CRASSULACE.E QUATUOR NOV^: CHINENSES. 5

 bus clivergentibus. 



In common with Q. Teijsmanni, Bl., and Q. Irwinii, Hance, the 

 leaves of this species give out a resinous exudation, causing them, when 

 washed over with spirit, to shine as if varnished. 



I avail myself of this opportunity to state that the opinion recently 

 expressed by me (Linn. Journ. Bot. x. 489) that the nearest allies of 

 Q. dentata, Thbg., notwitJistandiug the annual maturation of its fruit, 

 are very probably Q. Cerris, L., and Q. pseudo-snber, Santi, has received 

 unexpected and valuable support by the positive declaration of Parla- 

 tore (Fl. Ital. iv. 176) that each of these last-named species fruits in 

 the year of its growth ; Michaux and Gay's assertion to the contrary, 

 acquiesced in by A. De Candolle, and which I had supposed unimpeach- 

 able, being, according to the Florentine Professor, erroneous. 



CRASSULACEAS QUATUOR NOVAS CHINENSES, 



Describit H. F. Hance, Ph.D., etc. 



I. Kalanchoe viacrosepala, n. sp. ; glaberrima, glauca, foliis basi 

 paulo ampliata semiamplexautibus a medio pinnatifido-laciniatis seg- 

 mentis varie sectis vel integris lineari-oblongis sumniis iutcgerrimis 

 ^2~^\ poll- lotigis 2|~7 lin. latis, cymis terminalibus subcorymbosis, 

 calycis laciniis usque ad basin discretis lanceolatis acutis patentibus 

 corolla lutea urceolato-hypocraterimorpha vix brevioribus. (Exsicc. n. 

 1723). — A Sinis culta. Specimina mea obtinui in ins. Hongkong, Aprili 

 1858. — Hanc primum pro K. lacininta,J)e dmA. habueram ; veram 

 tamen ejus necessitudinem potius esse cum K. variatiti, Haw., aliquot 

 abhinc annis statuit ille Bentham. Sed folia, etiamsi ampliora quam 

 in tabula Wightiana (Icon. pi. Ind. Or. iii. t. 1151), A. laciniatae de- 

 pinguntur, art'hitectura illis omniuo conveniunt ; dum ea K. variantis, 

 testibrus Hookero filio et Tliomsonio, sunt " crenata, obtusa, inferiora 

 simplicia ovata, suprema trifoliata." (Journ. Linn. Soc. Bot. ii. 91.) 

 Nostra species calyce magno,* necnon corollse suburceolatee tube brevi, 

 distinctissima videtur. 



* The sepals of Kalanchoe, which are united into a tube, retain their form 

 with scarcely any modification in each species. (Hook, and Thorns. FL Ind. 

 Introd. Ess. p. 29.)
