THE GOURD FAMILY 383 
135. The mint family (Labiate). Examples: sage 
(Figs. 132, 133, page 138), thyme (Fig. 134, page 139), 
spearmint (Fig. 135, page 139), summer savory (Fig. 136, 
page 139), sweet marjoram (Fig. 137, page 140), and pepper- 
mint (Figs. 146 I, II, pages 147, 148). 
~The formulas of Mentha, Thymus, Origanum, Satureia, Salvia, 
and Labiate are given on pages 418, 419. 
When a gamopetalous corolla has the two upper petals 
coalescing with one another more completely than they do 
with those at the side, and the two lateral ones in turn more 
completely coalescing with the lower petal, there results a 
two-lipped or labiate : form shown especially well in Salvia 
and most other members of the family. It should be noted, 
however, that more or less labiate corollas occur also in many 
genera of the figwort family and some other families of the 
group we are now studying. Typical members of the mint 
family are easily recognized as sguare-stemmed, aromatic herbs 
with opposite leaves, labiate corolla and schizocarpic fruit of 
four nutlets. Asin the figwort family the juice is watery, the 
leaves exstipulate, the petals imbricate, and the stamens generally 
four, but the seeds are exalbuminous and the embryo uncoiled. 
136. Phlox order (Polemoniales or.Tubiflore), embraces a 
number of families besides the four just mentioned. In 
general they are characterized by having perfect, regular or 
irregular, gamopetalous flowers, with two to five stamens ad- 
herent to the corolla, and distinct; the anthers seldom poricidal; 
the ovary compound and superior. 
For the formula of Polemoniales see pages 418, 419. 
137. The gourd family (Cucurbitaceze). Examples: pump- 
kin (Figs. 80 I-81 I, pages 76-78), squashes (Figs. 81 II- 
84, pages 79-82), cucumber (Figs. 85-87, pages 82, 83), 
muskmelon (Figs. 102, 103, page 95), watermelon (Figs. 
104, 105, page 96), sponge cucumber (Fig. 225, page 240), 
aiid bottle-gourd (Fig. 265, page 275). 
See pages 418, 419 for the formulas of Cucurbita, Cucumis, 
Citrullus, Lagenaria, Luffa, and Cucurbitacez.
