PRIMROSE. 67 
only open-in bright weather. Note the 4-angled stems, oppo- 
site entire leaves, and solitary flowers, in which the corolla- 
lobes are divided nearly to the base. The fruit is a capsule, 
which dehisces transversely (see p. 56). 
Compare with this type the Red Mapau (Myrsine wrvillet), 
a common tree in many parts of the country. The flowers are 
very small, and crowded into little irregular clusters (fas- 
cicles*). The calyx is 4- or 5-lobed, and the corolla formed 
of 4 or 5 nearly free petals, each with a stamen adnate to it. 
The ovary is 1-celled, and is wholly filled up by a free, thick, 
and somewhat fleshy placenta, in which 1, or rarely 2 or 8, 
ovules are imbedded. The fruit is a roundish black berry, 
containing one seed, as, even if more than one ovule be present 
in the ovary, all but one are arrested in their development. 
On making a longitudinal section of the seed (which has a 
rather hard testa), the embryo is seen lying transversely 
across the albumen. 
17, Foraer-mz-nor (Myosotis palustris). 
We may take this as our next type, because it is commonly 
found in gardens. Some of the New Zealand species of 
Myosotis are very handsome plants, but they are not readily 
accessible. 
Note the rough hairy character of the plant. The flowers 
are arranged in an inflorescence called a scorpioid cyme. 
It is theoretically a cyme in which only one lateral branch is 
developed at each node, giving the general appearance of a 
coiled-up raceme.
