and of somewhat different shape. Along the inferior side of the 

 corolla tube and extending into the inferior lobe is a group of 

 usually five orange colored stripes, which I call the "lyra." The 

 stamens are four, in two pairs, arranged so that the four large 

 anthers are contiguotis in two pairs and adjacent to the upper 

 arch of the corolla. There is also an upper median, short 

 stamen-vestige, usually somewhat bent to the right or left. 

 These well known details are given for a better understanding 

 of the variations noted below: 



1. Small, more or less abortive, flowers appear late in Sept. 

 and Oct. ; but it is remarkable that such were from the first on 

 the same spike with and among large, perfect flowers, without 

 intermediate forms. Later with cooler weather and slow 

 growth thev became numerous. The corolla was only 20-30 

 mm. long and the lobes, always of the normal number, were quite 

 small and not at all or little spread out. The colors were paler 

 than in the large flowers. The stamens were nearly straight or 

 irregularlv curved, isolated and not joining above and the anthers 

 were small, pale, more or less abortive, yet usually bearing some 

 pollen. The vestigial stamen was always present and the calyx 

 of the usual shape but comparatively somewhat larger than the 

 corolla. At least part of the flowers were fructescent, as the 

 ovularies grew so far as the weather permitted. The bumble 

 bees are regular visitors of the flowers and the latter may have 

 been pollinated from the large perfect flowers. 



2. In some cases there is only one upper lobe of the corolla 

 and not a trace of the stamen vestige; otherwise corolla, sta- 

 mens, and calyx are normal. Over a dozen such flowers were 

 seen on a few plants during 1905. 



,3. One flower, observed Aug. 31, 1905, was very abnormal. 

 There were four corolla lobes, apparently an upper, lower, and 

 two lateral, yet the who'e upper part of the corolla appeared 

 to be wanting. The lower part had the usual "lyra" and the 

 right and left sides and lobes each with faint lyra markings. 

 There were four stamens spreading and curving about irreg- 

 ularly with the anthers arranged T-shape on the filaments rather 

 than lengthwise. There was no trace of an upper stamen 

 vestige. The calyx was divided irregularly into two parts down 

 to the pedicel, a smaller portion consisting of one lobe on the 

 right, upper side and a larger one with three somewhat rudi- 

 mentarv lobes. The fruit resulting from this flower is also 

 abnormal ; the pod is straight, of the same formation above and 

 below; the projecting crest on the upper side is wanting; both 

 halves of the beak are curved to the left. 



4. In some otherwise normal flowers, the upper' stamen 

 vestige grows to one-third and even to fully the length of the 

 other stamens, and has a more or less well developed anther 

 sometimes even with some pollen.
