120 Dr. Strethill Wright's Observations on 



dio curtius, rectum, anantherum; antherse per paria approxi- 

 mate, lobi lineares, obtusi, segregati, divaricatissimi, connective 

 apicali obtuso breviter excurrente; ovarium conico-oblongum, 

 glabrum, disco latiusculo carnoso impositum ; stylus subtenuis, 

 5 poll. long. ; stigmatis laniellse cuneato-oblongse, rotundatse, 

 3 lin. long., glabra?; fructus vix notus, oblongus, verisimiliter 

 ei T. albiflorce consimilis, ut dixit cl. Plum. (loc. cit.), " capsulam 

 vulgi reprsesentat, quam Tobacco replent, secumque portant." 



With this will cease, for the present, my communications on 

 the Bignoniacece, as I learn from Dr. Seemann that he has re- 

 sumed his inquiries into that family, and is about to publish the 

 results of his investigations. The respect I have for that zealous 

 botanist, together with the desire on my part to avoid contra- 

 vention, and the knowledge that he has long studied the subject, 

 induce me to cede to him the priority. As he has the advantage 

 of consulting collections to which I have no means of access, 

 more may be anticipated from his exertions. I reserve to my- 

 self, however, the right of resuming the subject at a future time, 

 and of carrying out my original plan of denning the limits of the 

 genera and subgenera I have sought to establish upon features 

 hitherto unobserved, and also of illustrating their characters by 

 drawings of one or more species of each group, accompanied by 

 analytical figures of the flower, fruit, and seed.

On the Reproduction of Ophryodendron *. 



Ophryodendron abietinum, which I have figured in various atti- 

 tudes in PI. III., has been noticed elsewhere by Claparede and 

 Lachmannf and myself J, several years since; but it was not 

 until the spring of the present year that I was able to discover 

 its mode of reproduction. The animal presents the appearance 

 of an oblong sac filled with homogeneous and finely molecular 

 matter, and is found attached to the corallum of Sertularia 

 pumila. From one end of the body or sac arises a proboscis, 

 generally appearing as a short and closely-wrinkled club, but
