usually considerably below the pedicel to which they belong and appear 

 therefore irregularly scattered between the pedicels along the rhachis; 

 the anthers and the sepals before anthesis are nearly or quite of the same 

 length and are inserted approximately at the same height, but during 

 anthesis the axis lengthens and disarranges the floral whorls w r hich become 

 thus more or less racemose. The tendency at the same time of the parts 

 to assume an unilateral position and the absence of any vestige of an ovary 

 makes the similarity of the inflorescence to that of Populus still greater. 

 The staminate flowers of Sinowilsonia certainly show greater approach 

 to a primitive structure than those of any of the related genera and in 

 the catkin-like shape of the inflorescence resemble the incompletely known 

 staminate flowers of Fortunearia (see Rehder & Wilson in Sargent, PL 

 Wilson. I. 428) which, however, have at least a rudimentary ovary. The 

 much elongated calyx-tube of the pistillate flower, as described and figured 

 by Hemsley, represents the state as it appears some time after anthesis. 

 During anthesis it is not much longer than the ovary, but it begins to 

 lengthen afterwards, as the growing flowers on our living plant have 

 shown.

The oldest varietal name for this form is apparently rubra, based on 

 T. europaea var, rubra Weston. This is identical, at least in part, with T. 

 rubra G. Don, and probably also with T. rubra De Candolle, Cat. PI. Mon- 

 spel. 150 (1813), and Prodr. I. 513 (1825), a name applied by many auth- 

 ors to an entirely different species; a few remarks about this and T. 

 corinthiaca Bosc may not be out of place here. 



Tilia rubra was described by De Candolle in 1813 as intermediate 

 between T. microphylla (= T. cordata Mill.) and T. platyphyllos and he 

 stated that it was first separated by Bosc from these two European species 

 and that it is commonly cultivated as a shade tree under the names 

 ''Tilleul a bois rouge, " "Tilleul de Corinthe;" from the latter name he 

 assumes that it was introduced from Greece. These remarks seem to 



l K. Koch did not publish this combination; in 1853 (Hort. Dendr. 50) he cites T. 

 europaea var. corallina Ait. as a synonym of T. rubra and in 1869 (Dendr. i. 472) he 

 mentions T. europaea corallina among the forms of T. platyphyllos without making a 

 varietal combination.
