REPORT ON THE PLANTS COLLECTED BY MR. WEIR. 179 
XXXVIII.—REPORT ON THE PLANTS COLLECTED 
BY MR. WEIR, ESPECIALLY THE BIGNONIACE. 
By Јонх Miers, Esq, F.R.S., F.L.S., &e. 
same time the more essential details of their floral and carpological 
structure, with the design of determining generic characters, and de- 
fining their limits, so that they might form the groundwork for mono- 
graphs of the different genera in succession. With this view I pub- 
lished in the Annals of Natural History for March, 1861, some pre- 
liminary remarks on the general structure of the order, especially that 
of the ovary and the peculiar mode of its carpellary development, as 
this seemed to form the most reliable basis for the division of the family. 
This was subsequently followed by descriptions of Adenocalymna and 
T'anacium, the unusual structure of the fruit and seeds in these genera 
being previously unknown : it was there shown, that the latter genus 
belongs to Ше Eubignonicez, and is closely allied to the former, and 
that it has no relation with Crescentia, near which it had been placed 
by botanists. At this point, my plan was arrested by the knowledge 
that Dr. Seemann, who had given a synopsis of the Crescentie in the 
Linnean Transactions, was engaged in the investigation of the Bigno- 
тасее, and in deference to him I suspended further progress, maintaining 
however my right to resume the subject whenever circumstances should 
induce me to do so. І therefore now proceed to enumerate Mr. Weir's 
Bignoniaceous plants, and to make several observations in connexion 
with them. 
1. ADENOCALYMNA NITIDUM, Mart. D.C. Prodr. ix. 200; Miers, 
Ann. Nat. Hist. 8 Ser. vii. 391; Contrib. Bot. ii. 76. San 
Paólo, Brazil (Weir, No. 31). 
2, ADENOCALYMNA LONGERACEMOSUM, Mart. D.C. Le. 201; 
Bignonia 3-foliolata, Vell. Flor. Flum. 945. уі. tab. 16. 
San Paolo, Brazil (Weir, No. 5).
