Florebat in Regio Horto Kewense Maio 1822, 

 iterumque 1823. 



Obs. Planta vere mirabilis. Subsemiglobosam pul- 

 posam et semuncialem appareat, simulantem Mesem- 

 hryanthema minima, at singula planta composita est 

 circiter tria folia inasqualia (inferiora minora) imbri- 

 catim-arctissime adpressa, sub hemisphterico-trun- 

 cata pallide viridia, apicem versus saturatiora et sub- 

 aristata; interne concava. jSccpws erectus 4 — 5-entalis 

 filiformis nudus. Flores laxe spicati sub 3 — 4, alterni 

 pedunculati lutei, at morientes solum vidi. Stylus 1. 

 Capstda obtuse sulcata sive angiilata.

In hortis occurrit sub hoc nomine. C. papiUari si- 

 millima, at satis differt ut in charactere supra, folisique

Obs. In this place an opportunity is afforded of 

 making a few additional and useful remarks respecting 

 two species of this genus, which were first published 

 in my Suppl. PL Succ. and in my Revis. PL Succ. from 

 weak or incomplete examples : viz. 



1. The stem of C. elata described in Suppl. PL 

 Succ, p. 20, was tied up and appeared firm ; but my 

 own plant has ever had a " caulis subdebilis, basi ra- 

 mosus," and will probably so remain, although it is a 

 radical offset from the plant I described; because 

 gooseberry bushes, &c. raised from decumbent suckers 

 are said never to make upright plants. 



2. Cotyledon coruscans, Szi!jD/;Z. P/, iS'?^cc. p. 21, was 

 described from a young green plant in a very hot stove 

 at Kew, glittering in the sun's beams very much ; 

 but grown in a greenhouse it glitters not at all, and 

 usually becomes " farinoso-alba, ramosa, vix pedalis ; 

 foliis decussatis confertis incurvo-recurviscanaliformibus 

 semipedalibus unciam latis crassis; apice tenuioribus 

 planatis rotundatis, cum mucrone; pedunculo um- 



bellato
