146 CLASS-BOOK OF BOTANY. 
Order LIl. Boracinez. 
Herbs, usually hispid (rarely glabrous); leaves alternate, 
quite entire, exstipulate, often strongly nerved. Flowers 
usually produced in scorpioid cymes. Calyx 5-lobed or -par- 
tite, valyate in bud. Corolla regular, frequently rotate, 
5-lobed, lobes imbricate in bud, throat often closed with 
scales. Stamens 5, epipetalous, filaments usually short, 
anthers 2-celled. Carpels 2, each 2-lobed to the base and 
2-celled; ovule 1, pendulous in each cell; style gynobasic. 
Fruit of 4 indehiscent 1-seeded nucules; seed with straight 
embryo, foliaceous cotyledons, superior radicle, and little or 
no endosperm. (Pp. 67-68, figs. 121-123.) 
The order is a large one, and of wide distribution. It includes 68 
genera and about 1,200 species, of which 2 genera, represented by 15 or 16 
species, occur in New Zealand. Of these, Myosotis (Forget-me-nots), with 
14 species, is a widely-spread genus; but 12 of our species are endemic, 
1 ranges into South America, and 1 into Australia. Myosotidium is a 
singular genus, represented by only 1 species—M. nobile (Chatham Island 
Lily), which is only found in the Chatham Islands. It is allied to the 
widely-spread genus Cynoglossum, or Hound’s-tongue, which, however, 
does not occur in this colony. 
There are very few plants of any economic importance in the order. 
Some genera (besides those named above) are cultivated for the sake of 
their flowers—e.g., Heliotropiwm, Borago (Borage), Cerinthe, &c. 
Order LVI. ScropHuLARINEs. 
Herbs or shrubs, rarely trees; leaves opposite or alter- 
nate, exstipulate. Flowers usually irregular; pedicels with 1 
or 2 axillary bracteoles. Calyx 3—5-partite, inferior, usually 
persistent. Corolla 4—5-lobed, often 2-lipped; lobes imbricate 
in bud. Stamens 2, or 4 and didynamous, sometimes with a 
rudimentary fifth; anthers 1- or 2-celled. Ovary 2-celled ; 
style simple; stigma capitate or 2-lobed; ovules numerous in 
each cell. Fruit a capsule, dehiscing variously; seeds small, 
with straight embryo in fleshy endosperm. (Pp. 69-72, figs. 
126-133.) 
A large and natural order of wide distribution, including nearly 160 
genera and 1,900 species. In this country there are 9 genera, with about 
70 species, this latter number varying with the number of species of Veronica 
which are accepted. Calccolaria has two species, both endemic; the genus 
is mainly South American. Mimulus, 2 sp., of which MW. repens ranges 
into Australia. Mazus pumilio and Gratiola, 2 sp., have the same distri- 
bution. Glossostigma elatinoides is endemic, while Limosella aquatica is 
found in all temperate regions. Veronica is one of the most character- 
istic genera of New Zealand, as in no other part of the world does it reach 
such remarkable development as it does here, the majority of the local 
species being shrubs, often of large size. With the exception of V. ellip- 
tica, which also occurs in the southern part of South America, and V. 
anagallis, which is widely distributed, all the rest are endemic species. 
Their number is variously estimated between 40 and 60, or even more, by 
different botanists ; but the various species tend to pass more or less into 
one another, The extreme forms differ most remarkably from each other 
in habit and appearance. Ourisia, an Antarctic genus, is represented by
