4-28 Mr. Lecount's Tables of the Mean Time 



Descriptio. Fridex firmus ramosus erectus bipedalis 

 ultrave, ramis teretibus. Folia subuncialia laevia 

 crassiora quam in affinibus, apice obtuso mucro- 

 nulo reflectente (quasi externo) ab ima parte apicis 

 sino-uli folii. Folia juniora molliter incanescentia (uti 

 ramuli incipientes) et sub lente optimo obsolete pube- 

 rula: seniora viridiora sed mollia tactu. Flores an teme- 

 ridiani mediocres (at magni maximive suae sectionis) 

 nivei terminales saepe ternati. Stamina filamentis in 

 conum concinne collectis, petalorum vix semialtitudine. 

 Anthers pollinosae luteee. 



Obs. Calyx (cum genuine) hemisphaericus, foliolis 5, 

 horum duobus quam caeteris productim duplo longi- 

 oribus. 



Obs. Nulli multum affine, sed forte magis approxi- 

 mat M. trichotomo Thunb. quam caeteris ; unde ante 

 id locarem. 



Sectio, Barbata. 

 SjJecies. 

 bulbosum. M. (bearded tuberous) ramis villosulis, foliis hori- 

 10. zontalibus, radice tuberose 



Floret Aug. G. H. »j . 



Descriptio. Suffrutex subpedalis, radice senecto 

 lignoso strumose tuberoso subgloboso supra terram, 

 pomi mediocris magnitudine. . Rami effuso-decum- 

 bentes teretes pubescentes, internodiis folio longioribus. 

 Folia viridia numerosiora brevioraque quam in M. in- 

 tonso Nob. (in Philosoph. Mag. Jul. 1824-), magisque 

 approximata in juniorum ramorum apicibus, laeviora 

 et solum sub lente villosula, apicibus multiradiatis. 

 Flores antemeridiani mediocres hilariter rubicundi 

 observavi in Regio Horto Kewense, sed nondum dis- 

 secavi. 



Obs. Pone Mesem. intonsum Nob. locandum ; et 

 radice tubei'oso superterraneo facillime distinguitur ab 

 omnibus, M. tuberoso solum excepto ; atque ab eo bar- 

 bigeris foliis.
