the many open flowers were thickly fertilized, as though each 

 flower had been constantly visited. 



In both the Bedford species and Saundersice the nectary pro- 

 jects forwards, whilst in sjpeciosa it is projected vertically down- 

 wards, and in Boltoni it is curved inwards (? slightly). 



In all, the position of the nectary appears to lie in a plane 

 drawn from the enclosed pollinia downwards. 



The hood of the rostellum in 8aundersi(jd presents a marked 

 contrast to the Bedford species in its diminished and almost rudi- 

 mentary condition. 



These notes, I fear, are very imperfect, owing to the scanty 

 drawings I have had an opportunity of examining, and I regret 

 that I am uttei'ly unaccjuainted with Bonatea gracilis, Lindl. 



If the species here noted has not as yet been described, I pro- 

 pose the specific name of Dariainn, in honour of. the naturalist 

 from whose works I have derived so much incitement to prosecute 

 the study of living beings. 



Notes on Jussicea. By Mr. Charles "Wright. Communicated 



by Dr. Hooker. 



[Eead May 7, 1868.] 



I ^'EVER so much appreciated the value of seeds for specific cha- 

 racters as in my attempts to distinguish the true names of the 

 Cuban JussceicG from the synonymy which accompanies them- 

 A glance at this shows that there is something wrong — that 



many species have been established on insufficient data. In the 

 infancy of the science, the known species were few, and could 

 be well characterized by the habit, flowers, fruit, &c. But at 

 present marks of distinction less variable should be sought, and 

 I have been surprised to observe how rarely the number, form, 

 or arrangement of the seeds is noticed ; yet they give most 

 excellent characters. 



In the species examined, there are two principal modes in 

 which the ovules are arranged in the ovary-cells — imiserial and 

 pluriscrial, or crowded, I fiud, in Kunth, three good analytical 

 figures, of which I shall make use in tlie following observations. 



I have determined, more or less satisfactorily to myself, the 

 following as Cuban Jussicece. J, repeiu, L., J. peduncularis^ 

 AVr., J. oocarpcfy Wr., J, pilosa, Kth., J. acuminata, Sw. ?, J* i^"
