CCXIV.— ANALYTICAL DRAWINGS OF THE 
PRIMROSE ORDER. 
(Primulales.) 
D IFFERING much in size, colour, and general form, the plants analysed in 
the first six rows of figures on this Plate are all closely related in most 
fundamentals of anatomy, so that there can be no question as to their belonging to 
one Family ; while those represented in the two remaining rows of figures, though 
still more closely allied to one another, can be recognised as not remotely connected 
with the rest. As in the Order Ericales we saw in the porous dehiscence of the 
anthers a link uniting all the examples, so here the pentamerous flower with a single 
stamen in front of each petal is a character common to all. The most obvious 
distinction separating the Family Primulace<c — the first six rows of figures — from 
the Plumb aginacetc— the last two rows — is the single style in the former and the five 
distinct styles in the latter group. 
The first six rows only represent four genera, the first two being devoted to 
Primula and the fifth and sixth to Anagallis. 
In the first line, the Cowslip ( Primula veris Linn6), Fig. i is a single flower, 
apparently of the short-styled form, seen laterally, and of natural size ; Fig. 2, the 
same seen from above ; and Fig. 3, the same with half the calyx removed, showing 
the space between the calyx and corolla which serves as a protection for the honey 
in the corolla-tube against boring insects. Fig. 4, a longitudinal section of the 
corolla, shows the relative position in this form of the stigma — half-way down the 
corolla-tube— and of the anthers near its mouth, the orange spots being honey- 
guides ; and Fig. 5, an enlarged longitudinal section of the ovary, shows the ovules 
attached to the globose free-central placenta. 
The second line of figures illustrates both forms of the Primrose ( Primula 
vulgaris Hudson). Fig. 1 is a flower of the long-styled or pin-eyed form, seen from 
above ; Fig. 2, the corolla of the same, seen laterally ; Fig. 3, the calyx ; Fig. 4, a 
longitudinal section of the same, showing the epipetalous anthers half-way down the 
corolla-tube and the stigma at its mouth ; Fig. 5, a similar section through a short- 
styled flower, showing the relative positions of anthers and stigma reversed ; Fig. 6, 
a stamen ; Fig. 7, the gynaeceum ; and Fig. 8, the placenta, covered with ovules. 
These eight figures are of natural size. Fig. 9 is a capsule bearing withered 
remains of the flower, enlarged; and Fig. 10 is a view of the colourless placenta 
and green ovules removed from it. 
The third line of figures illustrates the Water Violet ( Hottonia palustris Linne), 
Fig. 1 showing a petal, enlarged, with the superposed stamen in front of it ; Fig. 2, 
a longitudinal section to show the form of the corolla-tube and the insertion of the 
stamens in the short-styled form ; Fig. 3, the calyx, style, and stigma, natural size ;
