BALFOUR—NEW SPECIES OF PRIMULA. 9 
the long-stalked leaves distinguish it at sight, and there are 
many other easily recognised distinctions some of which I have 
noted above. 
The Malvacea series of Primula is a compact and definite 
one. The species are all herbaceous forms with coarse leaves 
and long racemose inflorescences bearing flowers the calyx 
of which is diagnostic. It is foliaceous with well-developed 
reticulate venation more or less elevated, and the obconical 
tube expands into broad spreading lobes. In fruit the whole 
enlarges to form a platter-like expansion in the middle of which 
rests the globose capsule, the wall of which is thickened through- 
out its whole extent. The species now known—not all with 
completeness—are :— 
. malvacea, Franch., P. blattariformis, Franch., P. Tenana, 
Bonati, P. celsiaeformis, Balf. fil_—all purple or lilac-flowered forms. 
P. bathangensis, Petitm., P. pintchouanensis, Petitm.—yellow- 
flowered forms. 
At the time of the Primula Conference I included P. neuro- 
calyx, Franch., in this section. I was wrong. It finds its 
nearest allies in the Mollis section. 
f P. racemosa, Bonati, which I had not seen at the time 
of the Conference, and which I upheld doubtfully as a species, 
I am now able to say, after an examination of a type specimen, 
that it is only a poor plant of P. bathangensis, Petitm. To 
make up for the casting out of his P. racemosa, Bonati, I 
console M. Bonati by raising his P. blattariformis, Franch., 
var. Duclouxii, Bonati, to the rank of a species. Unfortunately 
the name Duclouxii has been already attached by Petit- 
mengin to a microform of P. malacoides, Franch. and the name 
P. Tenana now given to Bonati’s plant is in honour of its collector 
Pére Siméon Ten. M. Bonati sent to me a sheet of this for 
examination. The following is the diagnosis :— 
P. Tenana, Bonati: P. blattariformis, Franch. var. Duclouxit, 
Bonati in Bull. Soc. Bot. France, sér. 4, ix (1909), 465. 
A P. blattariformi, Franch. differt foliis mollibus haud scabridis 
brevibus (4-5 cm. longis, 3-4 cm. latis) basi cordatis profunde 
lobatis, lobis rotundis ; scapo scabrido haud lanato; pedicellis 
longioribus (1-2 cm.) ; bracteis latioribus calyce multo breviori- 
bus; floribus minoribus; forma calycis post anthesin ultra 
2 cm. diametientis.

An addition to the list of the Malvacea Primulas. 
1 have no further information about P. pintchouanensts, 
Petitm. and include it as a species with still a doubt.
