A Grammatical Dictionary of Botanical Latin

 
diffusus,-a,-um (part.A): diffuse, spread abroad, spread out, extended; diffuse, loosely, irregularly, loosely or widely spreading, dispersed, with branches diverging from axis at an angle of 45*-90*; “widely or loosely spreading” (Jackson; also Ainsworth & Bisby); “widely or loosely spreading” (Fernald 1950) [> L. diffundo, -fudi, -fusum 3. to spread by pouring, to pour out (as wine, tears, latex, sap), to pour forth; to scatter, diffuse]; see spreading; cf. repens,-entis (part.B), repent, creeping and rooting at the nodes; opp. ‘compact,’ q.v.;

NOTE: in botany ‘effusus,-a,-um (part.A)’ appears to be a synonym: effuse, spread out flat, without definite form, as in lichens (WIII); diffusus seems to be more used for shrubs: (of branches) spreading widely or loosely, spreading in all directions, straggling. Effusus seems more used for branching organs, such as umbels, panicles, etc.; see effusus,-a,-um (part.A). Effusus is used by Nylander in lichens more than diffusus;
