described as having a paniculate inflorescence (the inflorescence 

 of D. aluminosa, if branched at all, is branched only at the very 

 bottom) ; moreover, the pedicels are said to equal or exceed the 

 calyx in length (those of D. aluminosa are exceedingly short) and 

 the stamens are about forty. S. fcrruginea with broader leaves 

 has stout ferrugineous spikes (Z). aluminosa has them very slender) 

 and larger flowers. The description of S. syringoides fits our 

 plant well except for its young branches being alluded to as 

 ferrugineous-tomentose, a condition impossible to affirm in the 

 other's case, what indications of young branches there may be 

 pointing to ordinary pubescence. On the whole, I think it likely 

 that D. aluminosa may be S. syringoides, and as such it has been 

 written up provisionally in the National Herbarium. ^

Brand places this at the end of his monograph t among the 

 doubtful species with the note: " Sine dubio optima species, sed 

 adhuc specimina non sunt nota." There is a sheet of this in the 

 National Herbarium, and although, the flowers being in young 

 bud, the specimens leave something to be desired, one can deter- 

 mine the affinity of the species with but little doubt as to the 

 validity of the conclusion reached. 



Of course the organs Loureiro describes as a 3-leaved outer 

 calycine whorl are, as in the last case, three bracts. The rest of 

 the characters, generic and specific, given in the description are 

 in the main correct so far as the specimens enable one to tell, 

 except that the flowers are said to be hermaphrodites and females 

 on different plants ; so far as I have been able to study the 

 matter, they seem to be either hermaphrodite or male, and so to 

 answer the " polygamo-masculi " sexual character given by Brand 

 as of occasional occurrence in the genus. Although, owing to the 

 early state of the flowers, the androecium cannot be properly 

 examined, there seems no reason to doubt that our plant is refer- 

 able to § Bohua, The description is appended.
