since when it has grown admirably and proved quite hardy. 
Wilson describes it as a tree up to 65 ft. high with a trunk 
occasionally 9 feet in girth. The young shoots are thickly 
clothed with hairs. Leaves ovate or roundish-ovate, deeply 
cordate at the base, contracted at the apex to a shortly acuminate 
tip, evenly and minutely serrate; they are from 3 to 43 in. long, 
rather less wide, glabrous above except on the main nerves, 
covered with stellate pubescence beneath; petioles 14 to 2? in. 
long, pubescent. Sepals ovate-lanceolate, } in. long; petals 
oblong-lanceolate, 4 in. long, ;; in. wide. Fruit ovoid, 2 in. 
long, distinctly five-ribbed. 
_ Tilia intonsa is distinguished from all the other Chinese 
limes by its very hairy young branchlets. Other distinctive 
characters are the absence of tufts of pubescence from beneath 
the leaf in the axils of the chief veins, and the stellate form of 
the pubescence. The species was originally called ‘ Tilia 
tonsura ’’ by Messrs. Veitch and offered by them under that name 
in their catalogue of New Chinese Plants for 1913. It may 
still be grown as such in some gardens or under Wilson’s seed 
number 1569, but it is not common. 
XVII._THE GENUS HEYWOODIA. 
J. HuTcHrnsoy. 
In his work* on the Forest Flora of Cape Colony, published 
in 1907, . T. R. Sim described a striking new genus of 
Euphorbiaceae from South East Africa which he named in honour 
of Mr. A. W. Heywood, Conservator of Forests, Transkei. In 
describing this plant for the Flora Capensis the present writer 
had before him only very imperfect material, and in consequence 
the account given therein was somewhat inadequate. In revising 
the naming of the South African Euphorbiaceae for the National 
Herbarium, Pretoria, a fine series of specimens of this genus, 
preserved in the Forestry Herbarium of Cape Colony, has been 
seen, from which the following more complete and accurate 
description has been drawn up. 
on an adventitious shoot. This fact seems to point to the 
peltate character being an ancestral type which is retained in 
the seedling and in adventitious shoots produced by injury or 
other causes, and that the basally attached leaf is an ecological 
condition not yet finally established. ' Peltate leaves are almost
