ACADEMIC BOTANY. 



(1) confluence (the ninning together of the two cells), as in the Gam- 

 boge (Fig. 169, c) and Marsh-Mallow, or through 

 (2) obliteration (the entire disappearance . of one 

 cell), as in the Canna, or through (3) separation, in 

 which the two cells are separated by a long, trans- 

 veree connective, as in the Sage (Fig. 168, D), the 

 anther being Dimidiate (L. cut in half). The an- 

 ther of the Mistletoe (Fig. 65, B) is many-celled 

 (pluriloeular), and opening by pores. 



265. The Forms are as variable as those of leaves ; 

 the descriptive terms are nearly the same. The 

 Oleander anther is Sagittate (Pig. 168, A) ; that of 

 the Cucumber Is Flexuose (Fig. 168, C). 



266. The Appendages are also innumerable. The 

 TkT iTl.^ollinia (^l^finder connective has a long ciliate plume (Fig. 



of OrchU. Morio at- 168, A); the filament of the Humirium has glan- 

 tached to the reti- dular teeth (Fig. 168, E). The Milkweed (Fig. 172, 

 So?"een.' «) has a lovely hood and horn. 



267. The Dehiscence, or opening, of the anther- 

 lobes is : (1) Circum- 

 scissile (L. cut 

 around) ; here the 

 lobes are cut trans- 

 versely, the upper 

 part serving for a 

 lid, as in the Gam- 

 boge (Fig. 169, c) 

 and the Pyxidan- 

 thera, or Box-anther 

 (Gr. pyxidion, little 

 box), which gets its 

 botanical name from 

 this character. (2) 



Lotyitudmal ; here j.,g 172.— A, fl. of Milkweed {Aeclepias hiberom). B, 

 each cell is marked separate stamen, with its appendages (horn and hood). 0, 

 with a longitudinal gynceoium, with pollinia adherent to the stigma. D, two

which it opens, as in 

 the Hepatica (Fig. 168, 

 G), the Oleander (Fig. 

 168, A), the Grasses 

 and Lilies; it is the 

 commonest mode. (3) 

 Porous; here the Su- 

 tures remain closed, 

 and each cell opens by 

 a pore at the top, as in 

 the Whortleberry (Fig. 

 168, F) and the Poran- 

 Fis. 173.— A, Anther of Squash (Oucurbila Pepo), with thera • (Fig. 168, B), 

 two pollen-mothers. B, ripe pollen-mother, with pollen- which gets Its name 

 grain escaping. from this character. 



The pores of the Mistletoe anther perforate it in every part (Fig. 66,
