tion of these insects, but they would probably yield to 
the methods employed against the Onion Fly (which 
see). Of course, sickly plants ought to be removed from 
among the others without delay. Dr. Bos recommends, 
as most successful, to keep all bulbs of Narcissus under 
water for eight days before planting, as this treatment, 
while not injuring the bulb, will kill the larve, which, 
at the usual season of planting out (August), are still 
near the upper part, and have not done much damage.

NARDOSTACHYS (from nardos, a sweet-scented 
‘shrub, and stachys, a spike; the Nardus of the ancients 
was close akin to this plant, and not connected with the 
modest grass of that name). ORD. Valerianee. This 
genus comprises a couple of species of hardy perennial 
herbs, natives of the Himalayas. Corolla red or purplish ; 
cymes at the apices of the branches or stems, scape- 
formed, dense, sub-capitate. Leaves entire, radical ones 
elongated, stem ones few. Root short, thick, fibrous, 
very fragrant. The species introduced is N. Jatamansi, 
which, according to Dr. Royle, is the Spikenard of the 
ancients. 
N. Jatamansi (Jatamansi). f. in dense small heads, arranged 
in a trichotomously-branched terminal panicle ; corolla pale rose- 
purple, cylindric, gibbous at base, and contracted into a very 
short, narrow tube; lobes rounded, dorsal one larger; scape din.

elliptic-lanceolate or spathulate, acute; nerves obscure, narrow

upwards in a simple or forked ascending stock, lin. to Sin. long, 
densely clothed with the black fibrous remains of the old 
petioles. 1878. (B. M. 6564.)

Abama. ORD. Liliaceew. A small genus (four species) 
of hardy, herbaceous, rush-like, marsh plants, inhabiting 
the temperate regions of the Northern hemisphere. Peri- 
anth of six equal, linear, membranous-herbaceous seg- 
ments, which are yellow, green at back. Leaves 
distichous at base of stem, equitant, linear, often falcate, 
rigid, striated. The undermentioned species are well 
worth naturalising in boggy situations. Propagated by 
divisions of the root, or by seeds.
