24 Dr. Hancock on the Angustura Bark Tree. 



rest ; whereas the corolla is irregular, there being two longer 

 and three shorter petals. 



Fifthly. The appendages which I had considered as nectaria, 

 by others taken for abortive stamina, are invariably five in 

 number, though stated by some as three (Rceiner), and by others 

 as four (Kunth). 



Sixthly. The stamina are said by Kunth to be monadelphous, 

 whereas they are distinctly (separately) inserted in the two longer 

 petals of the corolla. Their number is also greatly at variance 

 with the truth, the Plants? JEquinoct tales and most other works 

 terming it a Pentandrous Plant. But it may be said that those 

 linear leaflets, which I have considered as nectaria, have been 

 reckoned amongst the stamina as being nearly concentric with 

 them. This, we see, has been done, but it does not clear the 

 difficulty, for these bodies are, in Orayuri, invariably Jive in 

 number, and, having no anthers, ought not to be confounded 

 with the stamina, whilst the proper filaments with large anthers 

 pass at the same time totally unnoticed ; but even supposing the 

 numbers to correspond, these linear leaflets could never with 

 propriety be regarded as stamina, as the anther is the essential 

 part, and without the anther there is no stamen. If these are 

 to be taken for stamens, then the plant is heptandrous. In the 

 description given in the Plantce JEquinoctiales there is, more- 

 over, no mention of sterile stamens, 



Seventhly. The seeds are represented as being solitary, where- 

 as, though one of them is generally abortive, there are inva- 

 riably two, or, at least in the case of abortion, the rudiments 

 of a second. 



In the Orayuri, I can find no trace of the spur at the bottom 

 of the anthers mentioned by Humboldt. 



The pistil of BonplandiA is said to have 5 stigmata, in- 

 stead of a simply capitate one. 



There are other minor discrepancies in the flower, but the 

 most remarkable appearance in Orayuri, and which is not touch- 

 ed upon in the description of Bonplandia, is the uncommonly 

 strong and horny arillus in which the seeds are enclosed. This
