BOTANY. 117 
Pedicularis palustris, Lousewort (Europe) (pl. 60, 61, fig. 15); a, upper 
part of the plant; b, root; c, lower lip of the corolla; d, section of the corolla 
with the stamens; e, pistil. 
Veronica officinalis, Speedwell (central Europe) (pl. 60, 61, fig. 14). 
Orper 87. Oropancuez, the Broom-rape Family. Calyx divided, per- 
sistent, inferior. Corolla monopetalous, hypogynous, irregular, usually bilabi- 
ate, persistent; sestivation imbricated. Stamens four, didynamous. Disk 
fleshy. Ovary free, one-celled, composed of two carpels which stand fore and 
aft, with two or more parietal placentas ; ovules 00; style one; stigma two- 
lobed, each of the lobes belong half to each carpel. Fruit capsular, inclosed 
within the withered corolla, one-celled, two-valved. Seeds 00, minute ; em- 
bryo very minute, at one end of fleshy albumen. Herbaceous parasitical — 
plants, having scales in place of leaves. They are natives of Europe, more 
especially the southern parts, and of Asia, North America, and the Cape of 
Good Hope. Lindley gives twelve genera, and 116 species. Examples: 
Orobanche, Lathreea, Epiphegus, Conopholis, Aphyllon. 
The plants of this order are generally destitute of green foliage, with lurid 
yellowish or brownish scales instead. They are mostly parasitic on the roots 
of various other species. 
Lathreea squamaria (Europe) (pl. 60, 61, fig. 16); upper and lower part of 
the plant; @ and b, calyx; c, corolla; d, anthers; e, pistil; f{ pericarp, 
&e. 
OrveR 88. Sotanaces#, the Nightshade Family. Calyx inferior, five-, 
rarely four-partite, persistent. Corolla monopetalous, hypogynous, with the 
limb five-, rarely four-cleft, regular, or somewhat unequal, deciduous; sestiva- 
tion plicate or imbricated. Stamens inserted on the corolla, equal in number 
to the corolline sehments, and alternate with them; anthers with longitu- 
dinal or porous dehiscence. Ovary usually two-celled, sometimes four-, 
five-, or many-celled; ovules indefinite; style continuous; stigma simple. 
Fruit with two, four, or more cells, rarely unilocular; either a capsule 
delhiscing in a septicidal or circumscissile manner, and haying a double 
dissepiment parallel to the valves, or a berry with the placentas adhering 
to the dissepiment, or a nuculanium with five or more nucules. Seeds 00; 
embryo straight or curved, often excentric, lying in fleshy albumen; radi- 
cle next the hilum. JHerbs or shrubs, with alternate leaves. Natives 
of most parts of the world, but abundant in the tropics. The order 
has been divided into two sections, which are not, however, well de- 
fined. 
A. Curvembryec. 
(Embryo curved, with semi-cylindrical cotyledons.) 
Tribe 1. Nicotiane. Capsule bilocular, separating into two valves by septi- 
cidal dehiscence. Examples: Nicotiana, Petunia. 
Tribe 2. Datureew. Capsule or berry incompletely four-locular. Example: 
Datura. 
Tribe 3. Hyoscyamee. Capsule bilocular, opening by a circular slit. 
Example: Hycscyamus.
