'Not able to change linestyle in Seaborn plot

I have a dataframe modified from iris dataset where there is 1 numeric and 2 categorical columns:

       PL     Species group
  4.400  versicolor     A
  1.600      setosa     B
  5.600   virginica     A
  4.700  versicolor     B
  6.100   virginica     B

I want to plot a seaborn lineplot with lines in black color and with different linestyle for each Species. I tried following codes:

sns.pointplot(data=rnegdf, x='group', y='PL', hue='Species', 
         color='k', style='Species'); plt.show()
sns.pointplot(data=rnegdf, x='group', y='PL', hue='Species', 
         color='k', hue_kws=dict(ls=['-','-.','.'])); plt.show()
sns.pointplot(data=rnegdf, x='group', y='PL', hue='Species', 
         color='k', linestyle='Species'); plt.show()
sns.pointplot(data=rnegdf, x='group', y='PL', hue='Species', 
         color='k', linestyle='Species', style='Species'); plt.show()
sns.pointplot(data=rnegdf, x='group', y='PL', hue='Species', 
         color='k', linestyle='Species', style='Species', dashes='Species'); plt.show()

However, they all plot solid lines only:

Why I am not able to change linestyle in this code?
