SOME CRITICAL SPECIES OF ECHIUM. 393 
alphabet, as the use of numbers might lead to confusion should the sheets 
themselves be numbered at some future time :— 
(L) LonosrEMON"*. 
l. Echium argenteum, L. Mant., p. 202, non Lobostemon argenteus, 
Buek in Linnæa, x. p. 133. This is specimen O in the herbarium, 
labelled Æ. argenteum. It has been examined by Mr. N. E. Brown, 
who confirms that it is not the L. argenteus of Buek, but a 
species not otherwise known, which he has described and named 
Lobostemon magnisepalum in a paper read before the Linnean 
Society on 6 February, 1919, which will appear later in this 
Journal. The herbarium contains no specimen corresponding 
to ££. argenteus, Buek. 
2. Echium capitatum, L. Mant., p. 42— Lobostemon capitatus, Buek, 
l.c. p. 143. Specimen Q. 
3. Echium fruticosum, L. Sp. Pl. (1753) p. 139 = Lobostemon 
fruticosus, Buek, l. c. p. 134. Specimens RID,

levigatus, Buek, l. c. p. 139. Specimens U, V. 
Echium spicatus, L. fil., Suppl. p. 132— Lobostemon spicatus, Buek, 
l.c. p. 145. Specimen W. 
6. Echium, unnamed = Lobostemon montanus, Buek, l.c. p. 152, on 
the authority of Mr. N. E. Brown. Specimen P.

(I1.) MEGACARYON. 
The herbarium contains no specimen of Echium orientale, Sp. Pl. p. 139, 
and it is practically certain that Linnæus never saw the plant in any form. 
Its identity depends entirely on the synonym quoted from Tournefort, 
« Echium orientale, verbasci folio, flore maximo campanulato,” and that 
author's account of it in his * Voyage au Levant,’ ii. p. 248 (1717), or iii. 
p. 83, in the English translation of 1741. It is first mentioned by Linnzeus 
in Hort. Cliff. p. 43, “ Echium caule ramoso, foliis caulinis ovatis, floribus 
solitarüs ex alis. Tourn. Cor. 6; itin. 3, p. 94. Crescit in Oriente." The 
diagnosis in Sp. Pl. is a mere transcript of this with the word “lateralibus ”? 
substituted for “ex alis." Tournefort found his plant at Grezi on the road 
from Trebizond toward Armenia. His description and the locality make it 
certain that it is the species for which Boissier created his monotypic genus 
* I have not included in the Lobostemon list an Echium glabrum, Linn., Epist. ed. van 
Hall, p. 27 (1880), where that name is given in a letter to J. Burman, of Oct. 4th, 1758, 
for a plant received from him. The diagnosis runs, “Æ. glabrum, caule levi, foliis lanceo- 
latis nudis, margine carina apiceque scabris,” with synonyms cf Pluk., Old., and Herm. On 
the strength of these synonyms, Richter, Cod. Linn. p. 156, identifies this plant with 
E. levigatum, published two years after this letter was written. E. glabrum, Vahl, and 
E. glabrum, Thunb., are of course much earlier than this Æ. glabrum, Linn., of 1830,
