peculiar form, the cells elongating very much perpendicularly to the 

 surface (the same occurs at five points above the border in Apocynum). 

 Immediately beneath these five places five points remain without ac- 

 quiring a perfect epidermis, while five cords of conducting tissue are 

 formed from them into the canal of the style, in the same way as in the 



K0 A, 23, C, Asclepias syriaca. A, Completely expanded flower : a, sepals ; b, petals ; 

 c, stamens. J?, The same seen from above : a, hood-like appendages on the back of the 

 anther ; b, wing-like appendages of the anther, which, retracted, form a kind of little 

 box ; d, crest-like elongation of the anther, which lies fast upon the stigmatic body (/) ; 

 e, gland-like bodies, which, five in number, alternate with the five stamens, and adhere 

 to the epidermis of the stigmatic body. C, Part of the organs of propagation from a 

 very small bud : a, hood ; b, spur projecting from it ; c, e,f, as before. 



!i D, E, F. Gomphocarpus fruticosus A, Longitudinal section through the organs 

 of propagation of a very young bud : the section goes between the two germens, and 

 on the right side between two stamens, and divides in half the stigmatic body above a 

 stamen on the left, and on the right the tubes formed by the confluent filaments, 

 a, Germen ; b, style ; c, half the stigmatic body ; d, filament of the divided stamen ; 

 e, vascular bundle of the same ; /, half an anther ; g, divided staminal tube ; /<, wing- 

 like appendage of the anther, so far as it forms the box-like body; i, half the gland-like 

 body lying in the dense epidermis, which is remarkably thickened below it, and appear- 

 ing as an immediate prolongation upward of the wing-like appendage of the anther. 

 E, The pistil extracted free : a, two germens ; b, two styles ; c, a stigmatic body, on 

 which three gland-like bodies are visible. F, Gland-like bodies (a), with the three 

 arms (6) and the pollen-masses (r) appended to them, from a perfectly developed 

 flower.
