on Zoology and Botany. 233 



Brazil. Subjoined to this Number is the Index of the eighth volume of 

 this truly valuable publication, and another Index of all the plants con- 

 tained in the work. 



Curtis's Boia?iical Magazine. No. ^SS. 

 PI. 2378. Hedj/chium Jlavum of Dr. Wallich, from Bengal. The next 

 plate represents a new genus under the following name and characters : 

 Schizopetalon IVcUkeri. " Cal. cylindraceus, basi aequalis, clausus. Pe- 

 tala ovata inciso-pinnatifida. Stigmata gibbosa, approximata. Caetera 

 desunt." This is an imperfect character ; but, as far as it goes, strongly 

 indicates a genus that cannot be united with any yet known : it belongs to 

 the class and order of Tetradynamia SUiquosa, and was received from China. 

 Aitrngalus stipitatus, a new plant of this numerous genus, recently disco- 

 vered in Nepal. " A. foliolis multijugis ovato-oblongis obovatisve mucro- 

 nulatis glabris, stipulis maximis foliaceis, spicis tenuifloris, leguminibus 

 compressis glabris stipitatis cernuis." Boltonia glastifolia Willd. Brodicea 

 Ixioides. This adds another species to the two already known of the genus. 

 " B. coronae foliolis subulatis." It is a native of Chili. The concluding 

 plate (2383) represents the white variety of Azalea pontica. 



Loddiges's Botanical Cabinet. Part 70. 

 This part concludes the seventh volume of the work: we therefore take 

 another opportunity of pointing out to the authors, the great and essential 

 improvement they can very well commence in a nev/ volume ; that is, by 

 giving some one or two references (or synonyms) to those authors who may 

 have previously described the plants selected for this work. We do not 

 want intricate synonyms cleai'ed up, or learned disquisitions on natural 

 families ; which, however useful and important to science, are not adapted 

 to a work of this nature; but we strongly recommend a reference either to 

 Linnaeus, the Hortus Kewensis, Willdenow's Species Plantarum, the Bo- 

 tanical Magazine, or the Botanical Register. Some one of these books are 

 in the hands of almost every one who takes an interest in this delightful 

 pursuit; and thus they would be enabled to learn something more of the 

 history of any particular plant, beyond whac is given in the Cabinet. One 

 thing is certain, that the authors themselves wiist consult some books to 

 ascertain the names they affix to their plants ; let these authorities there- 

 fore be given to such as are already described ; and, with regard to such as 

 are not, the fact being mentioned would be sufficient. We make these 

 remarks purely from a fondness for this interesting little book, and with a 

 wish of seeing its neat plates, and useful notices, rendered more valuable to 

 the botanist than they are at present.

 class mutually impregnate each other. By Sir Everard Home,
