the petioUjiuroe^ but with free uniflorous axillary pedun- 

 cles. De Candolle's third group has generally the inflores- 

 cence and habit oi Piriqiieta, and can only be distinguished 

 from that genus by the inspection of the styles. I have no 

 species of this group in the Guiana collections before me; but 

 besides tlie West Indian T^ cistoides, and several Brazilian 

 ones, in my herbarium, I refer to it, as far as I can ascertain 

 from my specimens, the Nos. 1665, 1666, 1668, and 24)16 of 

 Gardner, from Ceara, and 2172, 2174, and 2177 from Piauhy. 



The T.salicifolia, St Hil., (which I have among Tweedie's 

 Rio Janeiro plants, and is the Corchorus grandijlorus, Spreng., 

 in my set at least, of Martius's Herbarium Florae Brasiliensis,) 

 the T. sidafolia, St Hil., and Gardner's n. 2173 from Piauhy, 

 a new species allied to the last mentioned one, are remark- 

 able from their two or many-flowered peduncles. In other 

 respects they agree with De Candolle's third group.

 Sands of the Essequibo; Schornburgk, n. 189. French Guia- 

 na; Herb. Par. n. 44, and probably Pernambuco; Gardner, 

 n. 929; but in the latter instance the flowers of my specimen 

 are all fallen off".
