366 MR. C. C. LACAITA : A REVISION OF 
5. Herb. Mus. Paris, including the collections of Tournefort, Lamarck, 
Jussieu, and de Coiney. I had not time to go through the speci- 
mens of herb, Cosson, now at the Museum, which are indispensable 
for Algerian species. 
. Herb. Bonaparte which includes herb. Rouy. 
. Erbario Centrale Italiano at Florence, and Desfontaines's specimens 
in herb. Webb. 
. The herbarium of the University of Rome. 
. Tenore's and Gussone’s herbaria at Naples.

I have been sent a few specimens through the kindness of M. Sudre of 
Toulouse, Prof. Coutinho of Lisbon, and Prof. Henriques of Coimbra. To 
these gentlemen I must express my gratitude, and above all to M. Henri 
Lecomte and his assistants at the Paris Museum, and to Prince Roland 
Bonaparte, who so generously allows access to his magnificent collections. 
My thanks are also due to many in Italy and at home, particularly to 
Dr. Daydon Jackson, whom I have troubled with endless small inquiries, 
and to Mr. Wilmott at the British Museum for the assistance of his younger 
eyes and for counsel, perhaps not always followed, as to technicalities of 
nomenclature. 
L 
FIVE CRITICAL SPECIES OF ECHIUM. 
ECHIUM JUDÆUM, sp. nov. 
Among the specimens of Fehium from Palestine in the herbaria of the 
British Museum and Kew are several labelled plantagineum (or violaceum in 
the same sense), although differing altogether from that species in their 
indumentum, which is not homogeneous but dimorphous, in the shape of the 
bracts, and in the corollas which are more obliquely cut, but less wide at 
the throat, and covered with soft pubescence instead of being glabrous with 
only some long hairs on the veins and ciliæ on the margin. In fact, the 
nearest species is not E. plantagineum but E. grandiflorum, Desf., to which 
E. judeum bears a considerable resemblance, but the filaments are glabrous, 
at any rate, as seen without the microscope, whereas in grandiflorum they 
are constantly furnished with scattered transparent hairs, longer than the 
breadth of the filament itself. 
E. judeum, mihi; Sect. Fleutherolepis, Coincy. 
Radix fusiformis, ille Æ. vulgaris similis. Caules plerumque simplices, 
erecti, c. 35 em. alti, indumento dimorpho, se. pubescentia creberrima, 
brevi, grisea, et pilis longioribus, sparsis, albis, substrigosis. Folia 
radicalia (in exempl. unico ex Hierosolyma presentia) petiolata, ovalia, 
medio nee basi latiora, 14 x 41 em. ; penninervia, nervis utrinque 6-8
