§ 280. Diclytra Dielytra, Dicentra—To verify references is 
always important. A little mistake was made in my Genera Illustrata, 
i, 120, and Manual, 61, through my inability to do so. Until now I 
possessed no copy of Romer’s Archiv der Botanik, nor did I know 
of any copy in America. Relying upon Bernhardi, who in Linnaea, 
viii, 458, declared that Borkhausen’s name Diclytra was a misprint, 
and that the name should be written Décentra, I wrote in the Genera 
that the name in its original form was a slip or typographical error, 
but that the derivation was correctly given by Borkhausen. In the 
Manual the statement is similar. We have now Romer’s Archiv, and 
the essential parts of Borkhausen’s paper were reprinted by Pfeiffer, 
whose article is duly referred to by Watson in his Index. ‘The cor- 
rection I have tomake is this. ‘The error in Borkhausen’s paper 
can hardly be typographical. Three times the name is printed 
Diclytra; and this is said to be composed of “07s, zwey, und 
nxAvrpov, Sporn.” There is, of course, no such Greek word: the 
word “Sporn,” spur, throws out Sprengel and Reichenbach’s conjec- 
ture that €Avrpov was meant; that the printer could have changed 
Dicentra and uévrpov into Diclytra and uAvtpov seems most 
unlikely. It is more probable that Borkhausen fancied there was 
such a word. 
_ There is diversity in the orthography of Borkhausen’s name. In 
Romer’s Archiv the name appears as Borckhausen, and it is so given 
by Bernhardi: it is so printed on the title page of his own 
Botanisches Worterbuch. But Endlicher, Pritzel, and the Royal 
Society’s Catalogue write Borkhausen, and Pfeiffer, in Bot. Zeitung, 
noticing the two forms, adopts this as the more correct. A. GRAY. 
§ 281. Sporting Trillium grandiflorum.—The note on the 
forms of Trillium grandiflorum collected by Mr. Shoop, which I 
contributed to the November No. of the BULLETIN, has brought to 
me a letter from an old correspondent, Mr. E. L. Hankenson, of 
Newark, Wayne Co., N. Y., along with a remarkable series of abnormal 
variations of the same species. They all have conspicuously petioled 
leaves; and this peculiarity is the only abnormal feature in some of 
the specimens, except the smaller size which is common to all of 
them. But the acute base and acuminate apex of every leaf keeps 
them all apart from 7. nivale. The same clump furnishes speci- — 
mens: 1, with a whorl of three petioled leaves in the ordinary posi- 
tion ; 2, with peduncle as a naked scape, and two very long petioled 
leaves from the root-stock along with the scape; 3, the same with a 
solitary leaf of this sort. These variations are rather common in 
Mr. Hankenson’s observation. Monstrous forms with chlorosed 
perianth are common. In one of these the tip of a rootstock sends 
up two filiform stems, side by side: one of them terminates in a 
whorl of three long-petioled leaves, the petioles of about the length 
of the blade; the other is terminated by a blossom with foliaceous 
(green and white) petals, imperfect stamens and a more depauperate 
imperf stil. Other leafless flower-stems bear only a depauperate 
green flower ; the perianth of six similar green leaves; the stamens 
not transformed but abortive as to pollen ; the pistil sometimes reduced ©
