The Chicago Botanical Garden is currently hosting an Orchid Show that features some amazing displays, including an historical orchid timeline* and we have the honour to show-case it here, for you. 
*A few more time-events were added to this digital adaptation produced by OrchidCambodia.

This study marks a new step forward in orchid research in Cambodia - and will greatly help us to complete the orchid checklist. It also illustrates perfectly the importance of the National Collection in the work of preservation and research. 

Excerpt from the introduction:
'The orchid flora of Cambodia is still inadequately known. In the most recent enumeration (Seidenfaden, 1992), 164 species were listed for the country. More species have been discovered since, especially by Cedric Jancloes and Marpha Telepova (pers. comm.), but relatively few records have been formally published (Telepova, 2009, 2013; Averyanov, 2013). It is also worth noting that 21 species of Cambodian orchids, some of which represent new records for the country, are described by Leti et al. (2013) and illustrated with colour photographs. Considering the high orchid species richness of the neighbouring countries of Thailand, Laos and Vietnam, it is probably a conservative estimate that at least 500 orchid species occur naturally in Cambodia.'
