AM ARYLLIDACEA2. 
point ; filaments short, equal, inserted in the opercle, 
free ; anthers erect, affixed at the base, apiculate ; 
orifices terminal, round ; capsule valveless ; seeds 
whitish; pollen very minute. 
1. Nivalis. — Engl. hot. 1. 19. Sepals white; petals 
with 5 green lines down the inside of each lobe, 
and an undulated green mark towards the top out- 
side. 
Var. horte?isis, flore semipleno. The doubleness of this 
flower consists in a multiplication of the scale-like 
petals, on some of which an anther more or less 
perfect is usually borne ; which is very usual also 
in Camellia Japonica. Dr. Lindley considers this 
analagous to the production of supernumerary 
anthers in Gethyllis, which occurs also in Vellosia. 
It appears to be the necessary result of the imper- 
fect conversion of the stamens into petals, the flower 
being in fact only semi-double. The like occurs in 
the semi-double Hippeastrum equestre. In Ge- 
thyllis and Vellosia the stamens are multiplied 
without any multiplication of the segments. 
2. Plicatus. — Bot. Reg. 7. 545. Bot. Mag. 47. 2162. 
Marsh v. Bieberstein. Fl.Cauc. Sup. 225. Leucojum 
bulb, praec. Byz. Clus. Hist. 1. 169. Bulb larger ; 
leaves larger, with their margins folded back ; scape 
more robust ; flower smaller, green, more intense; 
petals set more in than the sepals, and having more 
the appearance of a scale. The sepals are a con- 
tinuation of the outer coat of the germen, but 
in plicatum the petals are set on its inner coat, and 
their base does not range with the sepals. If 
the petals of Nivalis had agreed with it in that 
respect, I should have thought that the true petals 
were entirely deficient. It is a native of Russia 
and Asia. 
81. Erinosma. — Bulb ovate; leaves linear lorate ; scape 
1-2-flowered, pedunculated; germen triangular, obo- 
vate, pendulous ; spathe tubular below, above slit 
on one side, transparent on the other ; germen obo- 
vate, segments of the perianth separate, similar ; fila- 
ments short, equal, free, erect, inserted in the opercle ; 
anthers erect, affixed at the base, not apiculate ;
