To Messrs. Veitch and Son, of the Exeter and the King’s- 
road (Chelsea) Nurseries, we are indebted for the specimen of 
the very beautiful Brazilian Dipladenia here represented, in 
July, 1854. We confess that, on a cursory glance, we were led 
to consider it the same as the D. crassinoda,* Lindl. Bot. Reg. 
1844, t. 64 (assuredly however not the D. crassinoda of De 
Candolle,—Eehites crassinoda of Gardner); but, besides the 
greater size and beauty of the blossoms, the calyx is very dif- 
ferent, and no less so the very acuminated lobes of the corolla. 
Dipladenia splendens too (Bot. Mag. t. 3976, sub Achitem), has 
a good deal of resemblance to our plant in the size and colour of 
the flowers; but the calyx and corolla of that species are also 
very different, and the petioles want the curious fleshy stipula- 
ceous scales which are so remarkable in D. acuminata and D. 
crassinoda (Lindl.). The present is, no doubt, a very distinct 
* Echites crassinoda of Gardner (Hook. Lond. Journ. of Bot. v. 1. p. 544, 
and n. 250 of Mr. Gardner’s Herb. Bras.) is a small shrubby (not scandent) 
species, referred doubtfully by De Candolle to Dipladenia; and is nearly allied 
to Echites (Dipladenia) atropurpurea, Lindl. (see Bot. Reg. 1843. t. 27).
