Lindl. Bot. Reg. XXVII. 1840. Misc. 157: Catasclum dclloidcum Lindl. 



A new case of lliis kind of variations previously unlieard of and unsuspected in 

 ihe vegetable kingdom, has heen observed by Mr. Dunsford', who has brought me a 

 scape of Caiaselum delloideura fig. at 1S96 of ihis work in a similar state of alteration. 

 The scape itself has become 3 limes as stout as usual , the length of the raceme is 

 much reduced, the sepais and petals retain iheir form and colour ; but the Inbellum 

 instead of being arrow-headed, flat. deep purple , toothed at the base , and placed in 

 front of ihe flower, has hecome ol exactly tho same form as that of Monachanthus 

 viridis, hooded, undivided, and of a duil greenish colour tinged willi duil purpie. The 

 cohimn too , has in like manner lost its cirrhi , has shoriened , and its lengthened 

 beak has also disappeared. 



Obs. Ad haec addo, monsirosa Caiasela me saepius vidisse. Ipse possideo pul- 

 chrum specimen Calaseti Ocrstedii mixtis floribus Monachanthi. Labella hujus non 

 adeo saccato galeata, uti vulgo solent . sed dilatato saccata , subretusa. — Pulchrum 

 specimen vivum obtinui ex Wiidpark bei Polsdam anno 1857 et teneo siccum ac de- 

 piclum. Racemus billorus allerum llorem tenet Cataseti sanguinei paulo monstrosum ; 

 alierum Monachanthi. Ilic tamen etiam lobelli limbo pulchro replicato, apiculato. 

 basi serrulato , sacco basi dilatato recedit. — Cataseti callosi flores plurimum ludunt 

 ct lypos vaide diversos offerunt. Rchh. fil.
