have no petals or very small ones, 

 and barren stamens or none, are 

 oleistogtimio ; the upper herma- 

 plirodite flowers are said never to 

 produce fruit, and therefore pro- 

 bably act as males. Moreover in 

 Stellaria graminea, as Babinjtton 

 remarlts (' 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- 

 io wing cases : Several Aoanthacese, 

 for which see J. Scott in 'Journal 

 of But.' (London), new aeries, vol. 

 i. 1872, p. 161. With respect to 

 Salvia see Dr. Ascherson in ' Bot. 

 Zeitung,' 1871, p. 555. _ Tor Oxy- 

 baphus and Nyctaginia see Asa 

 Gray in ' American Naturalist,' 

 Nov. 1873, p. 692. From Dr. 

 Torrey's account of Hottonia 

 inflata ('Bull, of Torrey Botan. 

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

 manifest that this plant produces 

 true cleistogamio ilowers. Fur 



Pavonia see Bouohe in ' Sitzungs- 

 berichte d. Gesellsch. Natur. 

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

 have added T 1 1 ely mi tra,as from the 

 account given by Mr. Fitzgerald in 

 his magnificent woi-k on ' Austra- 

 lian Orchids ' it appeal's 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, &o. 'see second edition 

 of my 'Fertilisation of Orchids,' 

 p. 147), which without expanding 

 produce capsules. It is therefore 

 doubtful whether these Orchidese 

 ought to have been included in the 

 list. From what Duval-Jouve says 

 about Cryptostachys in 'Bull. 

 Soc. Bot. de Prance,' tom. x. 1863, 

 p. 195, this plant appears to pro- 

 duce oleistogamic flowers. The 

 other additions to the list are 

 noticed in my text.
