The descriptions of the two following species will be given in 

 the third volume of the * Contributions to Botany :' — 



1. Detandra latifolia, nob. in Ann. Nat. Hist. ser. 3. xiii. 124. — 



In Brasilia: v. s. in herb. DeCand. ^ , Babia (Blanchet). 



2. ovata, nob., loc. cit. ; — Sychnosepalum niicrophyllum, 



Eichl. in Mart. Fl. Bras. fasc. xxxviii. p. 204, tab. 44. fig. 5. 

 — In Brasilia : v. s. in herb. De Cand. ^J , Bahia (Blanchet, 

 3178 a). 



54. Syrrheonema. 



This genus was proposed by me for a climbing plant having 

 roundish cordate leaves, with a supra-axillary inflorescence, 

 consisting of from three to six short fasciculated peduncles 

 bearing generally three sessile flowers, which are small, with 

 six tomentose imbricated sepals, no petals, and three stamens 

 united for half their length into a central column*, the free 

 portions being nearly erect, fleshy, and semiterete, each having 

 four distinct anther-lobes quadrately disposed and imbedded 

 introrsely in their summits. There is some resemblance in this 

 latter feature to the stamens of Jateorhiza ; but the analogy 

 extends no further. 



The genus approaches Detandra, Aristega, and Desmonema in 

 having three monadelphous stamens ; but it differs from them 

 in having no petals and in other particulars. In its inflorescence 

 (consisting of several fasciculated, axillary, simple peduncles) it 

 offers some analogy with Pycnarrhena and Antitaxis; but there 

 the peduncles are 1 -flowered, while here they bear from three to 

 six crowded, sessile, very small flowers.
