KEVISION OF. THE NATURAL ORDER HEDERACE.E 
By Berthold Seemann, Ph.D., E.L.S. 
(Continued from p . 239.) 
On the Genus Sciabobendron. 
(Plate LXX.) 
I first met with this tree in 1846, at Panama, where it is known by 
the name of Jobo de lasarto, and commonlv used for making fences, — 
poles stuck in the ground taking root readily, and growing very fast. 
On the 22nd of March, 1847, I sent a collection of Panama woods 
to the Kew Museum, and n. 33 of that collection were specimens of 
this tree. But though I looked carefully and frequently for flowers, 
1 could never find any. Mr. Sutton Hayes also records amongst his 
notes that he had known the tree for years, without being so fortunate 
as to find any flowers on it. My friend Dr. Duchassaing was the first 
who gathered some imperfect flowering specimens, which passed into the 
hands of Professor Grisebach, who referred them, in my * Bonplandia,' 
to a new genus of JraUacea {Sciadodtndron). The late Mr. Sutton 
Hayes obtained better specimens of the flowers, which he sent to Eng- 
land, and which I found without a name both at the British Museum 
and at Kew. There being no leaves of the plant in these herbaria, I 
did not fail, when, in May last, at Panama, to collect specimens of 
them, so that T am now able to publish a plate of this common, but 
so little known tree, that Bentham and Hooker, in the recently-pub- 
lished Part of their • Genera Plantarum,' were obliged to refer it 
amongst the doubtful genera. 
Sciadodeiidron belongs to the little group of Araliacea proper (dis- 
tinguished from the Hederace* by the imbricate activation of the 
Petals), and from Jraiia, SCdboearpa and allied genera by its 10- 
merous flowers.
