described by Dr. Torrey, in the present specimens when well expanded 

 they are three lines in diameter; the fruit from 1^ to 1^ lines long, 

 usually obtuse, sometimes truncate at the summit ; pedicels half a line 

 or a line long. The stamens are 3 or 5.

95. Antigonon leptopus, Hook. & Arn. Bot. Beech. Voy. p. 308, 

 t. 69. In some specimens all the upper leaves are subsessile, and the 

 rest short-petioled. Sepals rose-red. 



96. Stegnosperma halimifolium, Benth. Bot. Voy. Sulph. p. 17, 

 t. 12. In flower and fruit. But the kernels of the mature seeds have 

 been destroyed by insects, so that the form of the embryo cannot be 

 made out. The ovary shows the rudiments of the dissepiments at the 

 summit of the cell. The five arilli cohere so that, after dehiscence, the 

 contents of the capsule fall as a globular mass.

98. Celosia FLORiBUNDA (sp. nov.) : caule herbaceo (vel suffruti- 

 coso ?) ramoso fere glabro ; foliis coriaceis deltoideo-ovatis nunc subhas- 

 tatis trilobisve basi in petiolum decurrentibus subtus tomentulosis pu- 

 berulisve reticulatis ; spicis subdensifloris paniculatis, paniculis in thyr- 

 sum amplum corymbiformem confertis ; floribus plerumque digynis ; 

 sepalis albidis ovalibus obtusissimis ecarinatis obsolete 3 — 5-nerviis 

 bracteas uninerves triplo superantibus; ovulis seminibusque 3-4; utri- 

 culo calycem adaequante. — Rami validi, striata. Folia cum petiole 

 4 — 6-lin. longo 2 - 3-pollicaria, crassa, scabrida, mucronata, ovata seu 

 ovato-lanceolata, nunc Integra, nunc subtriloba vel subhasta, lobis rotun- 

 datis. Thyrsus maxime floribundus densus. Flores sessiles, vix ses- 

 quilineam longi, scarioso-albi, denique fuscescentes. Stamina ima basi 

 monadelpha. Utriculus ovoideus, circumscissus. — This would appear 

 to be allied to the Arabian and Abyssinian C. popuUfolia.

* Moquin-Tandon's first thoughts, which were to combine his Sarratia and Am- 

 blogyne, seem to have been the best, and, in the next general revision of the order, 

 when the subdivisions come to be grounded upon characters of more consequence 

 than transverse dehiscence or the want of it, will probably be acted upon. Amblogyne 

 will thus form a natural and pretty well defined genus, distinguished by the nature 

 of the sepals of the female flowers, their union at the base, which hardens more or
