Lionstone Investments has announced that it has entered into an agreement with Austin-based smart building software company Bractlet to implement its technology at 31 office properties totaling nearly nine million square feet, about half of its total US portfolio, the company said.
Bractlet's ability to identify opportunities to optimize capital investment and streamline costs for asset owners is tied to its analysis tools which merge building design information with operations data.
These traits included: (1) resin secretion by floral bractlets, (2) pollination by resin-collecting bees, (3) the presence of large involucral bracts, (4) nocturnal closure of these bracts, (5) the tendency of sepals to envelope the pistillate flowers, (6) resin secretion by the pistillate sepals, (7) presence of sharp, detachable trichomes on the pistillate sepals, (8) closure of the involucral bracts around the developing fruits, and (9) resin secretion by leaves and stipules.
From mapping ecological relationships and traits of ecological significance onto representative maximally parsimonious phylogenies and the consensus tree, I inferred that resin secretion by floral bractlets originated prior to its role as a pollinator reward.
The bractlets homologous to those that make up the resin gland are present and, in D.
