Begonia Species

.

August/September

I recently received four Begonia cuttings from Jacky Duruisseau plant hunter and the Vice President of AFABEGO. All the plants belonging to section Gireoudia and are current housed in a large terrarium.


B. bowerae var. nigramarga
is a small plant with a creeping rhizome. The characteristic hairs on the leaf edge gives B. bowerae its common name the eyelash begonia and this variety [nigramarga] has a darker variegated leaf pattern than B. bowerae var bowerae.
 


. 
B. strigillosa is another small plant belonging to the section Gireoudia. It is also rhizomatous and is found from southern Mexico to Panama at altitudes between 1350m and 2800m [thats almost 1-2 miles high] so it should do well at lower temperatures. Its maculate [spotty] leaf pattern is said to be highly variable across its range. It likes high humidity, but, dry roots.

 


B. squarrosa
is an attractive rhizomatous species endemic to Mexico. I have not yet been able to find any further information on this plant. Jacky says it likes high humidity, but, dry roots and does best in a terrarium. As with many of the plants within section Gireoudia it has hairy petioles
.

B. lindleyana has an upright rhizome and very attractive leaf covered in small hairs. There is some debate within the literature as to whether B. lindleyana is a distinct species or a variant of B. sericoneura.

 


Many Begoias have hairy leafs or petioles. Within the section Gireoudia there is a wide diversity of petiolar induments. These distinctive hairs/scale can be used to help with plant identification. For example, the leaf of B. lyman-smithii is bordered with a margin of rust coloured brown hairs.
 

 

Microscopic examination of these hair like structures reveals further details impossible to appreciate with the naked eye. Here are a few examples:

                         B.squarrosa, (1)          B. heracleifolia, (2)          B. quartana (3)          and B. croatii. (4)
    (1)                       (2)        
 (3)                         (4)

Jeff Rhodes came to visit my collection on Monday 20/09/16. He brought me a very nice plant B. acetosa. It was good to meet Jeff and his friend and we had an interesting discussion on growing begonias.



 

I attended the annual congress of AFABEGO this weekend 24/09/16. Despite my trepidation, to my shame I donít speak any French, I received a very warm welcome. The meeting was held just outside of the city of Rennes in the school of horticulture at St Gregoire.  We visited a tropical style garden and begonia collection close to where the meeting was held, followed by the AMG, competitions, annual plant exchange [members donate plants to a central pool then are able to look through and select plants they would like] and the annual dinner. I enjoyed the day and made some good contact with begonia collectors from all over Europe.
