NOTES ON SOME ORIENTAL ONOSMAS. 
Br C. C. Lacaita, M.A., F.L.S. 
The following notes are based on the specimens in the Bailey 
Herbarium in the Museum of the Manchester University:— 
1. Sintenis: It. orient. 1890, No. 2543. Onosma sp. (left un¬ 
determined) from “ Egin in Armenia turcica, Hodschadurdagh in 
lapidosis 3 vi.” This is O. polyanthum DC. Prodr. x. p. 03, founded 
on Aueher-Eloy, no. 2306, from “ Cappodocia ad Euphratem,” Egin 
tigou, the west bank of the Euphrates at the great bend, just within 
the limits of ancient Cappadocia. Sintenis’s specimen is more ad- 
pressedly hairy than Aucher-Eloy’s, or than a similar one in herb. 
Kew collected by Montbret in 1834 in eastern Cappadocia. The 
leaves of the latter are spotted with white, rather distant tubercles, 
and are only slightly hairy in the intervals. In many species of 
Onosma, as in Echinm , the hairiness seems to wear off and the 
tubercles become more pronounced as the plant advances in age. But 
the exceptionally acute stem-leaves and the sharply rellexed peduncles 
after dowering confirm the identification. 
2. Bo unmuller, pi. exs. Anatoliae orient., a. 1889, no. 708, from 
Atnasia “in collims graminosis planitiei Gfeldinghiaiy alt. 400 m. 
15 v,” determined bv Haussknecht as O. hebebulbum DC. has no 
resemblance to that species, “ calyce albo-villosissimo,” founded on 
Aueher-Eloy, Nos. 2314 and 2389, Mesopotamian plants, of which 
no. 2314 may be seen in herb. Kew. Bornmuller’s plant, like hebe- 
bulbum , shows a passage from Boissier’s § Asterotricha to his § llete- 
rotricha, only the very uppermost leaves and the bracts being with¬ 
out stellate hairs at the base of the bristles, whilst these are present 
on all the rest of the plant. It is only on this ground and on account 
-of the less blunt leaves that it can be distinguished from the other 
less hispid forms of O. pallidum Boiss., such as var. olympicwrii 
Bornm. (1899) No. 5309, as to which see below. It is probable that 
Boissier would have referred this plant to his “ O. stellulatum var. 
cjenuinum ,” with synonym O. lielveticum Boiss., of FI. Or. iv. p. 201, 
which of course is neither O. stellulatum W. K. nor the O. lielveti¬ 
cum Boiss. of Switzerland and northern Italy. 
I have not been able to discover that this form has been discussed 
elsewhere, or had any name given to it, and I therefore propose to call 
it Onosma ambigens mihi; Asterotricha et Heterotricha ambigens, 
formis mitioribus O. pallidi Boiss. proximum, et vix distinguendum 
nisi setis foliorum supremorum basi non stelligeris; ab O. taurico et 
a sequente corollis minute puberulis differt; ab O. hebebulbo capi- 
tulis pilosis, sed minima “ albo-villosissimis ” aut “ albo-hispidissimis,” 
habitu et patria longius distat. 
3. Bornmuller, pi. exs. Anatolire orient., a. 1889, No. 709, 
also from Amasia : “in apricis saxosis alt. 4-000 m. 27 v,” and 
no. 709 c “in apricis alt. 4-500 m. 14 v,” respectively determined by 
Haussknecht as “ O. stellulatum W. K. (Boiss. FI. Or.) forma 
strictior” and “forma minor.” Here, again, the specimens are not
