Web Scraping on href text

[Superzaffo]

Thank you
I wrote this code:

from urllib.request import urlopen
from bs4 import BeautifulSoup
import re

html = urlopen('http://www.orchidspecies.com/indexe-ep.htm')
bs = BeautifulSoup(html, 'html.parser')
images = bs.find_all('a')
for image in images: 
  prova=image.text
  if re.search('Earina sigmoidea', prova):
    #print(image.text)
    print(image.get('href')) 

But the result is not entirely correct, becouse the name 'Earina sigmoidea' in the page there is only one.
Why this ?

this is the result.

Output:
earinaaestivalis.htm
earsigmoidea.htm
