Botany lab four: Seedless vascular plants

Dicranopteris linearis

The field walk began in the northeast corner of the campus with Nephrolepis hirsutula, Davallia solida, Davallia pectinata, Davallia heterphylla, Microsorum scolopendria, and Phlegmariurus phlegmaria.

The class then walked west to the Dicranopteris linearis and Blechnum orientale. Then the class went out into the soccer field to view an orchid, Spathoglottis micronesiac, and Palhinhaea cernua with strobili.

The weather was wet with intermittent light rain. At 11:00 a drenching downpour paused the class from starting the walk. Eleven of the 15 students had seen the seedless vascular plant slide deck in ethnobotany class either this term or in a prior term. A brief run through of the deck was sufficient time for the weather to break from a drenching tropical downpour to the conditions seen above.

Psilotum nudum

The class remained on the road until the access road to counseling and the residence halls. Then the class moved inside the fence as the Psilotum nudum and Psilotum complanatum are on a tree west of this gate.

Haploteris elongata

Haploteris elongata (Vittaria elongata) was also see on Pterocarpus indicus west of the gate.

Ixora spp. 

The decision was made to see the condition of the Cyathea nigricans and an area of the campus that has been long unvisited. The problem is that Hibiscus tiliaceus is encroaching on this area. A whole cutting session would be necessary out here.

The Asplenium nidus is quite large and sprawling at this point

Asplenium polyodon

Angiopteris evecta

Angiopteris evecta has appeared off the southwest side of the cemetery. Access may involve clambering over the hidden tower base - treacherous and dangerous at best.

Setting up a boxplot chart in Google Sheets with multiple boxplots on a single chart

Image
The  Google Statistics  add-on for Google Sheets can display multiple boxplots in a single chart. The key is the layout of the data. One column should be the variable by which the data is to be grouped, the other column should be the data to be box plotted. Set up the Statistics add-on with the data to be plotted as the variable, and the grouping column as the "by" variable. In this image I had deselected all but the boxplot option, the result was the appearance of the Moment, Standard errors, and Confidence intervals options. The default is apparently a 95% confidence interval for the mean. The result is multiple boxplots on a single chart with a common scale. The new tab that is created also quotes 95% confidence intervals for the mean. Note that as of 2018 the Google Statistics add-on cannot be found by search in the add-ons. In addition, as of May 2018 the add-on no longer verifies, possibly due to the add-on not having been updated since August 2017. One may ha...

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, o...

Plotting polar coordinates in Desmos and a vector addition demonstrator

Image
In an earlier post I noted that Desmos did not directly plot polar coordinates. Not only was I incorrect, but Desmos responded to my blog to correct me! Although I had at some point seen that one could define a function f(x)=3x+5 and then have Desmos calculate f(6), I had not absorbed how this might be used to plot polar coordinates. The above works beautifully . Realizing that I could effectively program Desmos, I applied this thinking to demonstrating how to add two vectors when given the magnitudes m and the direction angles theta. The graph calculates the i and j components for the two vectors and then adds the vectors, graphically displaying the result while also providing information on the magnitude and direction of the vector sum. m1 and theta1 are the magnitude and direction angle for one of the two vectors, m2 and theta2 are the magnitude and direction for the other vector. All four are dynamically interactive and can be changed. The diagram purports to illustra...
