BOTANICAL NOTICES OF NEW PLANTS. 



and air admitted every fine day. Artificial heat is injurious, because it causes them 

 to begin to grow at a season when the sun has but little power on the vegetation.

BIGNONIACEiE. 



Tourrettia lappacea. Willcl. Bur-fruited Tourrettia. Bot. Mag. t. 3749. 

 This plant is the only species of the genus at present known, and is more remark- 

 able from the curious structure than for the beauty of the flowers. The calyx 

 before expansion is of a bright vermilion colour ; when it becomes fully expanded 

 it is green. The corolla resembles that of a Pedicularis deprived of its lower lip. 

 The germen is clothed with deflexed, red tubercles, and is succeeded by a pretty 

 large membranous inflated capsule, clothed with long but softish prickles, strongly 

 hooked at the extremity. 



It is an annual and a native of Peru, and was found there by Dombey. By him 

 it was introduced into the Paris Royal Garden, but was afterwards lost to Europe. 

 In 1837, J. M'Lean, Esq. sent it from Lima to the Glasgow Botanic Garden. It 

 requires a greenhouse, where it will flower in the autumnal months, and until the 

 winter destroys it. Bot. Mag. 



PASSIFLORACEiE. 



Passiflora hispidula. (sp. nov.) Foliis membranaceis hispidulis trilobatis 

 ciliatis basi cordato-sinuatis subdentati apiculatis'; lobis subsequalibus obtusis 

 apiculatis ; petiolis hispidis infra medium biglandulosis ; pedicellis geminis brevis- 

 simis 2-3 bracteatis ; ovario elliptico glabro. 



Flowers in pairs, small, about an inch in diameter. Pedicels very short, with 

 2 or more generally 3 filiform, hispid, scattered bracteas. Involucre none. Calyx 

 10-lobed, with a very short tube ; exterior lobes somewhat fleshy towards the 

 base, externally of a pale green, internally of a yellowish white ; inner alternate 

 lobes small, membranous, and of a yellowish white. Crown arranged in three 

 series ; the outer one consisting of filiform spreading rays spotted with purple ; 

 the middle one formed of an erect, undivided purple membrane, closely and 

 regularly plaited, with a crenate inflexed margin, and thus presenting the appear- 

 ance of a series of hooded processes ; the inner one consisting of a simple 

 membrane, purple, erect, whence it spreads over, and forms a lining to the bottom 

 of the calyx, and terminates by uniting with the base of the shaft. 



This new species of Passiflora is exceedingly pretty, though the flowers are 

 small. It was raised at the Birmingham Botanic Garden from seeds presented 

 to that establishment by George Barker, Esq., by whom they were imported. 



LOBELIACEiE. 



Lobelia mtjltiflora. (sp. nov.) Caule erecto herbaceo basi ramoso ; foliis 

 ovato-oblongis subacuminatis hispidulis obsolete dentato-glandulosis ciliatis ses- 

 silibus ; spica elongata. terminali multiflora foliata. 



Calyx hispid, segments linear-awl-shaped, erect ; tube of the corolla slit on 

 the upper side, limb 2-lipped, upper lip with 2 narrow linear segments, lower
