Distichostemon. 1405 



lobato. Gemmulae in loculis binae, angulo central! superpositae, illis generis Dodonaeae 

 simillimae. Fructus 3( — 6)-locularis, capsularis, obovoideo-triqueter, brevissime 

 stipitatus, densiuscule sed breviter hirsutus, loculis dimidio superiore herbaceo-alatis, 

 alis infefne angustatis mox nuUis vel subnuUis, coriaceus, ruptura parietum dehiscens 

 (loculicidus), 3-valvis, septis membranaceis purpureis nitidis persistentibus. Semina 

 2 globosa, nigerrima, nitidissima, basi tumescentia annulari circumdata. 



Frutices alti, ramis teretibus gracilibus, novellis flavido-cane tomentellis, demum 

 cinerascentibus nigro-rimosis glabratis. Folia alterna, brevissime petiolata, simplicia, 

 parva, e basi cuneata oblongo-elliptica, obtusissima, apice parum retuso minutim 

 mucronulata, integerrima (vel in D. filamentoso crenato-dentata), sicca margine extremo 

 angustissime revoluta, nervis lateralibus retique venarum subtus prominulis, opaca, 

 chartacea, subtus praesertim cano-tomentella, juvenilia immo subvelutina. Inflores- 

 centia pauciflora, axillaris vel terminalis, rhachi gracili tomentosa. Pedicelli breves, 

 tenues. #
