“…In the last ten years, several lectotypes have been designated in the Cordiaceae and Heliotropiaceae (Miller in Cafferty and Jarvis 2004; Gottschling and Miller 2006; Miller 2007; Feuillet 2008, 2013; Stapf 2010; Stapf and Silva 2013). In the preparation for the treatment of the Boraginales, or Boraginaceae s.l., for the Flora of the Guianas project, I found more taxa whose names had supposedly lost their type material when the Berlin (B) herbarium was bombed during World War II on the night of 1–2 March 1943 (Hiepko 1987: 251).…”

A large number of specimens used as original material for the description of new species were destroyed in the bombing of the Berlin-Dahlem herbarium, B, in 1943. Six lectotypes are designated here for Cordia discolor Cham., Cordia multispicata Cham., Cordia tobagensis Urb. and its variety broadwayi Urb. in the Cordiaceae and for Tournefortia paniculata Cham. and Tournefortia ulei Vaupel in the Heliotropiaceae.

The Boraginales are now universally accepted as monophyletic and firmly placed in Lamiidae. However, a consensus about familial classification has remained elusive, with some advocating recognition of a single, widely variable family, and others proposing recognition of several distinct families. A consensus classification is proposed here, based on recent molecular phylogenetic studies, morphological characters, and taking nomenclatural stability into consideration. We suggest the recognition of eleven, morphologically well-defined and clearly monophyletic families, namely the Boraginaceae s.str., Codonaceae, Coldeniaceae fam. nov., Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. Descriptions, synonomy, a taxonomic key, and a list of genera for these eleven families are provided, including the new family Coldeniaceae (monogeneric) and Namaceae (segregated from Hydrophyllaceae and comprising Nama, Eriodictyon, Turricula, and Wigandia), the latter necessitating a revised circumscription of a more morphologically coherent Hydrophyllaceae.

In pre-molecular times most scientists accepted this circumscription of Boraginaceae (e.g., Chadefaud & Emberger, 1960;Melchior, 1964b;Takhtajan, 1980Takhtajan, , 1997 Cronquist, 1981 Cronquist, , 1988Thorne, 1992), although some authors recognized one or the other subfamily at the family level. For example, Svensson (1925) andDi Fulvio (1978) removed Cordioideae, Heliotropioideae and Ehretioideae to Heliotropi aceae based on embryological studies, while Merxmüller (1960), Dahlgren (1980), and Takhtajan (1987) treated Wellstedioideae at the family level as Wellstediaceae. Conversely, Hoplestigmataceae, Hydrophyllaceae, and Lennoaceae were generally accepted as distinct families. However, the close relationships of these taxa to traditional Boraginaceae has been widely acknowledged by several authors (e.g., Jussieu, 1789; Baillon, 1891;Peter, 1893;Svensson, 1925; Chadefaud & Emberger, 1960; Melchior, 1964a, c;Takhtajan, 1980; Cronquist, 1981 Cronquist, , 1988. For example, Baillon (1891) defined the Boraginaceae as comprising nine series, which included both Boraginaceae and Hydrophyllaceae in their traditional circumscriptions. Chadefaud & Emberger (1960) considered Boraginaceae, Hoplestigmataceae, Hydrophyllaceae, and Lennoaceae to form a natural group within the order Tubiflorales. Takhtajan (1980) included these same families in the suborder Boraginineae.On the other hand, three groups historically associated to Boraginaceae have been clearly sho...
