PLANTS COLLECTED IN CHINA. 477 
LEYCESTERIA SINENSIS, Hemsl. (Hook. Ic. Pl. t. 2633), a 
new species having subeapitate flowers, was discovered by 
Dr. Henry associated with L. formosa, Wall, and L. glauco- 
phylla, Hook. f., the only other speeies known. 
LYSIMACHIA INSIGNIS, Hemsl. (Hook. Ic. Pl. t. 2634), a 
species having slender stems about a yard high, beariug two or 
three leaves at the top, and racemes of flowers on the otherwise 
naked stems below, was exhibited, together with L. paradiformis, 
Franch., L. erispidens, Hemsl., L. involucrata, Hemsl., and 
L. alpestris, Champ., to illustrate the very great variety in habit 
developed by this genus in China, where nearly sixty species are 
known to exist. 
PLECTRANTHUS CALCARATUS, Hemsl. (Hook. Ic. Pl. t. 2671), is 
so named in consequence of the large size of the corolline spurs. 
The original species, P. fruticosus, L'Hérit. (Stirpes Nova, t. 41) 
has a spur, though a short one, bence the name of the genus. 
F. Mueller (* Fragmenta,’ v. p. 51) seems to have overlooked this 
fact when describing his P. longicornis, which has a much 
shorter spur than P. calcaratus, for he says: “ Species propriam 
generis sectionem nisi genus peculiare (Ceratanthus) efformat. 
cornu procero floris [corollae] et forme calycis memorabilem." 
HELIGIA GRANDIS, Hemsl. (Hook. Ic. Pl. t. 2631), is a very 
handsome species of the only genus of Proteacee extending 
northwards into India, China, and Japan. Dr. Henry's collec- 
tion contains about half-a-dozen new species. It is noteworthy 
that this genus is represented in Ceylon and the Western Pen- 
insula of India, and westward to Sikkim in the Himalaya 
mountains. 
Quercus Rex, Hemsl. (Hook. Ic. Pl. t. 2663, ined.), is an 
exceedingly handsome species, the leaves of which are at first 
clothed with a dense woolly, almost golden tomentum, afterwards 
attaining a foot in length, becoming quite glabrous on both 
surfaces, glaucous beneath, and in shape and nervation strongly 
resembling those of some species of Magnolia. Itis nearest the 
Malayan Q. velutina, Lindl.
