Dichotomous Key Activity: Fill & Download for Free

Use the appropriate dichotomous keys on morphology, selective plates, enzyme activity, and endospore presence. Wikipedia surprisingly has the same information as Bergey’s Manual.

It sounds like you have not bothered to learn basic botanical terms. One has to learn these before beginning to use botanical dichotomous keys. The veins are arranged in a pinnate manner. The word is from Latin pinnatus ‘feathered’. A “pinnate” venation describes a visible pattern on a leaf where there is a dominant center vein, or “mid-rib” with other veins branching off from the middle.Avocado—-Persea americana. Family: Lauraceae.It is native to South Central Mexico. Native people in Central America domesticated them. There is evidence for three possible separate domestications of the avocado. The oldest avocado pits have been found in caves dating from around 9,000 to 10,000 years ago. It was cultivated as early as 5,000 BC. The wild native, undomesticated variety probably coevolved with extinct megafauna.Leaf arrangement: alternateLeaf type: simpleLeaf margin: entireLeaf shape: elliptic (oval)Leaf venation: pinnateLeaf type and persistence: evergreen, broadleaf evergreenLeaf blade length: 4 to 8 inchesLeaf color: greenFall color: no color changeThe sexual organs of avocado flowers are unusual in that they are active at different times of day (dichogamy). The types with the “A flowers” kind of flowers are female (receptive to pollen) in the morning and male (shedding pollen) in the afternoon. The plants with “B flowers” are male (shedding pollen) in the morning and female (receptive to pollen) in the afternoon. Here is the avocado flower.

I’ll share my experiences with the xxTP types, primarily in a work environment.These types are “builders” at heart. However, their interests in and approaches to building are different:xNTP vs xSTP types (Intuitive vs Sensing)xNTP types start with a conceptual approach. These types tend to understand theories easily.xSTP types start with a practical, hands-on, or building block approach. These types tend to have great hand-eye coordination and visual acuityIxTP vs ExTP (Introverted vs Extroverted)IxTP types are more interested in working on thingsExTP like to work with people, on things.In a team work project, these four types might be efficiently be tasked to:ENTP: (Conceptual, People Oriented) Understand user needs, conceptualize (invent) a device to meet needs, hold idea jam session with technical staff to get buy-in, test prototypes with end user.INTP: (Conceptual, Things Oriented) Design system architecture, software architecture, and proof of concepts. Build frameworks.ISTP: (Practical, Things Oriented) Fabricate prototype components of any complexity and detail level. Resolve fit, material, and design issues.ESTP: (Practical, People Oriented) Build interdepartmental rapport, coordinate prototype completion, create practical manufacturing workflows and understand people’s true needs. Train people on proper and safe use of tooling.Problem SolvingAll four xxTP types like to talk ideas, with the xNTP having more conceptual ideas, and the xSTP having more practical ideas. All four types are typically the most calm and focused when deeply engaged in the work of problem solving including when discussing ideas. In fact, they can appear so laid back that some J types may become critical of the methods, yet appreciative of the results, and somewhat jealous of the ease. It’s one of ironies of dichotomous personality characteristics. Planned, scheduled, and on time may be nice J characteristics to have, but may clash with P flexibility and agility. The xxTP types use their flexibility and agility to get complex things done, no matter what tough issues crop up during the process.TeamA team formed of these four personality types can be dangerous to opponents because of unpredictability. Rules and norms will be considered guidelines. Stupid rules will be ignored. Getting things done right, safety, and team coordination will be a priority. Tough problems would get broken down to a conceptual side and a practical side, and taken care of quickly as possible. Formality and titles go out the door, and efficiency will be key.ISTP vs. INTPI’ll share a story to illustrate the differences between INTP and ISTP problem solving styles. The INTP (90%+ N) is me and the ISTP is a friend.We go over to ISTP’s house one day and he and his wife have decided that their dry swimming pool is a risk for their soon-to-be toddler. Since it’s a huge concrete lined hole in their backyard not easily filled we discuss some ideas… “convert to bomb shelter… wine cellar”, etc. I go home in INTP-style problem-solving mode, running mental sims on the possible solutions, costs, benefits, an risks.thinking about how costly it will to fill in. If it had been my pool, I would have thought about the problem easily 2–3 years, or till we moved out.Next time we went to ISTP’s house a month or two later, the pool was all filled in with dirt! “How much did it cost to get filled?” I asked, envisioning a crew pulling down the gate and bulldozing in many loads of soil. After all, the husband is a freelancing programmer and makes a frickin’ ton of money per hour, so work a few hours behind the computer and hire multiple people, right?Er, no. ISTP problem solving is not only practical, it’s hands on action. He responds, “Well, the jackhammer was pretty cheap to rent.” “Jackhammer?” I asked, incredulously. “Yeah, the concrete was thicker that I thought, so it took about three hours.” “3 hours?”. My brain was about to explode. “…well then did you have to take the gate off so they could bring the soil in?”. “Nah, I just asked them to dump the dirt on the driveway and used a wheelbarrow to bring it to the back.”. “You wha…yourself??” I was furiously calculating in my head, loads, hours, and how much he could have made if he had been programming instead. “Er, how long did it take?” “It took longer than I thought, a few days”, he shrugged.I was dumbfounded that anyone could have come up with a solution that took so much of his own energy. When I think of solutions, I always consider systemic efficiency, and in my models, my time and energy is worth a lot. As an INTP, automation, planning, specialized tools, and hiring out are almost always part of my “optimal” solution, leaving me with the most intellectually interesting parts. But for an ISTP, that type of “lazy” solution is barely on their radar, because physical activity is rewarding. I’ve encountered two ISTPs just like this. They will identify the problem, break it into doable parts, and then get started. No nonsense, no drama.
