because as far as I can discover it 

 produces hermaphrodite and fe- 

 male flower-heads, but not cleis- 

 togamic flowers. Krascheninikowia 

 (vel Stellaria) has been omitted 

 because it seems very doubtful 

 from Maximowicz' description 

 whether the lower flowers which 

 have no petals or very small ones, 

 and barren stamens or none, are 

 cleistogamic ; the upper herma- 

 phrodite flowers are said never to 

 produce fruit, and therefore pro- 

 bably act as males. Moreover in 

 Stellaria graminea, as Babington 

 remarks ('British Botany,' 1851, 

 p. 51), " shorter and longer petals 

 accompany an imperfection of the 

 stamens or germen." 



I have added to the list the fol- 

 lowing cases : Several Acanthaceae, 

 for which see J. Scott in ' Journal 

 of Bot.' (London), new series, vol. 

 i., 1872, p. 161. With respect to 

 Salvia see Dr. Ascherson in ' Bot. 

 Zeitung,' 1871, p. 555. For Oxy- 



baphus and Nyctaginia see Asa 

 Gray in 'American Naturalist/ 

 Nov. 1873, p. 692. From Dr. 

 Torrey's account of Hottonia in- 

 fiata ('Bull, of Torrey Botan. 

 Club,' vol. ii. June, 1871) it is 

 manifest that this plant produces 

 true cleistogamic flowers. For 

 Pavonia see Bouche in ' Sitzungs- 

 berichte d. Gesellsch. Natur. 

 Freunde,' Oct. 20, 1874, p. 90. I 

 have added Thelymitra, as from 

 the account given by Mr. Fitzger- 

 ald in his magnificent work on 

 1 Australian Orchids ' it appears 

 that the flowers of this plant in its 

 native home never open, but they 

 do not appear to be reduced in 

 size. Nor is this the case with 

 the flowers of certain species of 

 Epidendron, Cattleya. &c (see 

 second edition of my ' Fertilisation 

 of Orchids,' p. 147), which with- 

 out expanding produce capsules. 

 It is therefore doubtful whether 

 these Orchideae ought to have been
