G84 SUPPLEMENT.— HIPPOCASTANACE^. 



. 5. A. glahrum. — We have the same species from Douglas's collection. 

 It is said to come from the Blue Mountains of Oregon. The specimens are 

 more perfect than those of Dr. James (but like them are in fruit only) : the 

 wings of the fruit are a little longer in proportion, and erect rather than 

 divergent. 



8. A. saccharinum was wholly established by Linliseus upon a specimen 

 (leaves only) received from Kalm ; which specimen, we find on inspection, 

 belongs to A. dasycarpum ! Still as the A. saccharinum of Wangenheim, 

 Michaux, and all succeeding autliors, is the true Sugar- Maj^le^ a change in 

 the application of .the name would be unwarrantable. 



10. A. rubrum. — The A. rubrum of Spach is a form of this species with 

 the leaves rather more deeply lobed and incised than usual, and the flowers 

 only reddish ; while his A. sangujneum is the A. rubrum as figured in the 

 Sylva of the younger Michaux. — After our var. /?. add : 



y. leaves rather large, rigid, cordate at the base, densely tomentose beneath, 

 the tomentum somewhat persistent.^A. rubrum y. ? (Drummondii), Hook. 

 Sf Am. ! in. jour. bat. p. 199. — (Louisiana, Drummond! Prof. Carpenter!) 

 This and our /?. are certainly only forms of this somewhat polymorphous 

 species. 



11. A.harhatum (Michx.!) should be discarded as a species, it having 

 been founded (as we had indeed long suspected) upon the flowers of A. sac- 

 charinum, the fruit of A. rubrum, and a leaf of something else, apparently 

 of A. spicatum, (v. sp. in herb. Michx. 2^ropr. 6^- herb. Richard.)

1. N. aceroides. — Add syn. N. fraxinifolium, Guimp. Otto, S^ Hayne, 

 holz. t. 95. 



2. N. Californicum : leaves 3-foliolate, pubescent-tomentose especially 

 beneath ; the petioles and young branches very velvety ; leaflets ovate, 

 acuminate, 3-lobed, incised and serrate ; fruit oblong, pubescent, rather 

 shorter than the obliquely obovate almost erect wings. — Hook. Sf Am. J bot. 

 Beechey, suppl. p. 327, t. 77. — Fine specimens in fruit having been found in 

 Douglas's collection, a more complete character is given of this species, which 

 is proved to be totally distinct both froip N. aceroides and N. Mexicanum, 

 which Hooker has also received from Andrieux. 



(Order MALPIGHIACE^.) 



Banisteria microphylla (Jacq.) is said to be a native of Carolina, we think in. 

 correctly. Yet there is a Malpighiaceous plant from Fraser in Mr. Bentham's 

 herbarium, said to come from Carolina, which Mr, Adr. Jussieu informs us is 

 Heteropteris purpurea, H. B. ^ K., and probably also Banisteria microphylla, 

 Jacq. 



Order HIPPOCASTANACE^. 



2. UNGNODIA, p. 253, should be UNGNADIA. , 



Ungnadia speciosa, was so called by Endlicher in memory of Baron 

 Ungnade, many years since Aiistrian Ambassador at Constantinople, who 

 was the first to introduce the Horse- Chestnut into Western Europe.
